OREI HDMI Switcher 4 in 1 Out with Quad Screen Multiviewer - Supports 1080p, DTS/Dolby Audio, IR Remote Control, Seamless Switching, Compatible with HDMI Devices

I love this product! I use Hulu Live TV with the unlimited screen option because I tend to use the Disney+/ESPN+/Hulu suite quite a bit, so it's a better value for me than YouTube TV. But YouTube TV does have one feature Hulu lacks, multiscreen view for sports. However, even that doesn't solve the Thursday night problem where NFL is on Prime, so I was looking for a device where I could provide multiple inputs and show them on the screen at one time. For this purpose, 1080P was fine, and this device does it perfectly. But the remote doesn't cover the full functionality of this device, especially when it comes to switching which window is providing the audio at any given time, the remote only allows you to cycle through the inputs (you can't pick the 3rd input directly for audio, for instance). However, this capability did exist using commands sent over the serial port interface on the device. So I got OREI's serial cable and hooked up the device to an old linux laptop and played around with issuing commands. I very quickly evolved that into a fully functional iPhone web app interface (pic attached) and have it running on a very small Raspberry Pi zero connected full time to the device. I now have tremendous flexibility and functionality, where I can quickly switch modes, switch audio, and swap windows. Hopefully OREI offers a device in the future with wifi and app capability built in, it's a game changer! I will say I tried this model (supports up to 4K@30hz) and the next model up that supports 4K@60hz. The more expensive model did support the 4K@60hz resolution, but it didn't support Dolby Atmos, so since I would have to downgrade on the audio I decided it was okay to limit myself to 4 1080P devices and basic 5.1 sound. I didn't try the cheaper model that supports only 1080P because I was so satisfied with the capability to configure this model that I stuck with it.

bought the OREI Quad Multi HDMI Viewer 4x1 Out HDMI Switcher because I’ve been really disappointed that so many new TVs don’t include true picture-in-picture anymore. It’s frustrating, especially if you’re a sports fan who wants to keep an eye on multiple games at once without constantly flipping inputs. This OREI switcher ended up being exactly the kind of solution I was looking for. It gives me the ability to connect multiple HDMI sources and actually see more than one feed on the screen, which brings back a feature that a lot of modern TVs seem to have abandoned. The product is sold as a 4-in-1 multiviewer/switcher with quad-screen capability, and current listings show it around $44.99 with a 4.9/5 rating from 15 reviews, which feels like a great value for what it does. What I love most is how great this is for the sports fan in your life. On game day, being able to watch multiple matchups, keep one screen on the main event, and still monitor other games at the same time is a total game changer. Instead of wishing my TV still had built-in PiP, this gives me a practical workaround that actually feels better because it’s designed specifically for handling multiple HDMI sources. OREI’s multiviewer listings note support for up to 4 HDMI inputs, multiple viewing modes, 1080p support, and audio formats like Dolby and DTS, so it really does fit the use case for cable boxes, streaming devices, game consoles, and other sports-viewing setups. Setup was straightforward, the switching is smooth, and the multiview feature is the real star of the show. If you’ve been annoyed that TV manufacturers keep removing features people actually used, this is one of those rare accessories that solves a very specific problem really well. Overall: If you miss picture-in-picture and want a way to watch multiple games again, this is an awesome buy. It’s a smart gift for any sports lover, a great workaround for modern TVs, and one of those gadgets that makes you wonder why TVs stopped including this feature in the first place.

This HDMI switcher is a great solution if you have multiple HDMI devices but limited inputs on your TV or monitor. It allows you to connect several devices and switch between them easily without constantly unplugging cables. One of the standout features is the quad screen multiview option, which lets you see multiple HDMI sources on the screen at the same time. That’s especially useful for monitoring different devices or setups. The included remote control makes switching inputs quick and convenient, and the signal quality stayed clear during use with no noticeable lag or loss in picture quality. The device also handled audio formats like Dolby and DTS without any issues. Overall, this is a solid HDMI switch if you need to manage multiple HDMI devices and want the added flexibility of a multiview feature.

Overall it works great. I can watch multiple shows or sports events at one time. The video quality is great. I only deducted a star because the controller is a little wonky but overall it’s worth it.

I have only had this for a few weeks, and I like to use electronics for at least a few months before reviewing, but I will come back and edit if it just glitches out on me. The pictures shown in this listing (as of 02/23/2021) are incorrect, and do not depict the HD-401MR. Half of them are shots of the newer unit, the HD-401MV. The MR does NOT have a VGA output and much simpler and less versatile controls. You can see the model number right on the unit in the pictures, so I bet someone who does not read english characters is to blame. If you expected to get the VGA input, I'd complain to Amazon; I think that legally they have to honor the sale of the product shown in the listing. EDIT: I just noticed that now ALL of the pictures are of the MV (with one VGA output added) unit, none of the MR (HDMI only). The made it worse! I don't know why they'd do this. If you want the MV for the price of the MR, buy from this listing! If they send you an MR, demand an MV because that's what they advertised! They have to honor their advertisement and not simply refund your money. They deserve this for not keeping their house in order. By the time you read this, they may have corrected this issue. (Nope.) If so, I can say that this is a decent unit. I only needed to be able to show four displays on one, and switch to just one display occasionally. It does this perfectly. Two of the inputs are the main screen and an additional monitor for a desktop. I can arrange to displays on the system to match the one-over-the-other configuration I get on the monitor, so I have no issues with moving the mouse between screens. I'm taking off two stars for the pictures of the wrong model in the listing. But I would have taken one star off for the almost worthless other display options that are available. They all change the aspect ratio to fit the area they designed, and who needs two screens in the middle with two tall but ultra-squished frames on either side? I think they could have come up with some better configuration options given the same effort, such as: Picture-in-picture: One input fills the whole monitor in proper aspect ratio, with one input covering one corner, with the ability to chose which corner it covers. Three-on-one-side: Similar to an option they have, but done while maintaining the aspect ratio of the larger image, and the ability to switch the sides that the three monitors are placed. Just some suggestions. Perhaps when this review reaches corporate headquarters they'll contact me for a consult. The big takeaway: maintaining aspect ratio is something customers want.

This switcher is now an essential part of my small studio. Gradually I had been accumulating small HDMI monitors for various projects. This now shows all 4 images on one screen, and gets rid of the small pile on monitors and cables that littered my desk. Problem solved. The switchover was really easy, just a matter of plugging it in. I'm using it at 1920 x 1280. I was surprised at the low cost, and the excellent picture quality. It comes with a couple of accessory ears for mounting and the construction is very solid. Recommended.

I needed a 4K multiviewer to watch data channels and tracker data for F1 races. This box allows pretty much all combinations of screen outputs from 1,2,3 or 4 screens which is independent on each output. Picture quality is great with no noticeable difference or lag from direct display. Several people have commented on no HDR support and I can confirm this - the two YouTube stats for nerds images from my 4K max fire stick show BT709 with the multiviewer vs full BT2020 direct. However, with this limitation, and the poor quality remote, the unit itself is really very flexible and functional. I saw a comment about stretched images but you can select 16:9 to correct this (see example images in full or 16:9 modes). To switch which hdmi input is the main screen, you need to go into the menu opts for that output, but it can be done (see menu image). Audio can be muted or selected from any feed or each output. For the price, this is excellent and only the lack of HDR is missing. However, HDR units seem to be many hundreds of dollars more. I would recommend.

In a world of streaming this multi viewer is amazing. The only thing that could be better is the remote. It's a little small, flimsy, and sometimes you have to press the buttons multiple times to get the action you want. I have four Roku sticks hooked up (needed some HDMI extenders to get them all to fit in the ports next to each other). I control the Rokus with the Roku app on my phone so there's no cross talk. Now I can stream a game on Prime or Peacock and have other games on YouTube TV and switch between them seamlessly with the multi viewer remote or have multiple games up at once.
