PC to HD TV

Looking for how to hook up a PC to a HD TV and get great results. This way, you could leverage investment in an HDTV. I have a 720p Panasonic Plasma 42" and hooking up my PC via the supplied VGA input was abysmal.

This writer has a Sharp Aquos LCD, suggests simply getting a TV that advertises compatibility with PC resolutions, and connecting using a DVI cable (since it's a digital signal). Note that full HD, or 1080p, contains 1920 x 1080 pixels. It also has some advancing tuning advice using PowerStrip software.
