Trying to connect PC to HDTV over 1080P. It worked for a while - about a week, then the transmitter began to repeat connecting and disconnecting to the PC. The PC kept trying to adjust the display when the channel was disconnected and reconnected - almost every minute and this rendered both the PC and the TV unusable. Tried source and display (laptop and monitor) and same problem. When I lowered the signal level (from 1080p to 720p) it worked for a while (about an hour) without any problems, then the problem reappeared with a 720p signal. A big disappointment for the price. Unfortunately I installed the product a few weeks after receiving it from AMAZON and the free returns window closed when the problem started. AMAZON just told me to contact the manufacturer directly and I emailed the manufacturer. Hope they accept the return.
