Question 1

every time i turn my pc off, the monitor goes into this deep sleep and won't wake up with mouse movement, have to power cycle it.

Accepted Answer

DIAGNOSIS This is a power state handshake issue between your PC's graphics card and the monitor, often related to the monitor's HDMI Link or power-saving settings. FIX Disable the monitor's deepest sleep mode and check your GPU settings. On the monitor, press the joystick. Navigate to System > Power Saving and set it to Off. In the same System menu, find HDMI Link and set it to Off. This prevents the monitor from trying to sync power states with the PC, which often fails. On your Windows PC, go to Control Panel > Hardware and Sound > Power Options > Change plan settings > Change advanced power settings. Expand PCI Express > Link State Power Management and set it to Off. IF THAT DIDN'T WORK Update your graphics card drivers from NVIDIA, AMD, or Intel's website. Also, try a different high-quality HDMI or DisplayPort cable; a faulty cable can break the wake-up signal. HEADS UP With Power Saving off, the monitor will use more energy in standby (the power LED will stay amber instead of off). This is the trade-off for reliable wake-up. The HDMI Link feature is only useful if you want the monitor to auto-switch on when you turn on a game console.

Question 2

the built-in speakers sound really tinny and quiet, is there a setting i'm missing to make them louder?

Accepted Answer

DIAGNOSIS You're not missing a setting; the 2x 2W internal speakers are a basic convenience feature. They lack bass and power by design, intended for system sounds, not media. FIX Maximize what you have, then plan for external audio. Press the volume up button on the remote or use the OSD (System > Volume). Ensure it's at 100. In the OSD, go to Sound > Treble and lower it to around 2 or 3 to reduce tinniness. You can slightly boost Bass, but it will be minimal. On your source device (PC, game console), ensure its system volume is maxed. For any real audio quality, connect external speakers or headphones. Use the monitor's 3.5mm audio-out jack or connect speakers directly to your source device. IF THAT DIDN'T WORK Check your source's audio output settings. On a PC, right-click the sound icon, select Sounds > Playback, right-click the BenQ device, select Properties > Levels, and ensure it's not muted or low. HEADS UP When using the USB-C connection from a laptop, the monitor becomes the default audio device. If you plug external speakers into your laptop's jack, you may get no sound unless you manually switch the audio output back to your laptop in the OS.

Question 3

can i clean the screen on this thing with a microfiber cloth or will i ruin the coating?

Accepted Answer

DIAGNOSIS You can and should clean it, but the anti-glare coating is delicate. Using the wrong cleaner or cloth will create permanent smudges or micro-scratches. FIX Use only a dry, clean, lint-free microfiber cloth first. Power off the monitor. A black screen makes smudges and dust easier to see. Gently wipe the screen in a circular motion with a dry, premium microfiber cloth (like the kind for glasses or cameras). This removes most dust and fingerprints. For stubborn spots, dampen a second microfiber cloth with distilled water only. Wring it out completely so it's barely damp. Wipe the screen, then immediately follow with the dry cloth to buff off any moisture. IF THAT DIDN'T WORK For persistent grease, use a screen cleaner specifically formulated for matte/anti-glare monitors. Spray it directly onto the microfiber cloth, NEVER onto the screen, to prevent liquid seeping into the edges. HEADS UP Never use window cleaners, household cleaners, paper towels, tissues, or your shirt. Alcohol, ammonia, and abrasives will permanently damage the anti-glare coating, leaving a cloudy or streaked appearance that you cannot fix.

Question 4

how do i get 4k 60hz from my nintendo switch on this monitor? it's stuck at 1080p.

Accepted Answer

DIAGNOSIS The Nintendo Switch outputs a maximum of 1080p in docked mode unless the game and system settings specifically support 4K. The monitor is just displaying the signal it receives. FIX The Switch itself cannot output a native 4K signal for games. The monitor's 4K upscaling is what you need to engage. Ensure your Switch is in the dock and the dock is connected to the monitor via a High-Speed HDMI cable (use the one that came with the monitor or a certified one) to the monitor's HDMI 2 or HDMI 1 port. On the monitor, press the joystick. Go to Picture > Display Mode. Select Display. This enables the monitor's internal scaler to upscale the 1080p signal from the Switch to fit the 4K panel. On the Switch, go to System Settings > TV Settings > TV Resolution and set it to Automatic or 1080p. IF THAT DIDN'T WORK Try a different HDMI cable. A poor-quality cable may not handshake properly, forcing the Switch to a lower resolution like 720p. HEADS UP This is upscaled 4K, not native. It will look sharper than a 1080p monitor but not as detailed as a native 4K source like a PS5 or PC. For the best motion clarity with the Switch, also go to the OSD under Picture > AMA and set it to Premium.

Question 5

the remote control for my benq monitor works super inconsistently, have to point it perfectly. is the sensor bad?

Accepted Answer

DIAGNOSIS The infrared (IR) receiver on the monitor is likely being blocked or you're dealing with low batteries or IR interference. The sensor is behind the bottom bezel, centered. FIX Start with the remote itself and your positioning. Replace the remote's batteries (CR2025). Weak batteries reduce IR signal strength dramatically. Ensure you're pointing the remote at the center-bottom of the monitor's front bezel, not at the screen. Stand within 15 feet and at a reasonable angle (not extreme side angles). Remove any obvious obstructions in front of the monitor's lower edge, like a soundbar, webcam, or thick monitor riser. Check for strong sources of infrared light, like direct sunlight or incandescent bulbs, shining on the monitor's sensor, which can flood it. IF THAT DIDN'T WORK Test if the remote works flawlessly from very close range (2 feet). If it does, the remote is fine and the monitor's IR receiver might be faulty. If it's still inconsistent, the remote is defective. HEADS UP The remote is primarily for the volume rocker, input switching, and HDR toggling. For most other settings, using the physical joystick on the back of the monitor (downward for menu) is faster and more reliable.

Question 6

why does my monitor make a faint high-pitched buzzing or whining noise, mostly on bright screens?

Accepted Answer

DIAGNOSIS That's coil whine from the monitor's internal power supply or backlight circuitry. It's an electronic noise, not a fan. It's most noticeable when the monitor is displaying very bright or high-contrast scenes, which changes the electrical load. FIX First, rule out other sources and try simple power fixes. Turn off all other electronics nearby to isolate the sound. It's definitely coming from the back of the monitor. Try a different power outlet, preferably on a different circuit. Poor power quality can exacerbate coil whine. In the OSD, go to Picture > Brightness and lower it from the default 100. Even dropping to 80 can significantly reduce or eliminate the noise. Also try disabling B.I.+ (Brightness Intelligence Plus) in the OSD under Picture, as its constant sensor adjustments can trigger the noise. IF THAT DIDN'T WORK If the whine is loud and persistent from day one, it may be a component defect. Contact BenQ support while under warranty. They are generally aware this can occur with some units. HEADS UP This is an annoyance, not typically a sign of impending failure. However, if the noise suddenly changes or is accompanied by a burning smell or visual artifacts, power off immediately.

Question 7

the hdr on my ew3280u looks washed out and grey when i turn it on in windows, is it broken?

Accepted Answer

DIAGNOSIS It's not broken; this is a classic Windows HDR configuration issue. The monitor is receiving an HDR signal, but Windows and your app/game aren't calibrated for it. FIX You need to configure both Windows and the monitor's settings together. On the monitor, press the joystick. Go to Picture > HDR and select a mode. For general Windows use, try HDR Game or HDR Cinema. In Windows, open Settings > System > Display. Turn Use HDR on. Click on Windows HD Color settings and run the HDR calibration app (search for it in the Start menu). For SDR content (like your desktop), adjust the SDR content brightness slider in the same Windows HDR settings. IF THAT DIDN'T WORK The content itself must be HDR. A washed-out look in a game usually means you need to find and enable the HDR setting within the game's own video/display options menu. HEADS UP HDR on this monitor is best for consuming HDR movies/games, not for desktop work. The brightness and backlight behavior in HDR mode will make standard desktop apps look off. Toggle HDR in Windows off when you're done.

Question 8

my benq ew3280u monitor says 'no signal' even though my macbook pro is plugged in via usb-c, what gives?

Accepted Answer

DIAGNOSIS The monitor is powered but not receiving a valid video signal from your laptop. The most common cause is the USB-C port not being set to the correct DisplayPort Alternate Mode. FIX First, check the physical connection and the monitor's input source. Ensure the USB-C cable is fully seated at both ends. Use the cable that came with the monitor or a certified high-quality USB-C 3.1 Gen 2 cable that supports DisplayPort. Press the monitor's joystick button to open the OSD. Navigate to Input and confirm USB-C is selected. On your MacBook, go to System Settings > Displays. Check if the BenQ monitor is detected. If not, restart your Mac with the monitor connected. IF THAT DIDN'T WORK The USB-C port on the monitor might need a power cycle to reset the handshake. Unplug the monitor from the wall outlet for 60 seconds, then plug it back in and reconnect the USB-C cable. HEADS UP This monitor's USB-C port provides 60W PD (Power Delivery). If your laptop requires more than 60W to charge (like some 16-inch MacBook Pros under heavy load), it may charge slowly or not at all, but this shouldn't affect the video signal.
