My Setup
2 monitors:
Viewsonic ViewSonic VX2758-2KP-MHD (MAIN)
LG 27UL600-W (SECONDARY)
GPU:
AMD Sapphire 5700XT Nitro+
Radeon Software 20.4.1
OS: Windows 10 PRO 1909 x64
Both Monitors connected via DisplayPort, with freesync enabled using two of Club3D VESA Certified CAC-2068 DisplayPort to DisplayPort 1.4 cables.
When I enable a Custom resolution for the Viewsonic monitor, Windows and Radeon Software, are reporting the ColorDepth has decreased from 8bpc to 6bpc.
I tried a couple of settings in the custom resolution, but were in vain.
When creating this custom resolution, I'm just changing the refresh rate from 144 to 143 OR 142 Hz.
When I manually change the Color Depth from Radeon Software, from 6 bpc to 8bcp, both screen flashes, 8 bpc remains selected for 2-3 seconds, then the screen flashes again back to 6 bpc.
I need to use custom resolution, because this ViewSonic Monitor has an issue with flickering, and the workaround is to use a custom resolution with minus one (-1) or minus two (-2) Hz.
