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.

If you move the cursor above them, the tooltip will show what they do. Probably they're also listed in the help file.

Yeah I did see that but they are pretty vague. Also is it being enabled by default just happen for any lcd display or did the driver run some kind of auto detect to see what display it was and acted accordingly.

It's about Reduced Blanking if my memory serves me right, which a standard that most monitors supports from going about a decade back. But it's good to have the option in there just in case. Checking it turns Reduced Blanking off which is not ideal for a flat panel but in practice either mode would not be a problem on modern systems. It could become necessary with some DVI interconnect thrown into the mix, like an older KVM switch for instance.
