I have been using my PG278Q for a week and love it; but I went to the store today and when I got back and woke My PC up it said G-Sync was disabled. Now G-sync is no longer in the nvidia control panel. Everything went smooth when I first set it up, I just checked the G-Sync box and everything worked. I reset everything and re installed 340.52 drivers. I'm at 2560X1440 at 144 hz. I hope the G-sync chip didn't burn out. Any help would be greatly appreciated.
