OK, hope my title explained everything, but just in case.
I am currently running 3 x 1080p monitors in portrait eyefinity at 3840x1920, and would like to know if it is possible to run the vertical at 1600, 1440 or whatever with black borders on the bottom and top. I tried using centered timings but no luck.
The reason for this is because i don't like 5760x1080, but i also find 3840x1920 to not be wide enough. Any solution would be much appreciated.
