I got an GN246HLBbid 144Hz Monitor. Running on Archlinux.

The GNOME System Config tool doesnt detect its 144Hz Feature.

I tried the following:

Generatate a Modeline by doing:

 cvt 1920 1080 144

It resulted in:

# 1920x1080 143.88 Hz (CVT) hsync: 169.35 kHz; pclk: 452.50 MHz
Modeline "1920x1080_144.00"  452.50  1920 2088 2296 2672  1080 1083 1088 1177 -hsync +vsync


xrandr --addmode "1920x1080_144.00" 452.50  1920 2088 2296 2672  1080 1083 1088 1177 -hsync +vsync

And finally:

xrandr --output HDMI-0 --mode "1920x1080_144.00"

But the weird issue comes here: xrandr says it does not "find" the mode. I have no idea why.

Any Ideas on how to get the 144Hz Feature up and running?

    Thanks, Issue is fixed. I didnt know, that HDMI is not capable of that Frame Rate. DVI fixed it. Dumb be xd – Peter Parker Jan 28 '17 at 16:46
  • Thanks for the update. It would great if you would provide an answer to your question, so that the next guy along will know to look at that. – Stephen Rauch Jan 28 '17 at 16:56

OK Issue found.

I tried to drive the Monitor with 1920x1080@144FPS over HDMI whats not supported by HDMI.

Just to try, I switched to DVI. Since then it works.

A DVI-Duallink Cable is required, but It came with the Monitor.
