  • Ok so setting it to limited range appears to have been a fluke because my log of further troubleshooting makes it evident.

    Below i am pasting a text log of further troubleshooting tests i did, it does seem to suggest a faulty HDMI cable, Maybe the second HDMI cable i used to test twice also was faulty

    i’m going to try and see if i can find another HDMI cable to test to see if that gives me any more information

    but I’m wondering why disabling the monitor in device manager stops the issue if it is a faulty HDMI cable

    Monitor resolution test:
    
    PC Resolutions:
    
    800x600:
    
    144hz, 8bpc, Full Dynamic Range: Working at current time
    *does not scale to full screen size and has black borders
    60HZ,  8bpc, Full Dynamic Range: Working at current time
    *With this one monitor or windows or gpu scales to the full screen size
    60HZ,  10bpc, Full Dynamic Range: Working at current time
    *monitor or windows or gpu scales to the full screen size
    60HZ,  12bpc, Full Dynamic Range: Working at current timr
    *monitor or windows scales to the full screen size
    
    1024x768:
    
    144hz, 8bpc, Full Dynamic Range: Working at current time
    *Does not scale to full screen size
    
    60Hz, 12bpc, Full Dynamic Range: Working at current time
    * Scales to full screen size
    
    1152x864:
    
    144hz, 8bpc, Full Dyanimc Range: Working at current time
    *Does not scale to full screen size
    
    ========
    
    Later Steps:
    
    2560x1440 at 12bpc 60hz full dynamic range works, so does 144hz 8bpc but this is after going through various resolutions in increasing length as documented in this text document
    
    turning monitor off and on at this point in time does not reintroduce issue
    
    next step is unplugging and re-plugging hdmi cable
    
    re-plugging hdmi cable after approximatly 30 seconds, this reintroduces issue, changing to limited in nvidia control panel does not fix this
    
    changing to 800x600 pc resolution after unplugging and replugging hdmi cable with nvidia control panel set at 144hz, 8bpc and limited dynamic range does not fix issue
    
    then changing refresh rate to 60hz does not fix issue
    
    setting to 1440x2560 before rebooting to see if rebooting does something
    
    after laptop the nvidia control panel resolution was at 800x600 and the issue wasnt there but changed to 1440x2560 at 144hz 8bpc and issue started
    
    disabling the monitor at this point in time in the device manager still fixes the problem (but breaks windows nightlight from working on external monitor as i have personally noticed when first trying to use windows nightlight after disabling the monitor in the device manager)
    
    setting to 60hz, 8bpc 800x600 resolution
    
    enabled in device manager, monitor blanks once but issue goes away
    
    going to unplug and re-plug cable
    
    re-plugged hdmi cable after 30 seconds, monitor blanks once but is stable and issue is gone
    
    noted that output dynamic range in nvidia control panel is still set to limited
    
    going to set to full dynamic range
    
    at 8bpc, 60hz 800x600 at full dynamic resolution issue does not present itself
    
    going to unplug and re-plug cable while the display resolution settings remain the same in nvidia control panel
    
    plugging in cable after aproximatly 30 seconds, monitor blanks once but issue does not present itself
    


  • 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
