hmmm,

you probably have an answer from elsewhere already, but here's a stab. When you reach that size, you leave the computer world and enter the TV world--not that you can't use an LCD panel marketed for TV as a computer monitor. But you'd have speakers and tuners to contend with, as well as a high price. I'd say check out web stores like PC Connection, TigerDirect, and Computers4Sure for ideas and prices.
