Acer LCD Monitor KG272 pixelated bar across the bottom that keeps getting bigger every day.

My monitor has this pixelated bar across the bottom that keeps getting bigger every day. It was small but now it's covering the entire navigation bar at the bottom. I have tried to Google it but I cant find any answers. Sometimes the bar is blue, sometimes it's solid black. I am not a tech savvy person so I need help. I really don't want to purchase a new monitor. It's hard to tell in the picture but it gets really bad to where I can't see anything at the bottom.

If you disconnect the video cable when the issue is occurring and bring up the OSD menu, do they still show? If so the issue is likely with the monitor itself and you should start the warranty or repair process. If they go away with the computer disconnected then the issue is more likely with the cable.

You can also consider the following steps:
Check Cable Connections: Ensure you're using a high-quality cable (preferably DisplayPort or HDMI 2.0) that supports the monitor's refresh rates.
Monitor Settings: Access the monitor's OSD (On-Screen Display) settings to verify that it's set to the correct refresh rate (120Hz) and check for overdrive or FreeSync options.
Graphics Drivers: Update or reinstall your graphics card drivers to ensure compatibility with your monitor using ddu uninstaller.
Test with Another Device: If possible, connect the monitor to a different computer or laptop to rule out GPU issues.

Ensure that the display cable, whether HDMI, VGA, or DisplayPort, is securely connected, and consider trying a different cable to rule out any potential faults. Connect the monitor to another computer or device to check if the issue persists, which will help determine whether the problem lies with the monitor or your current system. Additionally, lower the refresh rate in your computer’s display settings to see if it alleviates the issue. Lastly, inspect the monitor for visible damage, such as cracks or loose connections.

1. Check Display Settings & Resolution:
   Resolution:
   Ensure your screen resolution is set to the native resolution of your monitor, as a mismatch can cause pixelation.
   How to check: Right-click on the desktop, select "Display settings," and then adjust the resolution.
   Refresh Rate:
   Make sure your refresh rate is set to the recommended value for your monitor.
   How to check: Right-click on the desktop, select "Display settings," and then adjust the refresh rate.
2. Update Graphics Drivers:
   Outdated or corrupted graphics drivers can lead to display issues.
   How to update: Go to Device Manager (search for it in the Windows search bar), expand "Display adapters," right-click on your graphics card, and select "Update driver".
   You can also download the latest drivers directly from the graphics card manufacturer's website.
3. Check Cables and Connections:
   A loose or damaged cable can cause display problems.
   Try a different cable or port to see if the issue persists.
   Ensure the cable is securely plugged into both the monitor and the computer.
4. Hardware Issues:
   If the problem persists after trying the above steps, it could be a hardware issue, such as a failing monitor or graphics card.
   Try connecting your computer to a different monitor to see if the issue is with the monitor itself.
