I tried it out for a while and I think a new feature? is that you can control de brightness of the monitor through Plasma. Cool for one monitor but I have 2 and one is brighter than the other at a given brightness %, so it got a bit annoying. I didn’t look further into it but when 6.1 is released on Fedora I will probably need to.

Additionally the SDR colors when HDR is turned on looked better overall. Better than Windows was able to do even. Awesome stuff
