If you do make the effort to use a Plasme screen as a monitor you will be very disappointed !
The quality of the picture will be c**p and any moving pictures will be eyewatering. As the above writers have said, beware of screen burns, stick to a TFD screen display, easier on the eyes. HDTV is only as good as what the broadcasters transmit, and that is not always what you think. When the broadcasters use the full bandwidth (7Mhz +) then we may notice the difference in quality.
