^I think you meant to say HDMI is better. DVI just came out first. HDMI just uses it along with audio in a different connector. DVI Dual Link has an advantage over HDMI as it has double the bandwidth. That is why 120Hz monitors require dual link. You are pumping twice the data. 120Hz TVs do not receive 120Hz, they just refresh the display 120 time a second and do its own image processing. The image is not being updated at 120hz.
