i'm using a 34" LG UltraWide with 3440x1440 and 2x a 27" LG 4k Monitor with 3840x2160 (which obviously also would run on 2560x1440).
My plan was now, to create an eyefinity group with 8560x1440 (2560-3440-2560 x 1440).
But this doesn't work.
Every time i create the eyefinity group, i can only manage to get a resolution of
11520x2160 (3x3840x2160) if i "fit" or "stretch" the group,
7680x1440 (3x2560x1440) if i use "fill" for the group.
So the "best" solution is the second one, but the picture on the UW is stretched with this setting.
I start with all 3 monitors seperated but the Desktop is expanded to the 4k displays on the side. It doesn't change anything if i set the 4k displays to 3840x2160 or 2560x1440. Everytime i active Eyefinity, i have to choose one display. It doesn't matter if i chose one of the 4k or the UW. The 4k Displays are always set back to its max resolution of 3840x2160 and that seems to be the problem. But after creating the eyefinity group i can't change the resolution of the seperate displays on it's on (which is obvious).
I found this blog entry Mixed resolution Eyefinity
It's a bit older, but it's more or less the same setup as mine, with the difference, that every monitor is running on 1080 and mine have different heights (2160 and 1440) but a fitting resolution would be possible.
Is there any solution to my problem? Or would this only work, if i would use 27" 2560x1440 monitors with the UW?
