Wireless HDMI for Everyone
Sadly a better solution already exists: my 2012 Panasonic TV connects wirelessly to my network, and my laptop can stream videos to it without having to install <i>anything</i>, all via DLNA:<p><a href="http://en.wikipedia.org/wiki/Digital_Living_Network_Alliance" rel="nofollow">http://en.wikipedia.org/wiki/Digital_Living_Network_Alliance</a><p>Here's Panasonic's page outlining such features in their TVs:<p><a href="http://www.panasonic.co.uk/html/en_GB/Products/VIERA+TV/VIERA+Overview/Smart+Internet+TV/8935620/index.html" rel="nofollow">http://www.panasonic.co.uk/html/en_GB/Products/VIERA+TV/VIER...</a><p>It's a lovely idea for retrofitting to older TVs, and sharing between laptops is really neat. For anyone who's bought a TV in the last couple of years, though, the device is redundant.<p>(it's also apparently very easy to share content from smartphones, tablets and so on, but I haven't had the need (or a chance) to independently play with this)
