Samsung 245BW won't display 1920 x 1200

Just purchased a new 24" Samsung monitor (245BW). I can get an image OK, but can't select a resolution above 1680 x 1050. After looking through some other posts on this forum, I used SwitchResX to take a look at the monitor's EDID. Looks to me like it's reporting specs for some kind of 22" monitor. (I'll attach the EDID in a second post). I've heard scattered reports of other people having problems with bad EDIDs in Samsung monitors. Anyone else able to use this display successfully? Am I just one of the unlucky ones? Is there anything I can do to get this monitor to display at its native res?

Thanks!

PowerBook G4 15-inch 1.67, Mac OS X (10.4.11)

You are right. The EDID in that monitor is wrong. It is self-identifying to the Mac as a wide SXGA+ monitor (WSXGA+ = 1680 x 1050) and not a WUXGA monitor as it should be. You could build a custom resolution with SwitchRes X. But you might as well just go get your money back instead because the lack of the correct plug-and-display driver in this monitor will haunt it and its user for as long as this monitor is around.
