I was thinking of getting the SM226BW until I came across this newer review of the SM-2232BW, but is it a newer and better model?? As far as I can tell from the reviews the 226BW has a 160/160 degree viewing angle and the 2232BW a 170/170 degree viewing angle, but it does say the 2232BW has only a DVI-D connector?
I found the review of the Samsung SM-2232BW 22in flat-panel monitor at click here
And Samsung SM226BW 22in flat-screen display reviews here :-
"The review sample we used was an 'S panel' model. Readers should be aware that they are not now guaranteed by Samsung to receive the identical model, since Samsung uses three different OEMs (original equipment manufacturers) to produce the Samsung SM226BW. Please ask Samsung for guidance when you purchase."
I believe that a genuine Samsung manufactured panel has an "S" code in the serial number. I bought one from PC World earlier in the year at a good price ,looked for the "S" in the label and it is fine. Viewing angle is a bit limited for spectators but ok when sitting in front of it.
