Hi, I can test it, more or less if the card does work at 4k resolution, or at least if don’t work
more or less because I have just a web presenter that can accept 4k signal, so I can just see the four output one by one, not simultaneously
so it is not a proper test but probably a good indication
also my card is connected with half of the lanes (four instead of eight)
but for that I will try with just one f+k at first and then the double f+k after.
