Nothing there as to support. If I were to guess it's some HDCP issue or other signal interference. About all we see is to chance the wireless HDMI or the set.
Again, I have NEVER found any fix except to start changing parts of the system. This includes HDMI cables and try other HDMI ports. But my bet is you did that.
I recently bought my first Samsung TV (UN32EH5300). I transmit the HDMI signal from the satellite receiver to another room using an IOGEAR video transmitter/receiver (GW3DHDKIT). It works perfectly at 1080i with my other TVs (Toshiba) but the Samsung keeps dropping the signal every few minutes, sometimes spontaneously, often when I use the TV remote. It makes no difference where I place the video rcvr or how close it is to the transmitter. After a minute or so, the TV usually reestablishes the connection but it obviously makes it impractical to view remotely with this TV.
I see a number of posts with somewhat similar problems of dropping video but, so far, have seen no solutions
