I hope that the solution I presented here worked for you.
Solution 1 :
Go to the link below if you are using Laptop with Intel Graphic Card.
Basically what you must do is switch from clone to single display mode.
Solution 2 :
I took the power out on the screen (the cable, don't actually click the button, just rip the cable out, as it'll force a reset, since it's memory that controls the screen can't follow without power). When it restored it automatically chose 1920x1080.
Solution 3 :
The monitor's refresh rate some how got set to 200 Hz refresh rate.
Changed the monitors refresh rate back down to 60 Hz and it fixed the problem.
Note : Before when the monitor's refresh rate was set to 200 Hz, the monitor never went over 1024x768.
After we set it down to 60 Hz, the monitor correctly went to 1920x1200.
