Did you tweak the driver or have to disable any dithering too?
Out of the box, temporal dithering is disabled on Windows 10 22H2 and Windows 11 24H2 when using the RX6600. I can’t say for sure about spatial dithering, but I believe it might be present in the DITHERING: DRIVER_DEFAULT mode [ColorControl], since when switching to DITHERING: DISABLED [ColorControl] , only 96.08% of the pixels remain unchanged on the test image—the rest change their color.
I don't use Windows 11 regularly, so I can't comment on how comfortable it is for the eyes when using the RX6600.
In ColorControl, I set DITHERING to DISABLED. In my graphics card settings, color depth is set to 8-bit, RGB 4:4:4. The driver version is Adrenalin 24.12.1.
How did you find out about the refresh rate change?
I stumbled upon this completely by accident while experimenting.
I assume thats specific to your tv?
yes
I forgot what motherboard are you running too?
Motherboard: Z390 AORUS MASTER G2 Edition (rev. 1.0); BIOS F20; Resizable BAR enabled; Compatibility Support Module disabled.
