Mostly any LCD you can find will be able to be used as a monitor. It's now a standard norm that they have DVI, HDMI, VGA, etc. inputs on them, enabling them to double as a computer monitor. You probably won't find just a soul monitor that big, they will be equipped with tuners, but will probably cheaper than you could find a pure LCD monitor in that size. Best Buy, Circuit City, Ultimate Electronics, even Wal-Mart and Target's models should be adequate displays. :D Good luck!
