Oh gosh, thank you for creating this post! I was losing my mind when my Repbulic of Gamers Asus began getting this incredibly washed out appearance after 5 years of no trouble.  Don't know when that splendid utility decided to start making changes, but I was convinced my screen or some other hardware was dying.  Now if I can only figure out why I've got no audio all of a sudden.  You rock my friend.
