It's so easy to forget that the RT can do far more than a typical iOS or Android tablet. Here's my RT running 8.1 driving my 60" TV as a 2nd display (attached via an HDMI cable) in full 1080P resolution. I'm able to stream a live video on the TV while streaming another video on the RT's screen. Sean Ong showcased that in his epic video "Why I love my Surface RT" but I wanted to drop in a quick photo.
