As far as I can tell the only difference is styling and backlight type. Is that correct?
I currently have one 2311H and am looking for a second monitor. It has to be IPS. This is my primary computer for general tasks including photo editing. I currently do not make enough from that one task to justify a real professional monitor. Oh how I wish... I sold my aging 19"TN to make space for this new purchase, and it cant come soon enough. It is so cramped on one screen!
I do however have a spyder 3 elite color calibrator. So whatever monitor I get will be calibrated to the best it can be.
Dell has stopped selling the old version, but there are still new units floating around. Should I pick up a new/refurb/used H version? Or go with the newer HM?
Miss-match in housing won't bother me, but if I am really unable to get the monitors to match well it will bother me!
*Edit* I should add that my primary work involves reading innumerable pages of scientific literature.
*Edit* Maybe I asked my question incorrectly. Lets try this. Is there any reason to buy the old over the new considering, that they are basically identical in price? Is there any reason that I wouldn't be able to satisfactorily color match the displays?
*Edit* Well I went with the u2311h because there are not good reviews of the u2311hm out yet!
