Intel's update to Wireless Display 2.0 allows streaming of protected content to HDTVs

It didn't make a big deal of it in the same way it did with, say, its new 3D transistors, but Intel has quietly updated its Wireless Display 2.0 technology, which allows you to stream content from a compatible laptop to HDTVs with a special adapter (such as Belkin and Netgear offer) attached.

It didn't make a big deal of it in the same way it did with, say, its new 3D transistors, but Intel has quietly updated its Wireless Display 2.0 technology, which allows you to stream content from a compatible laptop to HDTVs with a special adapter (such as Belkin and Netgear offer) attached.

The big deal about the update is one of those "well, duh" improvements that you'd think would have come with launch: WiDi 2.0 now supports streaming of protected content from DVDs and Blu-ray discs. It will also let you encode video up to 1080p resolution as well as adding surround sound support.

Not bad for a free update. However, you will need the latest hardware in order to get these new features working -- which includes a 2011 Generation 2 TV adapter and a laptop with a Sandy Bridge processor -- along with the newest Intel HD drivers. Otherwise, you're stuck watching DRM-secured movies the old-fashioned way -- sticking a disc in a player already hooked up to your HDTV.
