I have the viewsonic va800, it has its plusses and minusis.
the big drawback is the price, and the refresh rates. for half the money i could have got a crt monitor with higher rez and almost double the refresh rates at the rez I'm running.
the big plus for me is you can get the image detail in in-game shadows and other dark areas without turning up the brightness so high as to wash out the colors.
also room lighting and open windows only give you a very slight glare. instead of bright glare and clear reflections of windows and lightbulbs behind you like you get off the glass in a crt screen.
so you don't have to turn off the lights, close the shades and basicly live in the dark like a troll to play a game.
