If its a work computer I highly doubt the graphics drivers are up to date and other things. I'll link in a min what steps you can do to test.

That's the basic troubleshooting steps.

You can also send a support ticket there if you find it dosnt help.

If you end up sending a ticket you need to also run the Support tool

http://sd.stardock.com/Support/supportToolTest/SDSupportTool.exe

Information on how/why to use it is at the bottom of the troubleshooting page.

and silly question, have you turned off/on Full screen in the graphics menu?
Also even know your monitor may support higher then 1920 x 1080, are the monitors actually set higher then that?

And since its a work computer, do u have full admin permissions to do things? I can imagine if you don't certain things might be preventing the game from working correctly.
