which might work.
I'd suggest loading it in Phoenix EDID Designer and checking that the details it shows match what the manual says your monitor is capable of.
Make sure you've exhausted every other possibility before you start messing around with the monitor EDID, because there is plenty of potential for screwing things up permanently. That said, I've just managed to get my Samsung B2330H working properly for the first time by altering its EDID myself.
I believe that the current graphics card drivers from both ATI and Nvidia let you override the resolutions specified in the EDID, so you might want to give that a go first.
Googling "Samsung wrong EDID" does suggest that quite a few people have run into similar problems from this maker. It would be interesting to know whether that's just lousy quality control or something a bit more complicated going wrong.
