## Description

desertcart.com: OREI 4K HDMI over Ethernet Extender Balun - HDBaseT UltraHD 4K @ 60Hz 4:4:4 CAT5e/6/7 Cable with HDR, CEC & IR Control, RS-232 Up to 400 Ft Loop Out POC Audio Out (UHD-EXB400R-K) : Electronics

Review: Solid choice for this type of gadget - I needed to throw an HDMI signal (standard 1080p 60Hz) across the house. I also wanted to be able to monitor the image locally at the source, so that I wouldn't have to walk across the house to check on the image and sound. Enter this set of gadgets. I've used Orei products before (their HDMI splitters are REALLY nice and rock-solid) so I chose this product with some confidence. I was not disappointed. These worked exactly as described, throwing the signal cleanly to the destination. The local HDMI loop out worked just fine. The RF Blaster transmitter and receiver units worked very well too, which made remote control of the source very simple. In all, everything worked precisely as it should and held up solidly for a session that lasted MANY hours (probably about 5 or 6 hours of continuous operation). These Orei boxes barely got warm. I couldn't be more pleased with the performance of this product, and the price is mind-boggling cheap. Notes: Cat-5e and Cat-6 cables are slightly different internally. You will get longer range from a Cat-6 cable than a Cat-5e cable. Unless you're using existing Cat-5e for whatever reason, I'd recommend procuring a well-made Cat-6 cable to go with this Orei product. You'll get the maximum transmission range with Cat-6 cable. According to the manual that came with this product, Cat-5e range for 1080p 60Hz signal is 197ft maximum and Cat-6 range for 1080p 60 Hz signal is 230ft. The ranges for a 4K 30Hz signal are 115ft for Cat-5e and 131ft for Cat-6. An odd quirk: the local HDMI loop out didn't work for me until I plugged in the receiver at the other end of the Cat-6 cable I used. It seems you HAVE to connect the transmitter and receiver together in order to see anything on the HDMI loop out. Not a problem at all, but kind of odd. Just needs to be kept in mind when setting up. Finally, this product is powered from the transmitter end only. You do not need to power the receiver (in fact the receiver doesn't even have a power port). This is nice - some products of this type require power on both ends but this one does not. Makes for simpler installation/deployment.
Review: Works Perfectly - It's not the cheapest HDMI extender but it's probably the nicest. Its actually four products rolled into one. The HDMI extender. A HDMI splitter. An infrared remote extender. And a HDMI audio breakout. You need most of these to hook two TVs to the same cable box and the fact that they are integrated saves a lot of wiring and clutter. Combining the HDMI extender and the infrared remote extender means you only have to string one wire between the TVs instead of two. The advantage of going to CAT 6 instead of HDMI is that CAT 6 is cheaper, it can carry the signal further and you can install the connectors your self. You can't install HDMI connectors on cables so to extend with HDMI you have to buy a HDMI cable that is the correct length and you have to drill holes through walls that are big enough for the HDMI connectors. So you would need 0.75" holes for HDMI vs 0.2" holes for CAT 6. I actually used some unshielded CAT 5E because I had some lying around. (CAT 5 is not recommended because its lower bandwidth compared to CAT 6 or CAT 7 which are recommended.) My run was 80 feet and it works just fine at 720p resolution. However, it might not work at higher resolution and if I were doing over again I would go out and buy some CAT 6. Stringing cable is a lot of work so its better to do it right the firsts time.

## Questions & Answers

**Q: Does the splitter (1 hdmi in 4 hdmi out) need to be powered, or does it also get poc from transmitter or receiver?**
A: All of our HDBaseT extenders support power over cable so you can power the transmitter and the receiver will get power when you can connect them to the transmitter using a cat cable.

**Q: I want to use this product with my playstation 5 and sony tv.
is 4k60, hdr-10 and hdmi-cec available on this product?**
A: Yes, it will work for your intended use.

**Q: I set up the units and appears to work fine.  earc is also working - used only for netflix from oled to receiver. the units get warm?  is that normal?**
A: Yes, it's normal for the unit to get a bit warm during use.

**Q: Does it have to be a direct ethernet cable connection between both the tx and rx or can the tx be connected to a poe on my network switch?**
A: This requires a direct connection between TX and RX wihout a network switch in between. The following model UHD-EXC400-K will work but it doesn't support POE so both TX and RX include their own power adapter:

### ⭐⭐⭐⭐⭐ Cheaper and better
*by J***E on August 26, 2025*

Replaced an Altoona balun that had been in service for five years with this unit. Hooked it up and it worked as advertised without any fuss and one less power connection. The unit I replaced claimed 4k, but the OREI produced a better picture with the same connections. I have not tried the IR remote functions because my Universal remote is still working, but I now have options if that system fails. This unit was half the price of the one I replaced with more functions and better picture resolution. The box size is approximately the same as the old unit.
