Well, supposedly HDMI should 'look' better than DVI, but on a computer screen playing computer games, there's really not much difference. You can carry sound through the HDMI cable whereas you cannot with a DVI AFAIK. I've been out of the loop for too long.
"DVI and HDMI are exactly the same as one another, image-quality-wise. The principal differences are that HDMI carries audio as well as video, and uses a different type of connector, but both use the same encoding scheme, and that's why a DVI source can be connected to an HDMI monitor, or vice versa, with a DVI/HDMI cable, with no intervening converter box."
So I'm going to get the GTX 580 very soon and realized that it has 2 DVI and 1 HDMI input. Is the HDMI better quality than the DVI? Does 1 have any advantages over the other?
Thanks for any help.
Be aware that many HDMI TVs don't have the DV interface. I'm in that situation currently. I have a video card that is DVI only (no HDMI output). My HDMI TV only has the 15pin RGB input, so I have to convert from DVI to RGB, thus voiding the DVI all together. Luckily I have a new 570GTX on the way and will be using the mini HDMI from PC to TV. Maybe your TV has the DVI input. Mine (and many others) do not. Good luck!
(oh, yeah, my video games still look great on my TV even with the RGB cable. As good as these HDMI televisions are, high end PC monitors are better and offer much higher resolutions that are capitalized on by high end video cards. But I prefer the bigger screen!)
