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

    Disabling the device might make windows send “safe” resolution, refresh rate, bit depth, HDR etc

    Its definitely not windows sending a safe resolution and / or refresh rate, i checked the monitor OSD to confirm this

    HDR works fine

    I discovered that the monitor is working fine without disabling it in device manager if i select a limited range under “Output dynamic range” in the NVIDIA control panel, i have tested this in 8, 10 & 12bpc and at 60, 120 & 144hz, i am running at the native resolution for the monitor which is 2560 x 1440 so something doesn’t like the full range

    im going to check again at lower resolutions and full range to see if i can rule out a HDMI bandwidth issue

    and if this helps

    the hdmi cables im using used to be used for a TV
