Duplicating Displays Only When Needed

post #1 of 4
Thread Starter 
I don't know if this belongs here or in a Windows 7 section, but I have my TV hooked up to a 21 in Acer as my main display, and then through my DVI/HDMI connector to my Phillips TV. I only use the TV display when I'm using my PC as a movie player. Aside from that, my TV input is set to the PS3 or cable box.

Is my graphics card still doing the processing to display two displays, even when my tv is off or on another input? I do notice when I switch to my PC input, the monitor on my desk will flicker, almost like it's changing, and will do it again when the TV is turned off or the input is changed.

I just want to make sure when I'm play games on my single monitor, that my graphics card isn't doing more work than it needs to. But I also want to make it as automatic as possible to turn the TV to pc input from the couch and it be all set up, so as my GF and friends can use it even if I'm not around.

Any help would be appreciated, thanks!

Change back to single display in a jiffy.
From my view the GPU still renders both screens even when it's off since it still allows for windows and applications to move to the second part of the desktop with or without the second monitor powered on.

Right click your background in Windows 7 > Screen Resolution, Only 1 display should be selected, it will use that display and only that one, the picture will switch to whatever you select. So, if you're doing it properly it's not processing 2 displays.

I always utilize this method rather than spanning the desktop across 2 displays or cloning it on 2.

I also watch BluRay movies/video on my HDTV via HDMI.
