forgot to mention, Displayport allows you to put the display much further away than VGA/DVI with no signal loss. Good for Kiosk systems and situations where you don't want (or can't have) the machine physically close to the screen you want to display.
"Like DVI however, DisplayPort does not support audio content. VESA however, would not see this as a problem since it didn't hinder DVI's performance in the market. On Monday, the group behind HDMI announced that more than 50 Desktops, Notebooks, Motherboards and Graphics cards are shipping with the HDMI technology on-board, sending a message to VESA that it plans to fight to become the standard.
DisplayPort has many advantages over HDMI however and is very powerful. It performs with relatively low power-consumption, has a low pin count and can transmit data at 10.8 Gigabits/second, supporting resolutions up to 2560x1600 (WQXGA) and possibly beyond. It can perform properly over a length of cable up to 15 meters in length, which many see as a great advantage over HDMI."
"The Video signal is not compatible with DVI or HDMI, but the specification will allow pass-through of these signals. DisplayPort supports embedded clock, unlike DVI/HDMI which require a separate clock pair. The data transmission protocol in DisplayPort is Micro-Packet based which is extensible in future to add features, whereas DVI/HDMI transmission protocol is Serial Data Stream at 10x pixel clock rate. However one of the biggest advantage that DisplayPort provides over DVI/HDMI is that DisplayPort is intended to consolidate both external(box-to-box) and internal (LCD panel) display connections."

What's the point of DisplayPort?
I already read about it, but I'll ask anyway =D

It's the future. Standard DVI plug is too big. Mini DVI hasn't really taken off (despite the macbook.) Displayport cable can carry Audio too.

not to mention DisplayPort is loyalty free, much like the VGA port we've been using for decades
UKNigel @ Mar 20th 2008 11:02AM
Ah good, there's no loyalty involved. Huh?
nonamo @ Mar 20th 2008 2:35PM
phew, gotta hate those loyalty cards
:P

DVI doesn't really seem that big to me...
And why not standardize video cords and use HDMI? Some licensing shit?

Also, besides those technical details, yes, it's a licensing issue.
