How do I fix my acer screen glitch in KG272 S monitor

Jake231

My monitor glitches and displays glitching black bars on the top part of the monitor. Below the glitchy bars, the frame rate seems much lower but does vary on how low and above showing a smooth and correct frame rate. I had this problem before and the result of it was that I was using more hz than the monitor could handle and it slowly got more noticeable/ worse when the bars first did appear it disappeared relatively fast but the monitor showed the bars more and more overtime and the frame rate (at the bottom part) worsened. However, after putting it back on 120 hz instead of 144hz it was fixed immediately as the monitor's hz limit I believe is 120. This is not the same issue as I have not changed its hz but the bars appeared again for 120 hz and 119.88 only when I go down in Hurtz once more (75hz) does it shortstop. The monitor I'm talking about is a KG272 S and I have a second monitor too(that is fine and isn't a car). I believe this may be a result of accidentally overclocking the monitor and now worsened over time despite fixing it. I do not want to have to stay on 75 hz, so is there a way to fix this issue?

I took a photo of my monitor using my phone and is more clear irl.

Above the bars has the desired frame rate but below it is laggy. When it is bad (8fps I imagine) it a delayed version of what is above it

To address the glitching black bars and varying frame rates on your Acer KG272 S monitor, consider the following steps:

1. Check Cable Connections: Ensure you're using a high-quality cable (preferably DisplayPort or HDMI 2.0) that supports the monitor's refresh rates.
2. 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.
3. Graphics Drivers: Update or reinstall your graphics card drivers to ensure compatibility with your monitor using ddu uninstaller.
4. Test with Another Device: If possible, connect the monitor to a different computer or laptop to rule out GPU issues.
5. Factory Reset: Consider resetting the monitor to factory settings as a last resort.

If issues persist, it may indicate hardware degradation, potentially due to previous overclocking attempts.
