I recently bought a Toshiba Qosmio about a month ago. I have downloaded all the latest Intel Display Drivers and the latest Nvidia 770M drivers as well. I have been playing Diablo3, Starcraft2, WoW on fullscreen on the laptop for a month with no problems. Until now....
One night I hooked up my 23" LCD in the VGA and 32" TV in the HDMI and played around with Diablo3 and Starcraft2 on the monitor setup. I never ran WoW.
After playing around with the setup I disconnected everything. Upon starting Diablo3 again I got a error window "Graphics Error" "Click to retry creating D3D device"
Game would not start at all. I had to look around the Blizzard forums to actually go into the config file and switch to Windowed (Fullscreen). The game then runs fine and when I switch back to Fullscreen, crash and unable to start the game again. This also happens to my Starcraft 2 as well. Now I have to play this game in Windowed (Fullscreen).
But I never opened any other games when I did the monitor/TV setup. So when I run WoW I am to play Fullscreen or Windowed and able to switch between the two in the game with no problems. Same goes for all the Steam games, I am able to switch between the modes.
Just Diablo3 and Starcraft2 is giving me these issues. I have reinstalled the game numerous times. Removed config files. Even run their Repair Tool. With no resolution.
Does anybody have any ideas on how to get back the ability to switch these two games back to Fullscreen mode.
Can I do a reinstall on my DirectX or can I reset it or something?
Only option I see at this point is formatting.
 
Solution
yes you can reinstall your DirectX, when your right click your desktop and open screen resolution does it still show the other screen there? if it does disable it

Can you reinstall DirectX on Windows 8? If you can how? Because I have read on other posts that you can not on Windows 7 so I assume that would carry over to Windows 8
