I have a display that supports 280 Hz and although I'm limited to an old Intel HD610 via HDMI, **on Windows I'm able to set the refresh rate up to 120 Hz** (checked on display menu), but on Linux I can only go to 99 Hz maximum.
What I'm doing:
cvt 1920 1080 120
Which prints:
# 1920x1080 119.93 Hz (CVT) hsync: 139.12 kHz; pclk: 369.50 MHz
Modeline "1920x1080_120.00" 369.50 1920 2080 2288 2656 1080 1083 1088 1160 -hsync +vsync
Then:
xrandr --newmode "1920x1080_120.00" 369.50 1920 2080 2288 2656 1080 1083 1088 1160 -hsync +vsync
And:
xrandr --addmode HDMI1 1920x1080_120.00
Finally, when I try to set this custom refresh rate (via Xfce Display app), nothing happens; it goes back to the previous refresh rate. I did the same process with 90 Hz and it worked, but that's the maximum I could go.
My xorg (v1.20.10) log contains this interesting information:
