Dell, HP, Lenovo Announce New Display Protocol

Posted by ryuzaki0 on from the forward-progress dept.

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."

    From TFA:
    The DisplayPort specification also addresses the industry need for a ubiquitous digital interface standard with a compact connector, as well as optional content protection, that can be deployed widely at low cost. A protected digital interface that can be easily deployed on a PC enables broad access to premium content sources such as high-definition movies.

    The only bright light in this spec. That and it supposedly can support *really* high resolutions.

  3. Bandwidth... by setirw · · Score: 5, Informative

    I've noticed that a lot of users are stating that extra bandwidth is unnecessary.

    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?

      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.

    We Mac users call it Dual Link DVI

    No, the entire industry as well as the Digital Display Working Group, 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.
