OREI 4K 4x4 HDMI Extender Matrix - UltraHD 4K @ 60Hz 4:4:4 Over Single CAT5e/6/7 Cable with HDR Switcher & IR Control, RS-232 - Up to 230 Ft - 1080P Downscale - 4 x Loop Out - 4 Receivers Included

Purchased for a sort of media cabinet i'm building that has two Raspberry Pi 4's, a mini Windows 11 computer, and an extra input/output for a 3rd Raspberry Pi 4 to plug in as a test. I'm also using the Orei HDA-912 audio extractor (two of them), plugged into the loop out hdmi on two of the outputs. I need the same content extracted from a playback but at different volumes, so using two of those audio extractors make that possible. No interruptions on an output if I select another output to that same source. I did have to perform a factory reset...I couldn't log into the web interface, but was able to get to the login screen. Only way to reset it to default is via an RS232 command, which it came with the cable to connect to the rear of the unit and has a 9 pin female plug that will plug into a computer serial port, but I had no working computer that possessed such port, so had to acquire a USB to serial cable at a local retail store. I ended up adding that RS232 to USB cable to my installation, as I found a way to remotely control it (and thus automate it as well) by having the mini Windows 11 PC send commands to the Matrix using a simple batch file (power on/off, select inputs/outputs, or recall a preset). Only power supply needed is the one that connects to the Matrix, it is able to power up to 4 receivers via the CAT cable.

Plug and play, gotta love technology. The only thing I will say is I have cat5e cable and 1080 signals come thru fine, when switched to 4k input, I get white blocks all over the screen. And sometimes I do get white dots flickering on the screen even in 1080p but only on my newer Sony 75” tv for some reason, it’s only noticeable in dark images, and I attribute that to the wiring not being cat6 or higher, I plan to change the wall outlets the receiver is plugged into, as sometimes I replug the cords into the outlet and the dots go away, but again only my 75”, other TVs 55 and below no issue at all. IR sensor placement is crucial, inches make a difference. Am able to feed Comcast box and security nvr to all my TVs now. Programmed all remotes of different inputs devices into logitech hub based remotes at each receiver station with the Matrix transmitter ir taped to the ir repeater of the logitech Harmony remote. Works perfectly.

Right about a year old and just starting to have issues. Randomly picture will go pink (all on tvs). Need to cycle power on the main unit and it will correct it self. Also lose connection to some tvs at times. Need to cycle power at the mini box on the TV to correct.

We ordered the OREI 4X4 Extender Matrix to replace a projector system in our church. The Extender is very easy to install and operate. We initially experienced problems getting a signal over 65 feet from the extender to our new LED monitors, and our configuration required a minimum of 135 feet. We had hoped to use the existing CAT-7 Ethernet shielded cabling we had in place for the projectors. It was shielded but was the FLAT white style. The OREI technical support team suggested that we use ROUND shielded CAT-6 cable. We purchased 150 ft. of the round cable to test the recommendation, and it worked great. We have now replaced all our existing cabling with the round shielded cable and the video system completely meets our expectations. Based on our experience, I highly recommend that all users of the OREI UHD48-EX320-K Extender Matrix use only ROUND shielded Ethernet cable.

This is great and works beautifully the biggest issue is remembering button in to HDMI out light configuration when you change things. Other than that they work beautifully.

It didn't work with directv on non high definition, no sound and poor picture. The signal that comes out of a dome antenna.

This unit surprised me. It relplaced two hdmi 4 port extenders and is 4K. Out of the box it defaulted to 1080p, but after figuring out how the web interface works, its now almost perfect. Its lacking wifi and ARC support, but for the price its a great value and offers more options than what i had previously.

doesnt work out of the box. Red standby LED alle the time the matrix wont turn on, no response from remote or front buttons. The support wnsers quick with nwe ugestions but nothing helps and I havent been able to use the product still two weeks after I recived it

Exactly what I needed to complete my set-up. Item arrived in good time and as described

Very happy with this matrix. I needed it my motorhome to distribute signals to the 3 tv's. Had to have it professionally installed as I wasn't comfortable with doing it myself. It works perfect. Highly recommend

Works seamlessly with app. EDID settings set to work with all screens

It worked as expected just out of the box and is extremely easy to use.

I am very happy with this matrix. I needed it in the mosque to distribute signals to the 3 TVs. Installation was comfortable, and I did it myself. It works perfectly. Highly recommend
