The 1280x1024, 1024x768, 600x600, and 640x480 resolutions are all supported in that the screen never turns black. But this does not mean they are all to be recommended. Far from it. You realize you are always more or less dependent on the monitor's native resolution. The quality in 640x480 is reminiscent of the early games for PC. It's all pixels and blurring, the characters have to be worked out because they are not actually legible. 800x600 is not much better. It is only when you reach 1024x768 that things become acceptable.
Unreal Tournament 2003
Forget it, this monitor is just not for Unreal. The afterglow is dreadful - everything proliferates on screen at the tiniest movement. None of the resolutions available will do. Unrealers of the world, don't waste your time!
Return To Castle Wolfenstein
It's playable, but mind the stairs. Wolfenstein is not quite so nerve-wracking as Unreal. The walls are not too clear when you run, but on the whole the result is not too bad. It's only when you climb the stairs that the decor moves, and that can bug you. Happily, it doesn't last too long.
GTA: Vice City
The picture is superb, the colors really flash, the soundtrack music and story are as crazy as ever. But that has nothing to do with the monitor. Here again you have to put up with ghosting on the characters when they move. But at least it doesn't jump all over the place, so the game is perfectly playable. True, it would be better on other monitors, but it's still pretty good.
Command & Conquer: Generals
It's impossible to play C&C in 1280, because there is no 1280. And forget 800x600, it ruins the game. However, 1024x1024 and 1152x864 are all right. The edges of objects are tidy and the details clear enough. But the afterglow is still there and, as C&C players well know, in this game you have to rush all over the screen. So be prepared for a lot of blurring.
Here we get much the same effect as in games: image ghosting in fast movements and blurring in slow ones. This is pretty unpleasant when you are close up to the screen, less so when you watch from a distance of over a meter. If the film is absorbing, you will soon forget the afterglow. If not, you may find yourself getting annoyed.
