OREI4K HDMI Over Ethernet – HDMI Extender with HDBaseT Technology, Resolutions upto 4K@60Hz, Bi-directional IR & Power over Ethernet, RS-232 control, Audio Extractor & HDMI Over Cat6 up to 115 Feet

At first, I thought this product to be a bust like the others I have tested. I needed an HDMI over CAT solution that would provide audio extraction, and in the end this device delivered all around! I was prepared to write a bad review and make a return until I discovered that there was a bad HDMI cable in the chain that was allowing the 4K projector and my laptop to negotiate a signal that was too fast for it to transmit.Luckily, I thought to test with new cables, and have been very pleased to have a reliable signal again, with flawless delivery of any video signal (4K 60fps tested) and it's audio.This was a two-for-one solution as I had tested two audio extractors which both failed, and this device eliminates the need for seperate audio extraction. Thank you OREI!

After trying 2 different brands without success, I had these recommended to me. I picked up 2 sets, and they worked perfectly out of the box! We will just have to see how they last.

Excelent, easy install and run on minutes, 100% recomended,I used it to connect a laptop to an 80" TV and to a video projector simultaneously (requires a split) and it worked perfectly, good resolution, no problems and easy installation, the POE works perfectly.

Worked great

This unit does not pass 4k signal from the loop back which makes it completely useless
