It's wacky, but does work. Repeats screens
You can de/increase Y safely.

Just FYI you can do other weird stuff. The display has 1920x1200 addressable pixels, but the sync causes the "top" to be in the bottom of the image.

Ok, I think this is my FAVORITE 96Hz!

In the screen section of your xorg.conf

   ## Set to True/False for auto stuff, False/True formanual
    Option         "nvidiaXineramaInfoOrder" "DP-4"

    Option "HorizSync"   "DP-2: 1-280; DP-4: 1-280"
    Option "VertRefresh" "DP-2: 1-280; DP-4: 1-280"

    Option         "metamodes" "DP-2: 1920x1080_96 +1920+0; DP-4: 1920x1080_144 +0+0"

    Option "ModeDebug" "true"

    Option "UseEDID" "true"
    Option "ExactModeTimingsDVI" "true"
    Option "ModeValidation" "NoMaxPClkCheck, AllowNonEdidModes"

sudo xrandr --newmode "1920_1080_108" 270 1920 1952 1968 2000 1080 1089 1094 1250 +hsync +vsync
sudo xrandr --newmode "1920_1080_96" 240 1920 1952 1968 2000 1080 1089 1094 1250 +hsync +vsync
sudo xrandr --addmode DP-2 "1920_1080_96"
sudo xrandr --addmode DP-2 "1920_1080_96"

Then use normal resolution tool to make it go.

And that should work with gdm.
