What is it? It is always checked on by default when I install a driver/catalyst on both my R7970 and old HD6970 which is plugged into an ASUS 23 inch monitor running at native 1920 x 1080 60 hz with what I think is a single link DVI connector. If I uncheck it the screen goes black and refreshes and I notice no change in anything with it on or off. I was just curious as to what it actually does.
Also curious about the setting right above it...which is always unchecked by default.
