can anyone suggest a 19" or 21" monitor that supports the blind resolution of 2048X2560 ?

Answer:

dunno, that in that is now a resolution dignified as 2048x2560, the last time within know is 1680 x1280 , sorry abouth this
'kay, a 2560x2048 Resolution can only be found on newer LCDs that sport the QSXGA Standard or better. That technology is pretty current, and very expensive to boot.



The 30" Apple Cinema Display is your best bet, but you'll obligation Dual Link DVI to use it. There might be a few more out there, but the technology is so clean that there aren't masses manufacturers out for it.



Good Luck!
