VESA approves DisplayPort 1.1: kiss those DVI and VGA ports goodbye


Get ready for hot, hot convergence kids 'cause the DisplayPort 1.1 specification was just approved. The new VESA-approved digital interface standard is meant to replace DVI and VGA ports while co-existing with HDMI for HDTV connectivity. As you can see in the picture above, it's about the size of a USB connector yet offers 2x the performance of DVI in a much smaller package. They also bake in a nasty dollop of HDCP 1.3 content protection to keep the Blu-ray and HD DVD kiddies happy. The wee size allows the interface to be included in smaller handheld electronics while enabling direct-drive LCD panels thereby eliminating the need for non-panel LVDS electronics in the monitor designs. Of course it also supports pass-through of DVI and HDMI signals via simple adapters similar to DVI-to-HDMI variety on the market today. So which of our esteemed manufactures will bite first? We're not sure, but VESA isn't shy about using Dell's high-end XPS systems in their marketing collateral. Of course, the question they don't answer is, why not just move everything to HDMI? For that, you just have to look at who backs royalty-free DisplayPort (the PC industry) and who backs HDMI (the consumer electronics industry). Yeah, we know.

DisplayPort to support HDCP, too

Analogix Semiconductor just announced its first receiver chip for the DisplayPort interconnect. Yeah, DisplayPort, the latest video interconnect standard which looks to replace HDMI, DVI, and even analog VGA connectors currently found in monitors, TVs, laptops and other portable consumer electronics. What's more, it's fully supported and even, preferred by the Video Electronics Standard Association (VESA) as a low power, low pin count, license-free video interconnect standard. The ANX9811 chip is now available to manufactures for sampling and, when paired with the company's existing ANX9801 transmitter, supports a full 10.8 Gbits/second data rate and WQXGA (2560×1600) resolution over a 15-meter cable. Fine. But the real news here is that the chips will support the DisplayPort 1.1 spec which was proposed in November and should be finalized by VESA in early 2007. The modified spec brings support for DisplayPorts own copy protection technology and now, finally, HDCP. It's not that we're big fans of HDCP or anything, but if we have to be saddled with wire-line encryption, let's choose one and be done with it, eh? Expect to hear more about DisplayPort at CES where Dell, HP, Lenovo, and Samsung will be laying out the interconnect's roadmap in an fractured industry love-fest. Still, like any good standard, you'll have choices: Intel's also pushing their UDI (Unified Display Interface) interconnect to replace both DVI and HDMI in PCs. If we're lucky, Adam Smith will grab whole lot by the throat to shake out a unified standard before the decade is up.

Vogel's new LCD stand

LCDs are so small and light they can be placed anywhere. You can put them on mantels, on nightstands, or on the wall. But what if you want the TV on the wall but are having committement issues on where? Vogel has a new mounting system that might just work for you. This really isn't inovative but rather just practical. This is basicly a stick for LCDs to mount on, but you know what? It works. The mount will support up to a 24-inch VESA complient LCD panel and is available for $479.

DisplayPort: Because what we really needed was another connector

Ok fess up, who requested another digital interface for video and audio content? Since UDI, HDMI & DVI weren't complicated enough, VESA has come out with their own digital connector to replace VGA, DisplayPort. They originally announced it a year ago, but it is now ready to go, the only question is does anyone care?

This article from Digitimes breaks down the challenges DisplayPort faces and what (few) benefits it offers. Unlike DVI/HDMI/UDI, it isn't backwards compatible with anything. If you replace your PC, DVD player TV or monitor with a DisplayPort device you'll have to replace anything connected to it. It also has it's own content protection scheme, much like HDCP, but once again not compatible.

We don't really see this standard taking off with no backwards compatibility (however this release from Dell/HP/Lenovo indicates it is "possible" to have legacy compatibility with DVI 1.0) and both high definition DVD formats using a different copy protection format. With its only apparent advantage being a lack of licensing fees, is there a space for DisplayPort?
