There's no DVI connection, but there is HDMI. HDMI is just DVI plus sound, so you can convert back and forth between HDMI and DVI with absolutely no change in the picture. They're completely equivalent in this respect. The monitor comes with a DVI to HDMI cable, so if you want to use this with a PC, you plug the DVI side of the cable into your video card and the HDMI side into the monitor. No need to buy anything else or to use VGA.
Thanks bootstrap, that was a great explanation and really cleared it up for me This monitor is $599.99 at Future Shop, I'm going to get it this weekend.
