my asus rt-ax86u wifi signal is really weak in my bedroom, what am i doing wrong?
DIAGNOSIS The weak signal in your bedroom is likely caused by a combination of "RF shadowing" and frequency attenuation. The ASUS RT-AX86U is a powerful router, but WiFi 6 (802.11ax) signals, particularly on the 5GHz band, have shorter wavelengths that are easily absorbed by dense materials. If your router is placed in a closet, behind a TV, or on the floor, the signal is being attenuated before it even leaves the room. Common culprits include drywall with metal studs, mirrored wardrobes, and co...
i'm trying to use the usb-c port to connect my macbook but it's not charging or showing a picture.
DIAGNOSIS The USB-C port on the PA278QV is for video, data, and power delivery (up to 65W), but it needs to be the only connection and your MacBook might need a nudge to recognize it as a power source.FIX First, use the USB-C cable that came with the monitor or a certified high-quality Thunderbolt 3/4 cable that supports DisplayPort Alt Mode and 65W+ PD. 1) Connect the cable to your powered-on monitor first. 2) Then connect it to your MacBook. The monitor should wake up and switch to the USB-C i...
my wifi speed on the ax55 is way slower than my internet plan, especially on my phone.
DIAGNOSIS Your device is probably stuck on the slower 2.4GHz band, or a setting is limiting throughput. Distance and physical obstacles are the usual suspects for band steering not working right.FIX First, test close to the router. Stand right next to it with your phone and run a speed test. If it's fast there, it's a range issue. If it's still slow, log into the admin page. 1) Go to Adaptive QoS > Bandwidth Monitor. Make sure QoS is disabled for testing. 2) Go to Wireless > Professional. For bo...
the ai mesh page in the settings shows my node connection is weak, but i can't run an ethernet cable between them.
DIAGNOSIS The wireless backhaul (the dedicated connection between nodes) is struggling. Walls, distance, and interference from other electronics are the usual culprits.FIX You need to optimize placement. 1) The nodes need a clearer "line of sight." Even moving them a few feet left or right, off the floor and onto a shelf, can make a big difference. 2) Avoid placing nodes near large metal objects, brick/chimneys, or appliances like microwaves and cordless phone bases. 3) In the ASUS Router app, g...
i connected my macbook pro via usb-c, but the monitor isn't charging my laptop and the usb hub on the monitor doesn't work.
DIAGNOSIS The USB-C port on the PA278QV provides data and video (DisplayPort Alt Mode) but does NOT provide Power Delivery (PD) for charging connected devices. The downstream USB-A ports on the hub are only active when the monitor is connected to a computer via its upstream USB-B port.FIX For charging: You must use your MacBook's original power adapter separately. The monitor's USB-C cable only carries video and data. For the USB hub: Connect the included square USB-B to USB-A cable from the mon...
my internet speed is way slower over wifi than what i get plugged directly into the router.
DIAGNOSIS You're likely not connecting to the 5GHz band, or you're connected to it but with a weak signal or on a congested channel. The 2.4GHz band is slower and more crowded.FIX First, check what band you're on. Log into the router and go to Wireless -> General. Make sure your 2.4GHz and 5GHz networks have different names (SSIDs). Connect your device explicitly to the 5GHz one. Then, in the 5GHz professional tab, set "Bandwidth" to "160 MHz" if your devices support it, and set the "Control Cha...
the 5ghz wifi network from my asus router just disappears randomly and i have to reboot to get it back.
DIAGNOSIS This is a classic symptom of the router's wireless driver or firmware getting confused, often related to specific device connections or channel interference. The 5GHz radio is essentially crashing and restarting, which takes it offline for a minute.FIX First, log into the router's web interface and update to the latest official firmware if you haven't. After updating, do a full reset: hold the reset button for about 10 seconds until the router reboots, then reconfigure from scratch (do...
the wps button on my ax86u doesn't work, it just blinks and never connects my device.
DIAGNOSIS WPS (Wi-Fi Protected Setup) is notoriously flaky and insecure. On this router, a blinking WPS light usually means it's timing out because the handshake with your client device (like a printer) failed.FIX Honestly, just don't use WPS. It's a security liability and often broken. Instead, connect your device manually: log into the router (192.168.50.1), go to Wireless > General, and note your network name (SSID) and password. Enter them directly on your client device. For devices without ...
the displayport connection on my proart keeps randomly flickering to black for a second, especially when i have a video playing.
DIAGNOSIS Intermittent signal loss, often caused by an insufficient quality DisplayPort cable, a marginal connection, or an incompatibility with Adaptive-Sync at certain refresh rates.FIX Replace your DisplayPort cable. Ensure it is a certified VESA DisplayPort 1.2 or later cable, preferably a short (1-2 meter), well-constructed cable. Cheap or long cables cannot reliably handle the WQHD (2560x1440) signal at 75Hz. Second, disable Adaptive-Sync/FreeSync in the monitor's OSD. Navigate via the joy...
after a firmware update, my whole network got slow and some devices won't connect. how do i go back?
DIAGNOSIS A bad or buggy firmware update can sometimes cause performance issues or compatibility problems with certain devices.FIX The first step is a full system reboot to clear any glitches. Don't just restart from the app. 1) Unplug the power from all your XT8 nodes and your modem. 2) Wait two minutes. 3) Plug in and turn on the modem, wait for its lights to stabilize. 4) Plug in the main router node, wait for solid white light. 5) Then plug in your satellite nodes one by one. Test again befo...
devices in my house won't automatically reconnect to wifi after coming back home, i have to toggle wifi off and on.
DIAGNOSIS This is often a DHCP lease time issue or a conflict with 'Smart Connect' (which blends the 2.4GHz and 5GHz bands under one name). The device gets confused about which band to use or the router's IP address assignment gets stale.FIX First, try splitting your bands. Log into the router admin page, go to Wireless > General. 1) Give your 2.4GHz and 5GHz networks distinct names (e.g., HomeWiFi_2G and HomeWiFi_5G). 2) Disable 'Smart Connect' if it's on. Apply settings. Connect your problem d...
my xt8 node just has a solid red light and my phone won't connect to the wifi anymore, what's wrong?
DIAGNOSIS The solid red LED means the mesh node has lost its connection to the main router unit. It's in a failed or isolated state, so your devices are dropping off.FIX You need to re-establish the backhaul link. First, power cycle the problematic node: unplug it for 30 seconds, then plug it back in. Give it 3-4 minutes to try and reconnect. If the light stays red, move the node much closer to the main router, ideally in the same room, and power cycle it again. Once it connects (white light), y...
my asus router app says one of my xt8 nodes is 'offline' but the light on it is solid white.
DIAGNOSIS The node itself is powered on and running, but it's lost its management connection to the main router. This is a communication hiccup, often after a firmware update or internet outage.FIX Don't factory reset yet. First, just restart the entire system from the app. In the Asus Router app, go to the main screen, tap the menu (three lines), select Settings -> Administration -> System -> Reboot. This gracefully restarts all nodes. Wait a full 5 minutes for them to come back online and re-s...
i'm getting constant disconnects on my gaming pc wired into the ax86u, but wifi is fine.
DIAGNOSIS This points to a problem with the Ethernet link negotiation between your PC's network card and the specific router port you're using.FIX First, try a different LAN port (one of the four yellow ports) on the router. If that works, the original port might have a physical fault. If the problem follows the cable, replace the Ethernet cable—cat5e or cat6 is fine. If it follows the PC, go into your PC's network adapter settings (in Windows Device Manager) and look for "Energy Efficient Eth...
how do i actually add a new xt8 node to my existing mesh? the app isn't making it clear.
DIAGNOSIS The process is straightforward but has to be done in a specific order. The app sometimes assumes you know the steps.FIX Here's the reliable way. 1) Plug the new node into power, but place it in the same room as your main router node. 2) On the main router, press and hold the WPS button for about 2 seconds until its LED starts flashing. 3) Within two minutes, press and hold the WPS button on the new node for 2 seconds. 4) Wait. The nodes will talk. The new node's LED will cycle and even...

Other Issues
i turned on the elmb sync but now my game looks super dark, can't see anything in shadows
DIAGNOSIS This issue is caused by the way the ASUS VG28UQL1A handles backlight strobing. ELMB (Extreme Low Motion Blur) works by rapidly switching the backlight on and off to eliminate ghosting and motion blur. When you enable "ELMB Sync," the monitor attempts to synchronize this strobing with a Variable Refresh Rate (VRR) signal. However, the physical act of strobing the backlight significantly reduces the total amount of light reaching your eyes because the backlight is literally off for a por...
just got this monitor and the text looks blurry or fuzzy on the desktop, is my 4k panel defective?
DIAGNOSIS This issue is almost certainly not a hardware defect of the 4K panel, but rather a mismatch between the Windows subpixel rendering engine and the monitor's native pixel density. The ASUS VG28UQL1A has a very high pixel density (PPI) for a 28-inch screen; when Windows applies standard anti-aliasing to text, it often creates a "fuzzy" or "halo" effect because the OS is trying to smooth edges for a lower-resolution display. This is exacerbated if the Windows Scaling (DPI) is set to a non-...
can i use the asus rt-ax86u with a dsl modem? i have at&t u-verse.
DIAGNOSIS The ASUS RT-AX86U is a standalone wireless router, not a modem. Because AT&T U-verse delivers internet via a DSL (Digital Subscriber Line) or Fiber connection, you cannot plug the phone line or fiber optic cable directly into the RT-AX86U. You must have a gateway or modem that acts as the bridge between the ISP's signal and the router's Ethernet WAN port. The primary conflict occurs because AT&T U-verse gateways (like the Pace 5268AC or BGW210) are "combo" units that act as both a mod...
can i use a different power adapter with my asus rt-ax86u? i lost the original one.
DIAGNOSIS The router requires a very specific, high-wattage power supply. Using a random adapter is extremely likely to cause damage because the voltage, current, and connector polarity must match exactly. FIX You must obtain an exact-specification replacement. The ASUS RT-AX86U requires one of two official specs: +19V DC, 2.37A (approximately 45W) +19.5V DC, 2.31A (approximately 45W) The connector is a standard 5.5mm x 2.5mm barrel plug with center-positive polarity. To get a guaranteed-compa...
the screen has a weird yellow or red tint on one side but not the other, especially on gray backgrounds.
DIAGNOSIS That's called color uniformity or tinting, often visible as 'backlight bleed' or 'IPS glow' that isn't perfectly even. On a factory-calibrated monitor like the ProArt, it's more noticeable, but some degree is inherent to IPS panels. A severe tint on one side, however, can indicate panel stress.FIX First, run a simple test. Display a full-screen mid-gray image (you can find these online). In a dim room, look at the screen from a normal viewing distance, dead center. If the tint is very ...
i can't get the built-in vpn fusion to work, my traffic just doesn't go through the vpn.
DIAGNOSIS VPN Fusion is powerful but finicky. The most common setup mistakes are incorrect VPN client configuration files, rules that don't target the right device, or simply not enabling the policy.FIX First, go to VPN -> VPN Fusion in the router settings. Under "VPN Client," make sure you've uploaded a valid OpenVPN config file (.ovpn) from your VPN provider and it shows as "Connected." Then, go to the "Policy" section below. 1) Click "Add." 2) Give it a name. 3) Select "VPN Client" as the int...
after a power outage, my router's guest network passwords all reset and the settings look weird.
DIAGNOSIS The router's internal memory that holds your custom settings got corrupted when the power cut out unexpectedly. It partially reset, reverting some settings (like guest networks) to default while keeping others.FIX You need to do a full, clean reset and restore from a backup if you have one. Unplug the router. Hold down the reset button on the back with a paperclip. While holding it, plug the power back in. Keep holding for about 10-15 seconds until the power LED starts blinking, then l...
can i use a monitor arm with the vg248qg? the stand takes up too much space.
DIAGNOSIS Absolutely. The stand is removable, and the monitor has a standard VESA mount pattern, but there's a specific plastic cover you need to deal with first.FIX Lay the monitor face down on a soft surface. Grip the stand neck and firmly pull it straight down and away from the monitor—it detaches with a firm tug. Now you'll see a rectangular plastic cover with four screw holes. This cover is held by four plastic clips. Use a flathead screwdriver to gently pry it off. Underneath is a 100mm ...
i factory reset my xt8 and now i can't get back into the admin page at 192.168.50.1, it just times out.
DIAGNOSIS After a factory reset, your computer is likely still trying to use old network information. It's not getting the correct IP address from the freshly reset router.FIX You need to force your computer to get a new address. 1) Unplug the Ethernet cable from your computer (if using one) and connect via Wi-Fi. The router's default Wi-Fi name (SSID) and password are on the label on the bottom of the unit. 2) On your computer, open a command prompt (Windows) or terminal (Mac) and type `ipconfi...
how do i get the gaming port on the ax86u to actually prioritize my xbox? it doesn't seem to do anything.
DIAGNOSIS The dedicated "Gaming Port" (the red LAN port) isn't magic. It's just a LAN port pre-configured in the firmware to be the target for the Gaming QoS rules. If QoS isn't set up or is disabled, the port does nothing special.FIX Plug your Xbox (or PC) into the red Gaming Port. Then, log into the router (192.168.50.1). Go to QoS > Adaptive QoS. Ensure "QoS" is toggled ON. Under "Bandwidth Setting," run the speed test to set your baseline. Then, under "QoS Type," select "Gaming." This applie...
my xt8 units get really warm, almost hot to the touch on the top. is this normal or a fire hazard?
DIAGNOSIS Yes, it's normal for these units to run quite warm. They're powerful tri-band routers packed into a small, sealed enclosure with no active fan. The top is a heat sink.FIX The fix is about ensuring proper ventilation. 1) Make sure the unit is standing upright, not lying on its side. 2) Leave at least 2-3 inches of clear space on all sides, especially the top and back. 3) Don't place it in an enclosed cabinet, on top of other hot electronics, or in direct sunlight. Putting it on a stand ...
the joystick control on the back of my pa278qv is super unresponsive, have to push really hard or at a weird angle for it to register.
DIAGNOSIS The 5-way joystick/navigation button is misaligned or has debris lodged around its base, preventing clean directional presses. This is a physical, not software, issue.FIX Power off and unplug the monitor. Inspect the joystick. Use a can of compressed air to blow firmly into the gap around the joystick's base to dislodge any dust or debris. Do not insert any tools. After cleaning, plug the monitor back in. Test the joystick with deliberate, centered presses: push directly in for each ca...
trying to set up aimesh with another asus node but the ax86u pro won't find it, the search just times out.

my vg28uql1a is stuck on 'no signal' with my ps5 even though everything's plugged in, hdmi 2.1 cable and all
DIAGNOSIS This "No Signal" state on the ASUS VG28UQL1A is typically caused by an HDMI 2.1 handshake failure. Because this monitor supports high-bandwidth 4K @ 144Hz, it requires a precise "handshake" with the PS5 to negotiate the HDCP (High-bandwidth Digital Content Protection) and the specific resolution/refresh rate. If the monitor is set to an older HDMI standard or if the PS5 is attempting to push a signal (like 120Hz) that the monitor's current firmware state isn't acknowledging, the screen...
what's the WPS button for on the asus rt-ax86u? is it safe to use?
DIAGNOSIS The WPS (Wi-Fi Protected Setup) button on the ASUS RT-AX86U is a hardware-triggered handshake mechanism designed to bypass the manual entry of a WPA2/WPA3 passphrase. When you press the physical button on the chassis, the router enters a "discovery mode" for exactly 120 seconds. During this window, it broadcasts a temporary signal that allows a compatible client device—such as a printer, a range extender, or a smart home hub—to exchange security credentials via a peer-to-peer negot...
the joystick controller on the back is stuck or really hard to press in to select things, feels broken
DIAGNOSIS This issue is caused by a mechanical failure in the 5-way directional joystick module located on the rear of the ASUS VG28UQL1A. The joystick operates on a rubberized dome switch mechanism; when the "click" or "press" action becomes stiff or unresponsive, it is typically due to one of two things: the accumulation of micro-debris (dust, skin cells, or plastic shavings) wedged between the joystick shaft and the outer plastic housing, or a misalignment of the internal centering spring cau...
the joystick controller on the back feels weird and the menu sometimes pops up randomly, is it broken?
DIAGNOSIS The 5-way joystick/navigation button can get stuck in a slightly depressed position from dust or debris, or its internal microswitch can become overly sensitive, causing phantom presses.FIX First, let's try a deep clean. Power off and unplug the monitor. Take a can of compressed air and, with the nozzle a few inches away, give a few short bursts directly at the base of the joystick. Tilt the monitor to help debris fall out. Next, use a cotton swab very lightly moistened with >90% isopr...
my new asus proart monitor is stuck on a blue screen that says ‘no signal’ even though my pc is on and plugged in, what gives?
DIAGNOSIS The monitor is powered on but isn't receiving a valid video signal from your computer. The most common culprit is the input source setting on the monitor itself or a loose cable connection.FIX First, let's check the physical connection. Power everything off. Unplug the video cable (DisplayPort or HDMI) from both the monitor and your PC, then firmly reseat it at both ends. Make sure you're using a certified cable. Power your PC on first, then the monitor. If the blue screen persists, gr...
my new gt-ax6000 router just has a solid red led and i can't get to the setup page at all.

Strange Noises
the monitor makes a faint buzzing or whining noise from the back, gets worse when i play a bright hdr game
DIAGNOSIS This phenomenon is known as "coil whine," specifically originating from the inductor coils within the monitor's internal power delivery system or the LED backlight inverter. When you enable HDR (High Dynamic Range) or increase brightness, the monitor demands significantly more current to drive the backlight to peak luminance. This increased electrical flow causes the copper coils to vibrate at a high frequency due to electromagnetism, creating that audible high-pitched buzzing or whini...
the monitor makes a faint but annoying high-pitched buzzing or whining sound, is it defective?
DIAGNOSIS That's coil whine, and it's a common electronic phenomenon, not necessarily a defect. It's often caused by the power supply components vibrating at a high frequency, which can change based on the monitor's brightness or the content displayed.FIX First, try to isolate the cause. Turn the brightness down to 50% or below using the OSD joystick. Does the noise change or go away? Display a completely white screen (like a blank document), then a completely black screen. The pitch often chang...
my asus router's fans are loud and spin up constantly, it sounds like a laptop under load, is this normal?
DIAGNOSIS The RT-AX86U Pro has an internal fan that kicks in under high CPU load (like VPN processing, heavy traffic). Constant loud noise suggests it's stuck in high-speed mode or the vents are blocked.FIX Check for and reduce CPU load.Log into the web interface, go to System Log > General Log.Look for high continuous CPU usage. Common culprits are Adaptive QoS, Traffic Analyzer, or AiProtection. Temporarily disable these features under Adaptive QoS and AiProtection to see if the fan quiets dow...
my proart monitor makes a faint but constant high-pitched buzzing or whining noise, seems to come from the top left back.
DIAGNOSIS This is coil whine from the monitor's internal power supply or voltage regulation circuits. It is often related to the monitor's brightness/backlight level or the connected video signal's refresh rate.FIX Adjust the monitor's brightness setting. The whine is often most pronounced at specific brightness levels, typically between 40% and 70%. Incrementally adjust the brightness up or down from your current setting until the noise diminishes or stops. A setting of 30% or 80% often minimiz...
why is my gt-ax6000 making a high-pitched electrical whining or coil whine noise? it's really annoying.
DIAGNOSIS That's coil whine from the router's internal power components, specifically inductors or transformers on the main board. It's a physical vibration caused by electrical current, and while generally not a sign of failure, it can be very irritating.FIX Unfortunately, there's no software setting to eliminate a physical noise like this. First, check if it's coming from the router's own power adapter brick as well. If the noise is only from the router itself, try relocating it. Sometimes pla...
my ax86u's fan is running super loud all the time, sounds like a jet engine.
DIAGNOSIS The router has an internal fan that usually only spins up under heavy load or high heat. If it's loud at idle, the fan curve in the firmware might be bugged, or the router is genuinely overheating.FIX Log into the router's web interface (192.168.50.1). Go to Administration > System. Check the "Operating Mode". If it's set to "Media Streaming" or "Game Mode," these modes can ramp up the fan. Switch it back to "Wireless Router Mode" and see if the fan noise drops after a minute. Also, on...
asus router keeps making a faint clicking or buzzing noise, is that normal or is it dying?
DIAGNOSIS A faint, rhythmic ticking or buzzing from the power adapter or the router itself is usually coil whine—a high-frequency vibration from electrical components. It's not necessarily a sign of failure, but it can be annoying.FIX First, isolate the sound. Unplug the power brick from the wall and listen to it. If the noise is coming from the brick, that's your culprit. Try plugging it into a different wall outlet on a different circuit, as dirty power can exacerbate coil whine.IF THAT DIDN...
the monitor makes a faint high-pitched buzzing or whining noise, is that normal?
DIAGNOSIS Yeah, this one's common. It's coil whine from the power supply or backlight circuitry inside the monitor. It's not dangerous, just annoying.FIX The whine often changes with the brightness setting or the on-screen content. Try lowering the brightness from the OSD menu (the physical buttons on the back). Set it to 80 or below and see if the noise diminishes. Sometimes enabling the "OD" (Overdrive) setting in the OSD under Image > Trace Free can shift the electrical load and change the no...
the monitor makes a faint buzzing or high pitched noise, especially on bright screens
DIAGNOSIS This is coil whine from the monitor's internal power supply or backlight inverter. It is a physical characteristic of some units and varies with screen brightness and refresh rate.FIX Lower the monitor's brightness from the OSD (Image > Brightness). Set it to 60 or below. This reduces electrical load. Next, change the refresh rate. In Windows display settings, switch from 175Hz to 144Hz. Lower refresh rates often reduce or eliminate the whine.IF THAT DIDN'T WORK The whine may be exacer...
Filter & Maintenance
the hdr looks washed out and gray in windows 11, not bright at all. did i get a bad unit?
DIAGNOSIS This "washed out" or gray appearance is rarely a hardware defect of the panel itself, but rather a systemic mismatch between the Windows 11 HDR metadata and the monitor's internal tone mapping. The ASUS VG28UQL1A uses an edge-lit local dimming system, which lacks the precision of Full Array Local Dimming (FALD). When Windows 11 triggers HDR mode, it often sends a signal that exceeds the monitor's actual peak brightness (roughly 400-600 nits depending on the content), causing the monito...
the colors on my pa278qv look way off and washed out compared to my old monitor, did i get a bad panel?
DIAGNOSIS You probably didn't get a bad panel. The ProArt comes factory-calibrated, but your computer's graphics driver might be overriding those settings with a default color profile or incorrect output range.FIX First, let's check the monitor's own settings. Use the joystick to open the OSD. Go to the 'Color' menu. Ensure the 'Color Temperature' is set to '6500K' and the 'Gamma' is set to '2.2'. Most importantly, make sure 'Adaptive-Sync' is Off for color-critical work, as it can affect gamma....
how do i clean the screen on this thing? the microfiber cloth that came with it just smears the fingerprints.
DIAGNOSIS Smearing happens when you're using a dry cloth on oily fingerprints or when the cloth itself has picked up dust and oils. The ProArt has a standard anti-glare matte coating that you don't want to damage.FIX Here's the shop-approved method. 1) Unplug the monitor and let it cool. 2) Use a dry, clean, new microfiber cloth (like for glasses or camera lenses) to gently wipe off any loose dust. 3) For smudges, dampen a second clean microfiber cloth with distilled water only. Wring it out so ...
is there a way to clean the screen without damaging it? the anti-glare coating seems weird.
DIAGNOSIS You're right to be careful. The screen has a strong matte anti-glare coating that can look speckled or "dirty" even when clean, and harsh cleaners can damage it.FIX Power off the monitor so you can see streaks. Use a dry, soft microfiber cloth (like the kind for glasses) first to wipe away dust with light pressure. If you need moisture, dampen a second microfiber cloth with distilled water only—never spray liquid directly on the screen. Wipe gently in one direction. For stubborn spot...
the colors look really washed out and terrible compared to my old monitor on the same pc.
DIAGNOSIS The VG248QG uses a TN panel, which has worse color reproduction and viewing angles than IPS monitors. Out of the box, its default settings are also overly bright and cool-toned.FIX Press the top menu button on the back to open the OSD. Go to Image > Color. First, set Color Temp. to User Mode. Now you can adjust R, G, B sliders. A common decent starting point is R=90, G=90, B=96. Then, go to Splendid > Mode and try Scenery or Standard mode instead of Racing Mode. Finally, lower the Brig...
the colors on my proart look washed out and weird compared to my old monitor, especially the reds. i calibrated it but it still looks off.
DIAGNOSIS The monitor is likely receiving a limited RGB color range signal (16-235) instead of the full RGB range (0-255), causing crushed blacks and washed-out colors. This is a common GPU-to-monitor handshake problem.FIX First, check and change the monitor's color format setting. Press the joystick, go to Color > Color Format. Ensure it is set to 'RGB', not 'YCbCr'. Second, force the full dynamic range output from your graphics card. For NVIDIA: Open NVIDIA Control Panel > Display > Change res...
how do i properly clean the matte screen on this asus proart? i'm worried about damaging the anti-glare coating.
DIAGNOSIS Standard glass cleaners or abrasive cloths can permanently damage the monitor's matte anti-glare coating, causing smears or dull spots.FIX Use the correct materials only. First, power off the monitor and let the screen cool. Use a dry, soft microfiber cloth (like for eyeglasses or cameras) to gently wipe away dust. For fingerprints or smudges, lightly dampen a second microfiber cloth with distilled water or a monitor-specific screen cleaner. Never spray liquid directly onto the screen....
i'm getting a weird washed out or hazy look on my vg27aq1a, colors look flat even after calibration
DIAGNOSIS The HDR mode is likely active while you are viewing SDR content. The VG27AQ1A's HDR implementation can cause this desaturated, grayish look in Windows.FIX Press the monitor's joystick to open the OSD. Navigate to Image > HDR. Set it to Off. Then, on your Windows PC, go to Settings > System > Display > HDR. Ensure "Use HDR" is toggled Off.

the lights on my asus rt-ax86u are super bright at night, is there a way to turn them off?
DIAGNOSISThe ASUS RT-AX86U's front panel has several bright, multi-colored LED indicators (Power, WAN, LAN, 2.4GHz, 5GHz, and 2.5G) designed for status monitoring. Their brightness, particularly in a dark room or bedroom, can be distracting. This is a common design feature, and ASUS provides a dedicated hardware control to manage them. FIXTo disable the lights, use the dedicated LED button on the router's front panel. Locate the "LED" button on the front face of the RT-AX86U. It is positioned o...
my asus proart pa278qv monitor just shows no signal from both my laptop and desktop, i've tried both hdmi and displayport.
DIAGNOSIS The monitor is receiving power but not a valid video signal from any input.

Press the monitor's rear joystick. Navigate to and select the 'Input Select' menu. Choose the specific port you are using (e.g., DisplayPort 1, HDMI 1). If the signal returns, the Auto Input Select function failed. Second, power cycle the entire ch...
how do i get 144hz on my vg248qg? windows only shows 60hz as an option in display settings.
DIAGNOSIS Windows is defaulting to a basic display driver or you're using the wrong cable/port. The monitor can do 144Hz, but you have to set it up correctly.FIX Right-click your desktop, go to Display Settings > Advanced Display Settings > Display Adapter Properties for Display 1. Click the "Monitor" tab. In the "Screen refresh rate" dropdown, 144Hz should appear. If it doesn't, you're likely on HDMI. This monitor's HDMI port is version 1.4, which can't do 144Hz at 1080p. You need to switch to ...
my asus vg248qg just has a black screen but the power light is on, no image at all.
DIAGNOSIS The monitor is getting power but isn't receiving a valid video signal it can display. It's almost always the cable or the source, not the monitor itself.FIX First, power cycle everything. Turn the monitor off at its button, then unplug it from the wall for 60 seconds. While it's unplugged, restart your PC or console. Plug the monitor back in, turn it on, then turn your source on. Make sure you're using a DisplayPort or Dual-link DVI cable (the ones that came with it are best for 144Hz)...
how do i get the rgb lighting on the front to just stay off? it's too bright for my living room.
DIAGNOSIS The router's default setting has the ROG-themed RGB lighting effects enabled. You want to disable it entirely, which is a simple setting change.FIX Log into the router's web interface. On the left-hand menu, go to Administration, then select the Operation Mode tab. Near the bottom of that page, you'll see a setting called "ROG Lighting." Click the toggle switch to turn it OFF. Click "Apply" at the bottom of the page. The front LED strip should go dark immediately.IF THAT DIDN'T WORK If...
my vg27aq1a monitor screen is black but the power light is on solid white, what do i do?
DIAGNOSIS The monitor is powered on but receiving no signal. The primary suspect is the input source or cable.FIX First, press the joystick on the back to open the OSD.

Unplug the video cable from both the monitor and PC/console for 30 seconds. Reconnect firmly, ensuring the cable is fully seated. Power the monitor on, then...
why does my screen go black for a couple seconds randomly when gaming? using displayport from my pc
DIAGNOSIS: The DisplayPort link is losing sync, often due to a marginal cable or a bandwidth overload.FIX: First, power everything down. Reseat the DisplayPort cable firmly at both ends. In the monitor OSD, go to 'System Setup' -> 'DisplayPort Stream' and change it from 'DP 1.4' to 'DP 1.2'. This reduces bandwidth but increases stability.IF THAT DIDN'T WORK: The issue may be NVIDIA G-Sync Compatible mode. In the NVIDIA Control Panel, under 'Set up G-Sync', uncheck 'Enable G-Sync, G-Sync Compatib...
Performance Problems
all the usb ports on the side of the monitor stopped working after i updated my computer.
DIAGNOSIS The USB hub in the monitor is powered and controlled by the upstream USB-B connection from your computer. An OS or driver update likely reset your USB power management settings or the hub driver itself.FIX Let's retrace the physical connections first. 1) Ensure the square-shaped USB-B cable (the one that came with the monitor) is firmly connected from the monitor's 'USB Upstream' port to a working USB port on your computer. 2) The monitor must be powered on for the hub to work. 3) Chec...
the power light on my router just keeps slowly blinking blue, it never turns solid.
DIAGNOSIS A slow, continuous blue blink means the router is stuck in its boot sequence. It's trying to start up its firmware but can't complete the process, often due to a corrupted firmware file or a failed update.FIX You'll need to use the ASUS recovery tool (Firmware Restoration). 1) Download the tool and the latest firmware file for the RT-AX55 from the ASUS support website onto a computer. 2) Connect that computer to one of the router's blue LAN ports with an Ethernet cable. 3) Set the comp...
after the latest firmware update, my ax86u is way slower and my devices keep dropping.
DIAGNOSIS A bad firmware update can happen, either due to a buggy release or a corrupted file during upload. The new firmware might have reset or introduced incompatible settings.FIX The first step is a hard reset. Use a paperclip to hold the reset button on the back for about 5-10 seconds until the power LED starts blinking. This reverts all settings to factory defaults. Set up the router again from scratch (don't restore a saved config file, as it might bring back the problem). Test performanc...
why is the internet speed from my xt8 nodes so much slower than what i get from the main router?
DIAGNOSIS Your wireless devices are likely connecting to the node on the slower 2.4GHz band instead of the faster 5GHz band. The nodes themselves use a dedicated 5GHz channel to talk to the router, but your phone/laptop might not be using the best band.FIX Log into the router's web interface (router.asus.com). Go to Wireless and then Professional tab. Look for the setting called Roaming assistant. Set the RSSI threshold to something like -70 dBm. This gently kicks a clinging device off a weak si...
the internet speed on my asus rt-ax3000p is way slower than what i'm paying for, even wired
DIAGNOSIS The router's hardware can handle gigabit, so a major slowdown usually points to a bad QoS (Quality of Service) setting, a wonky cable, or the built-in speed test influencing things.FIX First, disable QoS. Go to Adaptive QoS > Bandwidth Monitor in the web interface. If 'Bandwidth Limiter' or 'Traditional QoS' is enabled, turn it off. Also, go to the 'Speed Test' tab under Adaptive QoS and make sure the 'Automatic QoS' option is disabled. Reboot the router after making these changes.IF T...
Not Turning On / No Power
my asus rt-ax86u router won't turn on at all, no lights, what do i do?
DIAGNOSIS When an ASUS RT-AX86U exhibits a complete "dark" state—meaning no power LED, no WAN light, and no response to the power button—the failure is almost always located in the power delivery chain. The most common culprit is a failed AC adapter (power brick). These units use a high-amperage 19V rail; if the capacitors inside the brick fail or the internal fuse blows due to a power surge, the router receives zero voltage, resulting in a total blackout. Alternatively, the issue may be a "...
the monitor won't turn on at all, no power light, nothing. i've checked the outlet.
DIAGNOSIS No power light means it's not getting any electricity. The internal power supply or a fuse is likely dead, or there's a break in the power cord connection.FIX First, do the full circuit check. Unplug the power brick from the wall AND from the back of the monitor. Inspect the cord for any kinks, cuts, or damage. Firmly reconnect the DC barrel plug into the monitor's port—it can feel seated but not be. Try a different wall outlet without a power strip. Wait 30 seconds, then plug just t...
Setup & Installation
asus rt-ax86u setup page at router.asus.com won't load on my laptop, what do i do?
Yeah, this one's common. Your laptop isn't properly connected to the router's network, or there's a browser cache issue.First, check your physical connection. If you're using a wired setup, make sure the network cable from your laptop is plugged into one of the yellow LAN ports (1-4) on the router, not the blue WAN port. The router and modem should already be powered on.If you're trying to connect wirelessly for setup, you need to join the router's default Wi-Fi network. The network name (SSID) ...
