I am using cable marked as a high speed HDMI cable so I do not suspect this to be an issue (+ as I said, it worked before Win10 20H2 update). The issue is that before I installed Windows 10 20H2 update, everything worked just fine (I mean, when I selected only my external monitor and did not use it together with my built-in laptop monitor, I was able to set 3440x1440 resolution just fine).
The intel GPU used is Intel UHD Graphics 630. Hi, I am struggling with setting up the resolution for my widescreen monitor iiyama g-master GB83466WQSU 34'' when connected to my laptop MSI GF-63 8RD.
