How well does a 30" LCD work as a PC monitor? I'm thinking about placing the Samsung LTM295W on the wall behind my desk to use as a computer monitor. The unit would also function as an HDTV from 9 feet away on a sofa up against the wall opposite the desk. I've read that the LTM295W performs well as a PC monitor when using the DVI input at the native 1280x768 resolution. Is text on the screen reasonably sharp (i.e. not fuzzy) at this resolution?
