My laptop has HD-DVD, but its resolution is like 1280 x 800. HD-DVD resolution is something like 1900 x 1220. I'm getting an HDMI to HDMI cord, but this won't make it look any better on my TV. Is there any way I can make my HDTV the actual screen of the laptop, so that nothing appears on the laptop, and the video signals are all transmitted to the TV?
