Not to thead crap but:
Max / Optimal resolution: 1600x1200 @ 68 Hz / 1280x1024 @ 75 Hz
It can't even do a good refresh rate at standard 19" resolution. 1024 res will look too pixelish on such a big screen monitor (I have 19" sony) and anything below 85hz is too flickery for me especially on white canvas like when you're typing a letter in word or something like that. Low refresh rate can strain your eyes and cause head ache. If it was me I would pay a little more and go for monitor that can do 85hz (minimum, prefferably even higher) @ 1280x1024 if it's a 19" monitor, and 85@ 1600x1200 if it's a 21" monitor.
Refresh rate is also important if you're a gamer, not just for desktop resolution. For example, if you have top of the line 3d card like new Radeon Pro cards ect. you will not reap full benefits of such a powerful card due to low refresh rate. Every FPS game benefits from higher resolution, but the higher res you go, the lower refhresh rate you have to setle for. Flicker from 75hz is not noticable in colorfull games, it only realy stands out on white, but what it will do is limit that monster video card of yours to only 75 frames per second. Now for me, I haven't experienced with higher frames per second than 85 since 85fps @ 1280 res is pretty damn smooth for me, but I experimented limiting frames per second in FPS game from 85 to 60 and I could immideatly tell my turning was jumpy and the thing just didn't run as smooth. So for me, 85fps in games is the minimum I shoot for. I haven't experimented with even higher frames per second in games, mainly because I would then have to lower my resolution, but I've heard some people say they can even tell the difference in smoothness between 120fps and 90. You can say that you can disable vsync and your video card will not be limited any more, but it doesn't matter in this case cus even though your video card will be cranking out hundreds of frames per second you will only see 75 of them since your monitor will only be able to redraw its surface 75 times per second. Plus, you will have to put up with what is called tearing in your games which happen when vsync is off and your video card refreshes frame buffer while your monitor is still trying to draw old frame so you will see lines in your picture running accross the monitor where picture doesn't match cus part of it is old frame and part of it is new frame.
