Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
BUT it requires LOTS AND LOTS of bandwidth/speed/power and memory to run at that resuloution. So many games will stay with 720p so they can still have other features like AI, collisions, physics and other fun game things.
