Something strange. When I use my old NVidea GTX 1060 Dual, everything is ok, even when I connect it to my receiver first and then to my main screen. 4K works fine.
As soon as I add the WX7100 next to my Nvidea video card and connect this card to the main display or to my receiver and then to my main screen I get only Full HD.
When I try to change the resolution I get a message that my screen does not support 4k.
But my receiver and main screen are both full 4k supported.
I tried to use a different cable, Display to HDMI what I need to use, same thing.
Maybe I do something wrong.
Many thanks in advance.
