I am talking about computer LCD, not LCD TVs!
Right now the largest LCD you can get is a 30" from various companies. The resolution is a 16:10 widescreen 2560x1600.
The maximum resolution of one DisplayPort cable is 2560x1600, so it seems like we have reached the current end of LCD displays, however my understanding you can use multiple DisplayPort cables to aggregate bandwidth!
There means there is no real limit to the size of LCDs. Given that, what do you think is the next LCD after 30" for computers?
