Are you using an integrated video card or an aftermarket video card? If an aftermarket card, then which brand and how much ram? Which type of video are you attempting to utilize Open GL or Direct?
What is the manufacture of the computer you are using? If you are using a laptop, then are you using a docking station?
What brand/type of monitors are you using?
I have an HP Z600 Workstation with tons of RAM and Xeon E5520 processor. My workstation would do the same thing until I upgraded my monitors from Acer 22's to Dell E2715H 27" monitors. I also have an aftermarket AMD Radeon 3400HD 3gb Ram graphics card and had to update the driver in order to allow ArcGIS PRO to run as it was intended...sounds goofy, but give it a try, as it made the difference for me.
BTW - typically when someone asks for help...they should try not to be rude to those attempting to help them out... just saying!
