What I've noticed is IF you don't adjust the screen(s) alignment up and down then you don't get the Select how you want to resize desktop Triangle and then you don't get bezel compensation.

So, when the alignment screen comes up, play with it and move on. I click through the resize section. See if that helps.

Já EF neprovozuju, tudíž to nemám jak vyzkoušet.
