My screen supports 10-bit HDR, so I set the Nvidia driver to output 10-bit and enabled HDR in Windows. The Advanced display settings show as '10-bit' (the screen is actually 8-bit+FRC) but 10-bit output support is there.
New graphics driver today, booted in Safe mode, did the DDR, installed new drivers. The same process I've always done with new GPU drivers.
Restarted - no 10-bit support in the Nvidia driver, although HDR is available in Windows. The Advanced display now shows '8-bit plus dithering'
So, thinking it's the new drivers, I restored a system image I made this morning. Same problem, no 10-bit working.
Uninstalled the new AMD chipset driver, same problem.
I don't get what's happened here, if the driver was bad then the known-working backup should still work?
So I tried a clean install on a different drive, same hardware. 10-bit? All working. Updated chipset and Nvidia drivers, still working. Exactly the same Windows build, drivers and hardware (22621.105)
Clearly NOT a hardware problem but what could have happened here? Something must have changed before the daily image backup yesterday morning that I'm not aware of but I'm at a loss why I've suddenly lost 10-bit graphics support
