OREI SplitExtend HDMI Splitter Extended Display for Quad Monitor - 4K@30Hz | Multi-Monitor Display 5 Separate Screens - USB-C Adapter to HDMI 2.0, 4K@30Hz Outputs - Windows and Mac Compatible

I love my Mac and buy a new one every 5 years or so leaving me with a working "legacy" model cause Mac's die tough. The one in my picture is a 2019 MacBook Air in a 13" model. So the native capabilities of this Mac for multiple extended displays was natively limited to one. Not sure if the limitations of the video card or it only has (2) thunderbolt ports and one is the charge port. Anyhow, I have (3) monitors from my work setup having recently retired and wanted to put them to use as they are fairly new 32" curved monitors. Very simple to setup and to my surprise, worked like magic even on the older limited video capabilities of my old Mac. I see some who left mixed reviews and I was hesitant but did not see much in anything even close with (4) extended screen plus use of my laptops screen (so capable of (5) total screens!). Especially not at this price. I am completely thrilled. There is a little flicker or buffer for a couple seconds only when I first wake up my laptop while it allocates the signals to generate the 3 screens I'm using but it's brief and then it does not do it again. Works fantastic for me. Super fast shipping. Amazon has a great policy with vendors for return and I have always been happy with Amazon, so I decided to purchase and am completely satisfied, thrilled matter of fact. Great product, great solution. I was not payed or otherwise received anything for this review but when I find a great product or get great service, I take the time to say so. Super fast shipping too

So far I am very happy. I have this running three displays for my Mac Mini M1 and Thinkpad E16. Four displays for the ThinkPad if you include the laptop screen. It seems well made, it was nicely packaged. The quick start guide was well written, and it works! The host cable could be a bit longer. Historically I am a PC guy. I've been computing on Windows since Windows 2.0. I teach Computer Science and Cybersecurity in college and typically have a bunch of students on Macs who sometimes struggle getting some software packages installed and running properly on their Macs. I could help, but I didn't have the experience on a Mac that I do on a PC. And my wife is a Mac girl, always has been. So I finally took the plunge and got a renewed M1 here on Amazon not long ago. It took a little while to get it set up so I like it, but I do. The problem is I like multiple displays. And I wanted to bounce back and forth between the Mac and the PC. I bought a Lenovo specific USB-C dock which worked great for the PC, but the displays were mirrored on the Mac which is useless for computing. After a little bit of reading I decided on this product. After driver installation, which was a breeze, I plugged everything in. I have the three HDMI cables plugged into the adapter and I have that plugged into a 10 Gbps port on the Lenovo dock and it worked! To move between both machines I have to move only one cable. There are KVM switches that would work, but they are quite expensive. So I will use this for now and see how it works out. SO far I am very happy with it.

Unit wont stay connected. - it was very easy to install and worked right out of the package. It worked for the first few hours of my shift then started to disconnect. i have tried all the different connections, different cables and ports. Not sure why it disconnects. first day ran for 4 hours, day to took me an hour just to get my screens on. it goes in and out so bad now i had to remove it and I am researching different products.

Small compact and works just great

Works as expected, very useful. The only downside is that it heats a lot, if you touch it, it's burning even with the screens in rest mode. I guess that's its natural way to dissipate heat, since it doesn't have a cooler; but it's a bit concerning that it's going to be working almost all day burning from the moment you turn it on.

I spent a lot of time and effort looking to use multiple monitors for my old laptop. What I didn’t know is I needed a device that will both split and extend my laptop screen. There are splitters, and there are extenders. Splitters simply duplicate the same machine like you’re watching a demo in the TV store. But extenders actually make your original screen bigger and it can be used on multiple screens as in move a program to one screen move a different program to a different screen and so on and so forth. I wish that there were a cheaper version because I paid over $90 for this one, but it does what it needs to do.

Worked mostly ok for about 8 months, with the only hiccup being how fast it heated up, and the occasional switching of screens. An external fan took care of the heat issue, and unplugging/replugging the USB resolved switched screens. However, it just died on me now out of the blue. Useful while it lasted...

This setup has turned what was an amazing setup before (triple screen) into NASA or Control Room territory. This setup allowed my workspace to have 5 displays extended - all independent of each other! My setup is a 2x2 array plus one larger screen to the right (my screenshare screen). So much easier to keep control of everything I have to manage on my screens during my workday! And you can control them in groups of 2 or all 4. Super easy to work with - download went really easy and is super quiet. Very little lag. I'm usually using all 5 screens all day long. The size of this device would fit in one hand, maybe half an inch high. Do make sure you have a power connection directly to this splitter/extender. I had a COX representative here earlier this week who was absolutely amazed at my setup!

Not happy at all. It worked fine for a couple of weeks but then displays started not coming on and then they would randomly blink off and on. I went to pull the cord out to try in a different USB-C port and the whole tip pulled out of the housing. I tried using just the USB three and but none of my displays would come up. I noticed also that the unit was very hot to the touch.

This is awesome. Please go for it and it's working on Mac & Windows. Mirror - Yes Extend to all the 4 external monitors - Yes. Hence cumulatively, we're getting 5 different displays.

It works well at the start, connected 3 monitors, using factory USB power, but overheats, even in AC. I have installed aftermarket heatsinks on the exterior, but still is hot to the touch. It's been less than 2 months and the device doesnt turn on. All earthing, power supply, etc. are proper. I can't even return it. I need it to be fixed, but there is no number to call.

Deserves no stars at all. It heats up with five minutes of use, then the display colour begins to switch from pink to yellow, after which it begins to go off and on in the middle of important work until finally it dies on you and will not come back on - no matter what. All under one month. Making contact with Oreo, fingers crossed, they'll remedy the situation...it's quite pricey for such a poor experience

every 15 minutes it blackouts and restarts all screens…
