NAMCIM Wireless HDMI Transmitter and Receiver, Plug & Play, No Delay, Ultra HD Wireless HDMI Converter Dongle Adapter, Streaming Video/Audio from Laptop, PC, Smartphone to HDTV Projector

No cables! Easy plug and play. Great if you want a portable device or if you want to set up another screen and not have to run wires. Works just as well as having a cable plugged in. From what Ive tried, no issue with audio or video synchronization.

Comes with every cable and plug needed, which was very nice. But, no matter what I tried, I could not eliminate the jitter. My configuration involved Apple TV (50Hz and 60Hz at 1080), a soundbar, and a projector. Distances were about 20 feet. 1. I tried going direct from Apple TV to the transmitter. 50Hz gave the least jitter, but it was still there. 2. I tried Apple TV to soundbar and soundbar (HDMI out) to transmitter. Jitter, same as above. 3. I tried Apple TV to an HDMI splitter, and one output to the projector and the second to the soundbar (using the transmitter to receive audio). This actually worked flawlessly while watching a movie one night. However, the next day it didnt work because the transmitter seemed to steal both the video and the audio in the splitter, so the projector never had a signal; I couldnt figure it out and tried everything for about an hour! I wanted the Apple TV and soundbar together because I have better performance when the Apple TV is plugged into my LAN rather than using WiFi. But the jerky picture using the transmitter was a deal breaker for me. I have TWO different transmitters, and they both have the exact same issues with jitter, especially at 60 Hz.
