I'm in the market for an external display for my MacBook to run in clamshell mode. I realize that a MacBook can support 1920 by 1200 resolution on an external display. I'm now seeing external displays as large as 28" that have 1920 by 1200 resolution. I've read of people running 22" displays, however, I can't seem to find any "real world" experiences in this forum or elsewhere online of folks using a 28" display with their MacBooks in clamshell mode. Has anyone done it? If so, how does the display look & act? I want to get as large a monitor as possible for my MacBook, but, I don't want to sacrifice too much quality of display. Thanks for any feedback here.
