the lcd i am looking at is a sony 18.1" and can do up to 1600x1200 ... it's interesting because it has a separate media engine... its a little box that sits off to the side... makes for an incredibly thin monitor... i too wonder tho if it can handle being run 20+ hours a day at max resolution... and how that'll be on my eyes...
here's the link if anyone is interested:
