grub2 - Resolution Problem Using Ubuntu on a Dell Monitor

I am having trouble running Ubuntu on a custom made desktop (some specs below). The problem is that at a certain point my monitor shuts off and gives me the message:


The current input timing is not supported by the monitor, Please
change your input timing to be 1920x1200@60Hz

Initially I was having this problem during installation, so when the first purple screen would come up I hit the down arrow and set nomodeset and added "vga=0x14d" to the end of the command. This allowed me to continue without getting the above error on my monitor. Once installation was complete I edited /etc/default/grub to include the line:


GRUB_GFXMODE=1920x1200

Then I entered:


sudo update-grub

And restarted the computer. Now when I get to the Grub screen, everything is fine but after the that I again run into the input timing error. I have tried various permutations and combinations in the edit screen but I can't seem to set the resolution properly to actually see Ubuntu once it has started up.


Relevant specifications:
Ubuntu version: 16.04
Motherboard: Asus X99-E
GPU: Nvidia GTX 1080
Monitor: Dell U2412M


EDIT: The motherboard does not have an integrated graphics card.
EDIT2: I tried following the answer for Graphics issues after/while installing Ubuntu 16.04 with NVIDIA graphics, however setting nouveau.modeset=0 at the end of the line that begins with "linux" does not work, I still get the input timing error above and if I cannot boot into Ubuntu then I am unable to install drivers.
