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!"
I do however see uneven brightness on LCDs (and I've also read about it). This happens because LCDs do not produce "true black levels" as the other competeing technologies do. The backlight prevents a black scene from ever being true black, so this will never be acheived on an LCD TV. What some LCDs do to get darker scenes dark, they use a cheating mechanism by dimming the backlight during dark scenes. When the scene moves from dark to light, the light amplfies back to its normal level, which in turn gives the display what I call a "breathing effect". Unfortunately, this technique is not a successful approach as it is easly noticable. Another reason why I will never go LCD, unless they can offer something that I cannot get from a DLP HDTV.
