How to set display refresh rate to 120+ Hz via HDMI?

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:
Code:cvt 1920 1080 120Which prints:
Code:# 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 +vsyncThen:
Code:xrandr --newmode "1920x1080_120.00" 369.50 1920 2080 2288 2656 1080 1083 1088 1160 -hsync +vsyncAnd:
Code:xrandr --addmode HDMI1 1920x1080_120.00Finally, 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 99 Hz and it worked, but that's the maximum I could go.

My xorg (v1.20.10) log contains this interesting information:
