Just yesterday switched to Fedora 28 (mesa 18.0.5). I have 3 monitors and only the AOC has it’s full range of refresh rate.
The most infuriating is my main monitor crossover 3412um 3440x1440 95hz which is only going up to 60hz. Any attempt to go over 60hz results in
xrandr: Configure crtc 0 failed except 95hz which results in a black screen and after that flashing of my AOC monitor.
cvt resutls for 3440 1440 95:
# 3440x1440 94.95 Hz (CVT) hsync: 144.61 kHz; pclk: 689.50 MHz Modeline "3440x1440_95.00" 689.50 3440 3728 4104 4768 1440 1443 1453 1523 -hsync +vsync
I had the idea copying windows setting over to linux because all three monitors work there. But the numbers are completely different. Nowhere do I have v./h. porch or v./h. sync width on linux. Only thing is the G.Pixel Clock is 503.60 and in linux I think it’s the first number 689.50.
Everything I tried resulted in the
xrandr: Configure crtc 0 failed error.
This is a dealbreaker. I cannot look at this mess of 60hz while using/playing at 95hz for over a year now. Would hugely appreciated help.
