I have been noticing a trend lately when I go to see clients. Everyone seems to think that a flat panel display is the better tool for the job in conference or meeting rooms. I'm not sure if this is unique to the Tampa-St.Pete area or if it's nationwide.
While in some cases a flat panel display may be the better choice, in many cases it is not. In a very small meeting room, say 6-8 people I think you could get away with a flat panel comfortably. Even then, I wouldn't consider anything less than 50 inches but preferably 52"-60". This also depends what the display is going to be used for. For example, a Power Point presentation with large graphics could get away with a smaller display than a meeting where you might be looking at Excel spreadsheets.
