OREI 4x4 HDMI 4K Matrix Switch/Splitter, (4-Input, 4-Output) with Remote Control Supports UltraHD 4K@60Hz 4:4:4, HDR, YUV, HDMI 2.0, HDCP 2.2, 3D, 1080p, 18 GBPS - Downscaler (4K & 1080p Together)

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.

Works great,as advertised!!

I have a pretty niche use case for this, but I was pleasantly surprised to find a product that did what I was looking for, and at such a reasonable price point. I have an AppleTV and a Roku that I want to flip back and for between two different TVs in various combinations. On one of the TVs I need to extract the audio to run it into a receiver, which this unit also lets me do. I had no idea a product like this existed, and it is almost perfect for my need. Reasons not 5 stars: - The remote is important for my use. It works, but it is flimsy and the buttons don't always respond well. - Not sure if it is an Orei issue or the nature of the technology, but sometimes I want one TV off. But no matter how I set it, it seems some sort of signal "leaks" through the switch that causes the TV to turn itself on. A minor issue, but annoying. But definitely would recommend.

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...

This HDMI matrix switch is a great solution if you need to route multiple HDMI sources to several displays. With four inputs and four outputs, it allows you to send any connected source to any display, which makes it very flexible for different setups. The switch supports 4K at 60Hz with 4:4:4 chroma, and the picture quality remained clear and stable during use. The downscaling feature is also useful because it allows 4K and 1080p displays to be used together without compatibility issues. The included remote control makes switching sources quick and convenient. Once everything is connected, it works reliably and makes managing multiple HDMI devices much easier. Overall, this is a solid HDMI matrix if you need a flexible way to route multiple video sources to several displays.

This product works exactly as advertised. I have it currently set up with a PlayStation 5, Nintendo switch, Roku stick and Nintendo Wii as my inputs. My four outputs are two Dell 32-in monitors, 65-in Samsung TV and a 100-in projector. It is very easy to select between which output and input you want to set up. The remote works very well also. I like the fact that the unit comes with two tab ears so it can be mounted on the wall or mounted on a flat surface. I also like that there are manual buttons to switch between the inputs for each output. The only thing I do wish is that when mounted on a wall there's a way to be able to see the lights so you know which output has input showing.

I have been generally pleased with this device and control it remotely over a network. Before I ordered it, I inquired about video delays and was told that there were not any. Apparently the answer applied to the time difference between input and output. What I found is that when you change an input, the related output goes black for approximately 4 seconds before the new input appears. While this is not a problem for setting pre-show configurations, it is a distraction for switching inputs during a performance. I will continue to use it for basic video routing, but will need to use a HDMI switcher to select and change sources for displays during a performance. I submitted a ticket on the OREI website several days ago asking if this behavior was normal. Unfortunately, I have not received any response.

This is a nice little unit. However if you want to use it with Verizon Fios One and have 4K and 1080p tv/monitors -on/hooked up at the same time, the Verizon Fios One box will default to the lowest resolution of what is hooked up. If you only have 4K hooked up, Verizon will broadcast in 4K, and the matrix switch will deliver a 4K picture to all 4K tv/monitors. I spoke with Verizon Technical support and they will not allow you to over ride the Fios One box and have it set to constant 4K output. The downscaler function on this unit is useless with Verizon Fios One. You can not have mixed tv definitions delivered. If the manufacturer of the matrix device would dedicate one hdmi input to 4K and one output to 4K and have that input relay back to the source everything is in 4K, the Fios One Box would stay in 4K mode. Then the device would have to stop all two way communication on the other 3 hdmi outputs to mixed resolution monitors. The downscaler would then be applicable. Verizon Fios One is very limited as to what third party devices can be used with TV or internet. We can no longer use our more powerful wifi router because it would disable features of the new Verizon system.
