Even after a fresh install, I’m getting what appears to be a random White Screen Flash either on desktop or in gaming when HDR & VRR is enabled. It is inconsistent but frequent enough to be annoying LOL.
I know this was a problem about 6 months ago, but I was under the impression this has been solved.
Are others still reporting this is an issue? or what troubleshooting steps should I take?… considering I want both HDR and VRR enabled.
Troubleshooting Steps Taken:
Disabled LACT undervolt
Color Accuracy - Perfer Efficiency
10bit and 8 Bit
Refresh Rate: 60Hz, 120Hz & 165Hz
Swapped DP cable - DP80
Disabled eGPU on AMD 7800x3D CPU
Monitor: ASUS XG32UCWG 165Hz 10bit 4k Freesync (VRR 48-165)
This example is quite extreme. I only observe a single flash randomly that can span minutes to hours. Very hard to point the issue. Trialing a few now and will report back my findings.
Looks like I may have found the problem….. current Asus XG32UCWG monitor firmware MCM301 was recently updated with MCM104 (MCM304 - once flashed). Reported that it updated the VCP Protocol for HDR flickering.
”Flicker-Free HDR: Optimized DisplayWidget Center (VCP protocol) to eliminate screen flickering during HDR transitions.”
A few flash attempts later (8Gb FAT32 USB Drive - 16Gb USB Drive did not work) look like things are stable post update. So far testing seems stable at 164Hz @4K
