Question 1

the screen has these weird faint vertical lines or shadows, mostly on gray backgrounds, is my monitor defective?

Accepted Answer

DIAGNOSIS Those are likely uniformity issues, sometimes called 'dirty screen effect' or 'vertical banding'. It's a common panel lottery quirk in IPS-type monitors, where slight variations in the liquid crystal layer cause shadows. It's most visible on solid gray or muted colors. FIX First, rule out the cable and source. Try a different HDMI cable and see if the lines change or disappear. Open a pure gray test image (search online) full screen. If the lines are static and always in the same place, it's the panel. You can try a gentle panel refresh: power the monitor off, unplug it from the wall for a full 60 seconds, then plug it back in and turn it on. This can sometimes reset the power to the panel and minimize the effect. IF THAT DIDN'T WORK Check if it's related to a specific setting. In the monitor menu, go to 'Picture' and turn 'Sharpness' down to 50 or below. High sharpness can accentuate these subtle panel imperfections. Also, ensure 'Response Time' (in the 'Game' menu) is not set to 'Faster' or 'Fastest', as this aggressive overdrive can cause faint coronas or shadows. HEADS UP If the lines are bright, flashing, or cover the entire screen in a pattern, that's a sign of a failing T-Con board or loose internal cable and is a defect. If the faint shadows are only noticeable on test screens and not during normal use (watching videos, browsing), it's considered normal for the panel type and probably not worth a warranty claim.

Question 2

i have two computers but only one hdmi port on this monitor, do i really need to crawl behind and swap the cable every time?

Accepted Answer

DIAGNOSIS You've hit the main limitation of this model—it only has one HDMI port and one DisplayPort. To switch between two HDMI-only sources (like two laptops or a PC and a game console), you'll need some extra hardware, as the monitor itself can't switch between two inputs on the same port type. FIX The simplest fix is to buy a small, passive HDMI switch. It's a little box with multiple HDMI inputs and one output. You plug both your computers into the box, plug the box's output into your monitor, and the box comes with a button or remote to switch between them. Look for an 'HDMI 2.0 switch' to ensure it supports the monitor's 75Hz refresh rate and resolution. IF THAT DIDN'T WORK If one of your computers has a DisplayPort output, you're in luck. Buy a DisplayPort to HDMI cable (note: it's not the same as HDMI to DisplayPort). Plug that computer into the monitor's DisplayPort. Now you can use the monitor's 'Source' menu to switch between the HDMI and DisplayPort inputs without any extra hardware. HEADS UP Avoid super cheap, no-name HDMI switches. They can cause signal dropouts, not support the full resolution, or fail to pass through audio if you're using the monitor's headphone jack. Spend a few extra dollars on a known brand.

Question 3

the joystick button thing under my samsung monitor is super sensitive and keeps opening the menu when i'm just trying to adjust the tilt

Accepted Answer

DIAGNOSIS The 5-way joystick/navigation button is the only control on this monitor, and its placement means it's easy to press accidentally when you're handling the stand. It's not broken, just a design quirk you have to work around. FIX When adjusting the tilt, don't grip the monitor from the bottom center. Instead, place one hand firmly on the top edge of the monitor bezel and the other on the back of the stand's neck. Apply gentle pressure to tilt. Your fingers will be nowhere near the joystick. To move the whole monitor, lift from the base of the stand, not the screen. IF THAT DIDN'T WORK If you find yourself constantly bumping it, you can get into the habit of immediately canceling the menu. A quick, short press of the joystick in any direction will bring the menu up. If you do it by accident, just press the joystick straight in again (like a button click) to exit the menu without changing any settings. HEADS UP Be careful not to push the joystick sideways with excessive force. It's designed for navigation, not as a handle. Repeated hard lateral pressure could potentially damage the internal switch over time.

Question 4

there's a faint high pitched buzzing or whining noise coming from the back of my monitor, only when it's on

Accepted Answer

DIAGNOSIS That's coil whine. It's caused by electrical components (like capacitors or inductors) on the monitor's internal power board vibrating at a high frequency. It's not dangerous, but it can be annoying. It often gets louder when the screen is very bright or when the refresh rate is at its peak (75Hz for your model). FIX First, try changing the refresh rate. On Windows, go to Display Settings > Advanced Display > Choose a refresh rate, and select 60Hz instead of 75Hz. See if the noise diminishes. Next, adjust the monitor's brightness. Go into the OSD menu (the joystick), go to 'Picture', and lower the 'Brightness' and 'Contrast' from their max settings. A less intense image draws less power and can quiet the whine. IF THAT DIDN'T WORK The whine might be related to FreeSync. Go into the monitor's 'Game' menu and turn 'FreeSync' off. If the noise stops, you've found the culprit. You can leave it off, or you might just have to live with a faint noise when it's enabled. HEADS UP If the noise is a loud hum or crackle, or if it's accompanied by a burning smell, that's a different, serious issue. Power off and unplug the monitor immediately—that points to a failing power supply that needs repair.

Question 5

the colors look really washed out and weird on my samsung monitor compared to my laptop, tried messing with settings but it's not right

Accepted Answer

DIAGNOSIS This is almost always a mismatch in color profile or range settings between your computer's graphics output and the monitor. Sometimes the monitor's 'MagicBright' or 'Eye Saver' modes are enabled by default, which drastically alter color and contrast. FIX First, on the monitor itself, press the joystick to open the menu. Go to 'Picture' and set 'MagicBright' to 'Custom'. Then, go into 'Picture' settings again and make sure 'Eye Saver Mode' and 'Eco Mode' are set to 'Off'. This gives you a neutral starting point. Next, on your Windows PC, right-click the desktop, select 'Display settings', then 'Advanced display'. Look for 'Color profile' and try setting it to 'sRGB' if available. IF THAT DIDN'T WORK Your graphics card might be outputting a 'Limited' color range (16-235) while the monitor expects 'Full' (0-255). In your AMD or Nvidia graphics control panel, look for a setting called 'Pixel Format', 'Dynamic Range', or 'HDMI Color Depth' and switch it to 'Full RGB' or 'YCbCr444'. HEADS UP The 'Game Mode' setting on this monitor can oversaturate colors. If you have it on, try turning it off for general desktop use and see if the image looks more natural.

Question 6

how do you even clean the screen on this samsung borderless monitor? i'm scared to touch it and leave marks on the edges

Accepted Answer

DIAGNOSIS You're right to be careful. The 'borderless' design means the very thin plastic bezel is essentially flush with the screen. Using liquid or pressure near the edge can seep underneath or damage the panel seal. FIX Power the monitor off so you can see smudges better. Use a dry, soft microfiber cloth—like the kind for glasses. Gently wipe the screen in a circular motion. For stubborn spots, dampen a corner of the cloth with distilled water (not tap water) or a tiny bit of screen cleaner sprayed onto the cloth, never directly on the screen. Avoid the very outer millimeter where the screen meets the plastic frame. IF THAT DIDN'T WORK For dust in the crevice where the screen meets the bezel, use a soft, dry makeup brush or a can of compressed air held upright. Tilt the monitor back and gently brush the dust out, don't try to wedge the cloth in there. HEADS UP Never use window cleaner, acetone, alcohol, or other harsh chemicals. They can strip the anti-glare coating right off the screen, leaving permanent cloudy patches. If you get liquid in the edges, you might see dark spots that won't go away.

Question 7

the screen on my samsung borderless monitor keeps going black for a second and then coming back, happens randomly

Accepted Answer

DIAGNOSIS That's a classic sign of a flaky connection or a cable issue. The signal is dropping out momentarily. For monitors with AMD FreeSync like yours, it can also happen if the feature is enabled but your graphics card or game is having trouble syncing with the 75Hz refresh rate. FIX Start with the cable. If you're using the HDMI cable that came with the monitor, try a different, high-speed HDMI cable. Make sure it's firmly plugged in at both ends. Next, go into the monitor's menu (using the joystick), navigate to 'Game' settings, and turn 'FreeSync' to 'Off'. See if the blackouts stop. IF THAT DIDN'T WORK The issue could be with your graphics driver. Go to AMD or Nvidia's website (whoever made your GPU) and download the latest driver. Do a clean install, which will wipe old settings that might be causing the conflict. HEADS UP If you're using a cheap HDMI splitter or a very long cable (over 10 feet), that's often the culprit. Connect the monitor directly to your PC with a short, quality cable to test.

Question 8

my new samsung 75hz monitor just says no signal when i turn on my pc, but the blue power light is on

Accepted Answer

DIAGNOSIS Your monitor is powered on and working, but it's not receiving a video signal from your computer. The most common cause is the HDMI cable isn't seated properly or you've plugged it into the wrong port on your PC. FIX First, power everything off. Unplug the HDMI cable from both the monitor and your computer. Look at the back of your PC—if you have a separate graphics card (usually lower down), plug the HDMI cable into that port, not the one on the motherboard. Push it in until it clicks. Do the same on the monitor. Turn your PC on first, wait a minute, then turn the monitor on. IF THAT DIDN'T WORK The monitor might be stuck on a different input. Press the joystick button on the bottom of the monitor to bring up the menu. Navigate to 'Source' and make sure it's set to 'HDMI', not 'DisplayPort' or anything else. HEADS UP If you're using a laptop, sometimes you need to manually tell it to output to the external monitor. Try pressing the Windows key + P and selecting 'Duplicate' or 'Second screen only'.
