I have a Radeon HD 5250 that has dual output. In a particular game that I'm playing, it's choppy even at the absolute lowest graphics settings and resolution. During that time, my second display is completely active as though I wasn't playing a full screen game on the primary monitor.
Would disabling the secondary output improve video performance on the primary output?
If so, then is there an application for Windows 7 that will easily and temporarily disable the second monitor? I know I could go into the control panel to disable it, but then it shrinks the size of my desktop, potentially moving icons around, and it will shift all my open windows to the primary monitor, etc. It seems like a problem somebody else would have solved already.
