VGA. DVI. HDMI. And now DisplayPort. I’ve mentioned it before, and now it seems that it’s gaining momentum.

The real question is: how is it different or better than HDMI, which seems to target the same purpose? Audioholics has an answer for you:

HDMI is a great consumer electronics interface, but VESA does not feel it is the best solution for PCs as a monitor interface. A somewhat limited performance is available in terms of resolution and color depth for PC monitors (see comparison chart for exactly how this might impact future displays). HDMI is designed to be a premium A/V interface, rather than as a broadly available general purpose display interface. The HDMI specification is not geared to unifying internal and external display connections; its primary focus is consumer electronics.

The also have a great table comparing DisplayPort, LVDS (???), DVI, and HDMI.
