Basically, I've done all of the correct steps in creating the resolution for myself...
$ xrandr --newmode "1824x1036_60.00" a bunch of number -hsync +vsync
(I'm on another computer so I can't copy and paste ^)
It all works fine, but it adds that particular resolution to the table contents "DVI-D-0" when I'm actually using HDMI. So when I attempt to change the resolution via xrandr on my HDMI monitor, it doesn't know what I'm referring to by "1824x1036_60.00". Any help would be appreciated! :)
P.S The resolution is weird because its a weird monitor. It has no native.
