I own a crossover 3440x1440 95hz. I used to run it at that specification until I recently noticed that it was only running at 60hz.
After messing around with xrandr I noticed that when booting with kernel <=4.17 I was able to run it at 95hz again. Tested with Manjaro and Kubuntu 18.04 live.
I don’t know what refresh rate it was running at before kernel 4.18.9. But with 4.18.9 as well as 4.19rc4 I was only able to set it to 30 and 60 hz.
Do you guys have any idea what’s going on? Thanks for any input.
