Acer Nitro XV275U half screen black after sleep.

KooshOveride

I been having a odd problem with my monitor only showing the left half of the screen, with the right half black after coming out of sleep(not hibernation). I have a dual monitor setup, and the second monitor is 1080(while main XV275U is 1440) so I thought that could be a issue, but problem still occurred after unplugging second monitor from desktop/gpu. Second monitor is not effected. Problem goes away if I hard reboot(can't soft reboot since UI is obscured) or if I turn the monitor off/on. Here is my build.

Happened with most recent drivers via windows, before and after 24H2. Updated via AMD's site and no change. Changed my power settings and no change. The work around of turning it off/on would be fine but it's a combo button/cursor on the back so it is both annoying to reach around to get and worry it might become damaged long term. Trying to figure out if it's a monitor issue, a GPU issue or a Windows issue. Should I try updating the monitor firmware? New display port wire? Where can I find logs of the issue? Any info or ideas you could offer would be helpful. Thanks

LOL. So I guess this forum is dead. 99+ unanswered question and even the post with replies only have 1-2 replies. The internet is dying/dead.

If your Acer Nitro XV275U monitor displays a half-screen black issue after waking from sleep, try these troubleshooting steps: First, ensure the monitor cable is securely connected to both the monitor and the computer. If that doesn't work, try updating or reinstalling the graphics drivers, or try a different cable and port.
Here's a more detailed breakdown of potential solutions:-

1. Basic Checks:
   Cable Connection:
   Make sure the cable connecting the monitor to your computer is firmly plugged into both the monitor and the graphics card/computer.
   Different Cable/Port:
   Try a different cable (HDMI, DisplayPort) and a different port on your computer to rule out a faulty cable or port.
2. Driver Issues:
   Update Graphics Drivers:
   Outdated or corrupted graphics drivers can cause display problems. Go to the Acer website or the manufacturer of your graphics card (NVIDIA or AMD) and download the latest drivers for your specific model.
   Uninstall and Reinstall Drivers:
   If updating doesn't fix the issue, try uninstalling the current drivers from Device Manager (right-click on the Start button, select Device Manager, expand Display adapters, right-click on your graphics card, and select Uninstall device) and then reinstalling them.
3. Monitor Settings:
   Check Monitor Settings: Some monitors have specific settings that might be causing this issue, such as incorrect aspect ratio or refresh rate. Consult your monitor's manual for instructions on how to access and adjust these settings.
4. Other Possible Issues:
   Power Management Settings:
   Check your computer's power management settings to ensure that the monitor isn't being set to sleep mode too quickly. You can adjust these settings in Windows Control Panel or the Power Options settings.
   Hardware Issues:
   In rare cases, the problem might be a hardware issue with the monitor itself or the graphics card. If none of the above solutions work, you may need to contact Acer support or a qualified technician.
