Displayport goes internal

IDF Spring 2008 Driving panels everywhere

INTEL'S NEXT GENERATION laptop platform, code named Montevina, has a nice feature that remains quite unheraleded, Displayport (DP). Not only does it allow you to drive an external DP monitor, it uses it internally.

Intel had two panels from different vendors up and running at IDF, a good sign because Montevina notebooks are right around the corner. It won't buy you much on the inside, possibly saving a bit of engineering, but it should allow you to push some pretty nice displays with your new lappy.

One other nicety of DP is that the connector is much smaller than a VGA adapter, and minuscule compared to DVI. Coupled with the fact that it isn't burdened with the same crushing license fees as HDMI, you have a very attractive port for notebooks large and small. You cold even realistically envision notebooks, even small ones, sporting multiple monitor outs.

On the down side, and it is a very down side, DP is DRM infected. The only good thing since flat panels in the monitor world has a rights removing dark side. Even with this baked in malware, DP is a good thing, a really good thing. The sooner it takes over, the better. µ

DisplayPort DRM etc

Found this very enlightening article

http://www.edn.com/article/CA6402885.html

giving an overview of HDMI, DisplayPort, UDI etc. It says that DisplayPort originally supported "Certicom" copy protection, but it looks like nobody is going to use that, so they added the same HDCP that infests HDMI.

Ed Felten did a study of HDCP a couple years ago

where he found that it seemed deliberately designed to be easy to crack.

just dont buy it

The content protection only starts working with DRM infested content - so just refrain from buying that crap. After all, who was it who invented the slogan "Piracy - the better choice (TM)"?^^ Of course, you could also just live without it...

Read those linked articles

Lawrence, thanks for those interesting article links.

The edn.com URL is busted, but their Asia site has it at http://www.ednasia.com/print.asp?articleId=10569 (or article.asp if you prefer your online magazines with utterly horrible side-sliding text-obscuring ads). Weird presentation format, you would think they'd have heard of embedded images and hot links by now...
