I recently bought an Acer GD235HZbid, which is capable of displaying up to 120Hz. I've noticed that when I have it set to 120Hz, and am viewing darker colors, especially darkish grays, there is a really faint "waving" or "rippling" of lighter color going from top to bottom. The crests of the waves are ~2 inches apart, and move somewhat slowly (maybe like, 2 or 3 "waves" per second). It seems to come and go. Sometimes I'll look at a dark background and it'll be there, then five minutes later I can look at the same thing and it'll be gone. As far as I can tell, turning down the refresh rate to 100Hz or 60Hz seems to make it go away entirely.
I tried searching for this on google, but I must be using the wrong terminology or something, because I can't find ANYTHING about this. It's not particularly detrimental to my viewing experience, but I would like to figure out what's going on. Any insight?
