Hello, ive had my XL2420t for about a month now and it has been great.
I have been having some minor issues with this monitor since i got it. if i enable instant mode i notice that it causes horizontal lines to appear on the screen. these lines are not extremely visible but they are there, this only happens when i use a 120hz signal. if I turn instant mode off and turn it back on it usually goes away but comes back every time the monitor is turned on

Also, having the AMA feature on causes artifacts or "flickering pixels" in some applications. example: when I open EVGA precision x I can see a few pixels flickering all over the application window but as soon as I turn off AMA, they disappear. the only way I have been able to maintain a perfect picture is to have AMA off, instant mode has to be turned off and then back on to eliminate the horizontal "lines." keeping instant mode off actually creates some artifacts as well as AMA.
The artifacts only occur on certain applications which is weird. I can take a snapshot of EVGA Precision and the pixels still bounce around the picture so it has something to do with the colors. this also happens in SC2.
does anyone else have this problem? should i get it RMA'd? im afraid the problem wont be resolved if i do.
