You probably want something like: Section "Monitor" Identifier "HDMI-2" Modeline "1600x1200_60.00" 161.00 1600 1712 1880 2160 1200 1203 1207 1245 -hsync +vsync Option "PreferredMode" "1600x1200_60.00" EndSection The Identifier should be the port that the display is actually connected to, which you can find out with xrandr. And obviously don't use those specific line timings, but use /usr/X11R6/bin/gtf or /usr/X11R6/bin/cvt to generate suitable timings for your hardware.
