No, LED is just more energy efficient than CCFL, and doesn't require the warm up cycle that CCFL does (short enough it really won't matter). CCFL can actually run brighter than LED's.Ok I understand now. So LED just means pretty much a brighter screen? but what I really want is IPS? The Mac Pro came with the 20" ACD, its just not bright enough for me. picture looks great tho. Also would you suggest a 512mb car or 1gb card? would I notice the difference between them if I dont do gaming or editing. I just watch videos pretty much. thank you.
In terms of an IPS panel, your usage description here doesn't have a technical need for it (i.e. color accuracy), though they are easier on the eyes and generally speaking, preferable to TN panels (VA panel based monitor may be a good compromise, as TN's the worst out there, VA is in the middle, and IPS "...is the one that rules them all"
If all you're doing is watching video, I'm with allupons on this one; make sure your current card can't do 1080P before you swap it out, as IIRC, it should be able to do that smoothly on a 24" monitor.
