I would need more information in regards to your system configuration:
Which version of Windows do you have?
Also, the exact processor model and the graphics controller:
Click the Windows icon, and then right-click Computer .
Select Properties .
Find System Type on the Properties window, and then note the processor model.
I have windows 7 on a Dell Vostro 3500, Intel (R) HD Graphics, and my processor is: Intel(R) Core(TM) i3 CPU M 350 @ 2.27 GHz 2.26 GHz.
2 GB (Ram)
Screen resolution on my computer is 1366 x 768. The monitor I'm running is 1920 x 1080.
Thanks for your help!
Can you send a screen shot of the graphics control panel? Multi monitor settings picture would be great.
