A big problem with most portable TV's is that they go to "blue screen" when there is too much static in the video. I found a TV that is very tolerant to static in video, and it will go to "black" only when the video is almost completely gone. It's funny, really...I saw another store selling a TV, with a note saying that it doesn't go to blue screen...while they had a video on their page clearly showing it going to "black" when there was some static in the video. It doesn't matter if it's blue or black, if the picture goes away it's a bad thing!
This video actually shows something else: 5.8GHz does not go through objects very well. This was a simple 25mW 5.8GHz transmitter, using the receiver built in to some FatShark goggles and fed to the TV. When the video goes away, I ask my assistant to turn around, and instantly the picture comes back, and it is very clear. Just his body was blocking the signal almost totally at that distance. That's one negative with 5.8Ghz and something users need to be aware of.
