I have have a question for the GA-series owners out there. On the Amazon listing for the set here Amazon.com: LG Electronics 55GA7900 55-Inch Cinema Screen Cinema 3D 1080p 240Hz LED-LCD HDTV with Google TV and Four Pairs of 3D Glasses: Electronics Under "Key Features" it lists Miracast support. Under "Additional Features" it lists NFC support and WiDi support. Do these features actually exist? I know these features are NOT supported in the core Google TV OS, but has LG created these outside features themselves?
