Recommendations for a 50" (or Larger) Display?

An anonymous reader asks: "What display device should I get for a conference room? It can't be a front projection and it should be >= 50" and somewhat slim. If I go plasma, it seems like the burn-in problem could be serious if the unit is used as a monitor -- I don't want to look at either a 'Start' or 'KDE' button until the end of time. LCDs don't impress me since I can only get them in sizes of 45" or less. What about DLP? They make noise, but will it drown out a person trying to make a presentation to a room of 10-20 people? Overall, am I really stuck with a max vertical resolution of 768? Are rear projection LCD's or DLP's slim enough to not dominate a room?"
