I use two identical GPUs and am still confused after reading the guide | Lossless Scaling | Page 1

My PC is an unchanged dual GPU setup from 2017, I just have pretty good hardware and happen to play a lot of games that have native crossfire support. I have two radeon RX vegas. I also run win11 and use two monitors of different resolutions (1440p and 1080p), sometimes my tv as well (1080p). I usually run games on the larger monitor of course, sometimes the tv.

I am still a little confused and not sure if I've set up mgpu support correctly after reading the directions. It's hard for me to tell which GPU is which in the settings, and I think some of them are showing up differently because both GPUs are identical. I haven't had a ton of time to test things out, but I was hoping somebody might be able to help clarify my issue.

First GPU in the list in LS is the one connected to your main monitor

They probably mean Windows settings

In LS, just selecting Auto is good enough

If you connect all displays to one GPU, Windows should make the other one "power saving". Choose that
