Dell, HP, Lenovo Announce New Display Protocol 188
An anonymous reader writes "If HDMI, DVI and UDI weren't enough for you, several major PC manufacturers have announced a joint alliance to come up with another display adapter, creatively named Displayport. The new method is backwards compatible with DVI, but offers double the bandwidth."

Last I heard, it was flopping horribly. Wonder what happened.

Probably. It may be necessary to have it for certain "protected" media in Windows Vista, but the easy solution is to not buy that protected media. And not buy Vista as well, assuming it comes out.

Keep in mind that today's top-of-the-line LCD displays, running at QUXGA (3200x2400) require multiple DVI dual link connections, and comprise multiple discrete panels, each with its individual signal feed. A display by IBM (T221, I believe is the model number) currently does this.
I believe Lenovo manufactures IBM's flat panel displays. Could the T221 be a potential justification for Lenovo to co-sponsor this technology?

No, the entire industry as well as the Digital Display Working Group [wikipedia.org], of which Apple is not a part, calls it (their design) Dual-link DVI. It is used any monitor with a resolution above 1920x1200 and I think it's been available on nVidia and ATI cards for a few generations.
No, Apple does not invent as much stuff as you'd like to think.

IBM's manufacturing partner for the T22x family was IDTech in Japan.
IBM stopped selling the monitors almost a year ago, probably right about the time they sold their PC division to Lenovo.
Furthermore, DisplayPort has only a negligble bandwidth lead over DVI. The total raw capacity of DisplayPort is 10.8 Gbps versus 9.9 Gbps for a dual-link DVI connection (or a "type B" HDMI connection).
The main reason for DisplayPort's existence is the onerous licensing terms for HDMI - and some technical requirements that make it harder to miniaturize and integrate the DVI/HDMI electronics.

Actually, no. Even 1600x1200 is just beyond the original bandwidth limit.
Instead you see the abomination of people sitting in front of 2 smaller monitors.
Bah, I prefer having 3 monitors at 1600x1200... The abomination is not having a choice.

Here's a spec comparison (includes bandwidth) of DisplayPort, LVDS, DVI, and HDMI (I believe it's from VESA):
