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.

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...

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!!!

The concept seemed straightforward. The manual was a bit intimidating. In fact, it was almost plug and play. We had 2 inputs to start with and 4 outputs. 2 were on HDMI Cat 5 extenders, one was just HDMI and one output was a wireless HDMI extender. We also used the audio splitter for our main input channel and linked it to the mixer for our church. All worked beautifully. Hint: for video routing, follow the simple but important instruction—push the output channel FIRST, then push the input source you want to route from. A couple of reviews complained about all the output resolutions having to be at the lowest setting common to all. I found that not to be true. The resolution can be selected then “copied “ to an individual output channel. Bottom line, it’s pretty easy to use. I spent about an hour unboxing, reviewing the manual, hooking up connections and had it up and running very well. And I don’t have a lot of experience….

Old Switch went south requiring another unit to keep my AV system functional. Layout of plugs and such is the same making the swap out straight forward. This unit over the old is a significantly better build; more solid feel and function. Only glitch was the remote being DOA out of the box. Customer service is working the issue for a replacement, so am happy with all that. Great Switch - time will tell if it is better that the replaced one which died in two years or so.

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.

ATMOS is not mentioned anywhere in the user manual or specs or website. But I just hooked it up and it's passing ATMOS for me. Maybe they didn't pay for licensing so they can't advertise it? Or maybe it works but it's not supported and I may run into glitches, I don't know. But, so far so good. IR commands are available to download from the mfg's website. But I just learned the remote over to my URC remote and that was easier/faster to figure out. There are a few glitches when switching from my Nvidia Shield 4K to my HTPC 4K. But they are just a singular, momentary glitch. Could just be my setup. Someone in other reviews complained about how slow it is to change video inputs. That has nothing to do with this device. That's an HDMI 2.0 (and older) technology issue. Don't want to wait 5-6 seconds for the next display to come up on your TV!?? Then invest in the newer HDMI 2.1 spec. That one supposedly switches faster thanks to VRR. I really wanted to buy the HDFury VRRoom but it's more than twice as expensive. But if you can afford it, that's the way to go instead of this one. Another bit of misinformation in the reviews is that this defaults to the lowest resolution monitor in your chain. ROOKIES. Set up your EDID to the best monitor. Then for lower resolution monitors, set those outputs to "downscale". Right now, I have a 4K projector on one output. An analog audio extractor and a 1080P monitor on another output. On output #3, I have my 4K AVR. And on output #4 I have it set to downscale to 1080P and it goes to a second HDMI switcher which is connected to a 720P and a 1080P monitor. Works great! I'm getting 4K on the outputs configured for 4K and I'm getting 1080P on the outputs configured to downscale to 1080P. EDIT: It's giving me weird screen artifacts when I view my 4K HTPC computer as a source. If I remove the matrix, the artifacts go away. You can hardly see them, but they are there. I've ruled out cabling, etc. EDIT 2: I gave it a second shot. The second unit didn't have any HTPC artifacts. But I discovered the built-in EDID is not compatible with Nvidia Shield 2019 Pro as it only provides 5.1 and not 7.1 audio. The copy-EDID may be an option for you but that option always introduces instability in the long-term.

Purchased for our church in order to display song slides from our computer to 3 outputs: TV, projector, and a live streaming encoder (ATEM Mini). Pretty simple set up. About as plug and play as you can get. And after a couple afternoons testing it and one Sunday service, I have not had any issues with it and does what I hoped it would do. Our projector screen is 4:3, so I have to resize our computer desktop to 1280x960 so it all fits on the screen. I was concerned the matrix might get screwed up by that, but it appears to work fine. Build quality seems pretty good. My only complaint is that the remote does not appear to work, but that's fine as I don't really need it. Also, two thumbs up for customer service. When I first set the matrix up, it was not mirroring the computer and would only display when I started a slideshow with PowerPoint. I emailed OREI customer service and within a day they had gotten back to me. I had forgotten to ensure that my computer was mirroring. It had auto-selected to extend the display. I selected mirror and everything showed up as it should. Also, there appear to be many videos from OREI on YouTube to assist as well info on their website. Pretty happy so far for a piece of equipment just over $100.
