"hook up to a laptop via DVI? The TV does not have a DVI input"
No, this will never happen. But since you have HDMI have you thought of a laptop with HDMI output? And before you think about a VGA to HDMI converter box did you price it out?
Is it possible to use a 52" LCD TV as a monitor which I can hook up to a laptop via DVI? The TV does not have a DVI input only HDMI and RGB. Can DVI out be converted to RGB or HDMI and would this work? HELP!
