Question: What files/settings does ColorControl change to disable dithering on AMD #343

What files/settings does ColorControl change to disable dithering on AMD?

I know old AMD GPUs supported a registry tweak like HDMI_DisableDither but that string was from atikmdag.sys which newer GPU drivers don't even ship with.

So how do you achieve disabling dithering on AMD in ColorControl?

Maassoft commented 3 months ago

ColorControl uses the ADL2 (AMD Display Library) to achieve this. You can find more info here: https://gpuopen-librariesandsdks.github.io/adl/group__DISPLAYAPI.html (See function ADL2_Display_DitherState_Set)

Btw, does the AMD controller still work properly on your end? I thought there was a user saying it was broken a while ago. I currently can't test this myself.

Yeah it works. I haven't gotten any errors. Driver 24.3.1 on RDNA2 GPU - Windows 10

And thanks a lot for the quick reply. Very helpful information!
