I bought a new external monitor recently and have had the issue of an intermittent display signal
Disabling the monitor in device manager fixes the issue and the monitor works fine when disabled so it’s highly likely its some weird software issue but I’d like to find a proper fix for it
I am able to get it to have constant display signal by chance sometimes without disabling the display in device manager but turning off the external display brings back the issue when I turn it back on and it reconnects
OS: Windows 11
Display: Lenovo G27QC-30 with Lenovo’s drivers installed *have tried with Microsoft drivers and run into the same issue
Have already tried uninstalling and reinstalling monitor on device manager and reinstalling drivers and that hasn’t fixed the issue
Also have already tried using display driver uninstaller to clean install graphics drivers
Edit:
the events tab in windows device manager for the monitor properties does show this error sometimes:
Device not started (monitor)
Device DISPLAY\LEN66F4\5&3287afbc&1&UID4352 had a problem starting.
Driver Name: oem64.inf Class Guid: {4d36e96e-e325-11ce-bfc1-08002be10318} Service: monitor Lower Filters: Upper Filters: Problem: 0x0 Problem Status: 0xC00000E5
Edit 2:
The monitor will work fine once if i restart my laptop but disabling and re=enabling in device manager causes the problem
Commenting on my new main account as this was posted on my lemmy.world account before I switched to lemm.ee
The issue was likely DDC/CI but I can’t say for certain, I’m 90% sure that’s what was causing it but the 10% is the chance an update somewhere fixed it
The display works fine with DDC/CI off but I’m too scared to test it again to confirm it was DDC/CI that was causing the issue
I’m just sharing this for future reference for anyone that comes across my post in the future with a similar issue
