Opened a topic with the exact same question about a week ago. The 226bw seems to be a good choice, though I've been reading some more about the screen but I also hear some negative things. It seems the colors arnt that great and backlight bleeding seems to be pretty bad. That there still is the A, C and S panel problem. Unless you get a S one (made by samsung) IQ apparantly is pretty much crap. You also got the 226cw which is said to always have a S panel but that still seems to have some issues. Your best bet is probably the samsung 2232bw (
not the 223bw) It has a newer panel that the 226 series, better viewing angle and better colors and less backlight bleeding and its the same price. I will probably get the 2232bw.
