OREI 4K HDMI Extender Balun UltraHD 4K@60Hz 4:4:4 Over Single CAT6/7 Cable with HDR & IR Control-Ethernet Cable Up to 165 ft-Power Over Cable

Amazing. These are great at 4K 60-120hrz. If one stops transmitting. And resetting each (by button) doesn't work. Unplug the transmitter and receiver for 1 min then plug back in. Installed 16 on TV is one bar going from 55' to 135'. Clear picture so far no failures. Installed Superbowm Sunday 2025. Any issues I will update post.

I used these to connect an HDMI signal from a DVD player to a Yamaha receiver that's in a media closet far from the DVD player. I ran the signal over Cat 5e ethernet and the baluns worked good with no signal decay.

I was honestly disappointed when I first set up these adapters to extended my Chromecast content to another room. I was getting all magenta colors on the remote location when the display is set at 1080p 60Hz. But when I switched to a lower refresh rate like 4K 30Hz, video was good. Then I tried extending my Fire TV cube content to a different location with a smaller 1080p TV and that worked perfectly at 60 Hz.So I was pleased with the end result and continue to use this to transmit 1080p content since this isn't capable transmitting 4K reliably even though it's advertised as such. Fortunately, I'm buying a higher spec version of this for my 4K transmission and it should perform better than this one.In conclusion, your mileage may vary but some of my devices can't be viewed at 60 Hz at the remote end. Still a nice and simple product.

Works great! We have a remote media room, over 60’ from the TV location, and this HDMI extender solved our connection issue perfectly..

Works great. Would purchase again if I needed one.

My theater setup includes a Dish Network Hopper 3 with UHD 4K (HDMI 2.0), an Amazon UHD Firestick, A Sony UHD 4K Receiver #STRDH590 (HDMI2.0) , and a Panasonic DVD player (HDMI 1.2). This product would only work with only the Dish Hopper 3 and the Amazon Firestick. The product is not compatible with my other mainstream HDMI 2.0 products, thus I provided a negative review based upon poor compatibility with mainstream A/V products. On the positive side, this product runs very cool compared to other previous HDMI Baluns which suggests the potential for longevity.

After getting frustrated with garbage HDMI cables, and even having no success with fiber optic HDMI cables I settled on this. I needed a run of about 40-50ft and this worked perfectly. So much so that after several months I bought a second one for another project. I know good fiber-optic cables exist and can be a cheaper solution, but I kept having bad luck. HDMI over "ethernet" is very reliable if you don't mind the converter boxes sitting around.

I just needed something to get my new 4K monitor up and going. My old 1080p was fine, but need the boost to get the 4k. This worked perfect for my 15 foot run. I noticed it was remoted powered and even extended IR if needed. Nice unit.
