I've been having problems with the monitor displaying an Out Of Range message or just a plain black screen whenever I try to load certain games in full screen with gsync enabled (CS:GO, Left 4 Dead 2). The problem doesn't happen all the time but it seems like a fairly widespread issue and ASUS is claiming it is an G-SYNC Driver problem.
For now I find that disabling G-SYNC resolves this issue for me.
