Win 7 home 64 bit. Running this graphics card http://www.newegg.com/Product/Product.aspx?Item=N82E168... I have a 720P Plasma attached to the DVI output for HTPC, and a 1024 x 780 LCD flat panel connected to the VGA output on the desktop for general use. Running Catalyst 2012.0928.1532.26508. Displays are set to "clone", not "extend desktop". Is there anyway with this setup to get BOTH monitors to be full screen at the same time?
Been a while since I cloned a desktop, but I believe it requires that both screens be running at the same resolution, so odds are it's dumbing down the plasma to match the LCD. If this is indeed the case, I do not believe that you can accomplish what you're trying to achieve using clone as it's going to default to the lesser of the two resolutions for both screens.
I guess the bottom line is whether or not there is any way to run 2 monitors of different resolutions simultaneously, with each getting the vid signal at their native resolution (1024 x 768 for the LCD, 1280 x 720 for the Plasma)?
