Hi
Feartech,
I tried these 2 versions of settings which I found on GitHub for my model and unfortunately I still do not see resolution option higher than 1080p in MacOS settings included turned off mirroring. I also tried them on 3 MacOS versions Monterey, Big Sur, Ventura.
For some reason on 1080p the picture was a bit better on Big Sur and Ventura than on Monterey.
I would say the best on Ventura then Big Sur then Monterey.
I also tried several apps like RDM to set a higher resolution but they looked like a fake upconverted video - even worse than 1080p.
I did not manage to set a custom resolution using them though, for example those I tested and know will work good on my machine in Linux and Windows such as
3840x2160
2048x1152
4096x2160
2048x1152 would be actually enough for me
