Review: Very Nice Unit but is incompatible with Rokid AR Glasses - I bought this unit to be able to switch output from a Roku Stick and a PS4 to a television set and a set of Rokid Max AR glasses. The output works perfectly on the television set, however for some reason, the glasses are not working with whatever signal this unit is putting out. The glasses work correctly if the output from either the Roku Stick or the PS4 are connected directly to the glasses, but not the output of this unit. I have tried switching the cables around in all possible configurations to make sure that the cables and unit connections all work correctly, which they do. It's unfortunate because this seems to be a high quality piece of equipment. The case is metal with high quality markings, the LED's are nice and bright, and the remote functions perfectly. I have tried to contact tech support, but so far, have been unsuccessful. I gave the unit three stars because I feel that is a neutral score. If the issue can be resolved, I will gladly give the unit five stars. UPDATE: The seller saw my review and reached out to me to discuss my issues with their product. After some investigation, they determined that their unit is not compatible with the Rokid Max AR glasses that I was trying to use it with. As a result, the asked me to return the unit and they will give me a full refund. They even sent a shipping label so that I would not have to pay the return shipping. I am increasing my review to five stars because it is a nice, well made unit with a lot of features, and it worked flawlessly with my TV set, just not with the glasses.
Review: It just works - Worked well with my fairly complicated setup using a mixture of new AV equipment and some ancient stuff: Apple TV 4K 2nd generation, Epson QB1000, and Integra DTR 9.9 for sound. I'm able to view 4K HDR10+ from the Apple TV, and 4K HDR10 from a Nintendo Switch 2. Also using an OREI 4K extender to get 4K HDR10+ video over Cat5e. Audio extraction over Optical to the Integra provides 5.1. Everything controllable via HDMI CEC with the Apple Siri remote. Impressive...

## Questions & Answers

**Q: I want to connect a roku ultra to one input and supply that signal to a 4k tv and an older denon avr. will this switch still pass the 4k to the tv?**
A: Yes, it will. I have two inputs; one being an Apple TV and the other being a cable box. I also have two outputs, which are a 4K 65” TV and a Samsung sound bar/subwoofer. This works fantastically. 4K output on the TV.

**Q: Can i use a 100ft fiber optic hdmi cable on one of the outputs with no issues?**
A: I believe you can use 100 foot cord you may get some lag i use a 50 foot HDMI cord with my orei 2x2 Matrix switcher box and have no problems

**Q: The computers plugged in to the device only see the matrix as a 1080p capable device.  How do you get windows to see it as a 4k device?**
A: Connect your 4K tv to the output 1 and set the EDID dip switches on the matrix to 1100.

**Q: Can this output 1080p@120hz? Description mentions 4k and 2k @ 60HZ but what about 1080p?**
A: No, it doesn't support 1080@120hz output.

### ⭐⭐⭐⭐ This is almost the perfect HDMI Matrix Switch. See the review for why I took 1 star away from it.
*by T***R on October 27, 2024*

I have used OREI Splitters and Matrix Switches for awhile. They just work great and can handle 4K 60Hz. Alot of splitters and matrix switches on the market can only handle 4k at 30Hz. I've never had a problem with picture quality, splitting HDMI signals to multiple monitors or using a Matrix Switch to control what HDMI input gets director to which Monitor I choose. There is one caveat to this. It's the Power Connector that OREI boasts about. They speak about how the power connector screws into the back of their splitters and matrix switches. I really like that idea so it does not accidently get pulled out, however, the quality of this power connector is Awful. The wire used and connection to the connector is terrible. You move it slightly and it will disconnect. It's not the connector, its the wire cable and how it is attached to the power connector. If you read this OREI, please redesign this and solve the one single issue with these devices. Would I recommend, you bet. Just know going in, that this an issue but as long as your not moving the device around often, then you should be fine. Hope this helps. Still love the product(s) performance!!!
