MT-VIKI 4K HDMI Multi-Viewer 16x1 w/IR Remote, 4K@30Hz Seamless HDMI Switcher 16 in 1 Out for PS4/PS5/Security Camera

UPDATING MY REVIEW TO 5-STARS! The tech support offered was exceptional! There are a few things you should know about if you have issues: 1. This will ONLY work out of the box on a monitor that supports 4k resolution! You will need to adjust the resolution down hitting one of the hotkeys, in my case - to adjust to 1920x1080 @ 60hz I had to hit "Home+Home then H and 2" on my keyboard. It then displayed ok! 2. For the hot keys to actually work, you MUST plugin your keyboard into the BACK keyboard port and NOT any of the front USB ports or your commands won't work! I'm very used to plugging into front ports as I have a laptop dock with front keyboard/mouse ports and am very used to that. 3. Watch the video to find out how to display the dual and quad configurations on-screen! They are NOT in the manual that I could find! This is a very GOOD product and I hope the instructions become clearer in the future!

I run a small analog-to-digital conversion business that transforms old home movies from tape media to digital formats. I needed a way to not only monitor multiple projects at the same time, but also control the computers with a single keyboard and mosue as well. This multi-viewer was the answer. Each of the 4 inputs has an HDMI and USB connection that is run to 4 Micro PC computers. I have a wireless keyboard and mouse connected to the dedicated USB ports on the back of the unit and when the input is switched, the screen changes to that computer and the keyboard and mouse are instantly connected. There is NO lag. The front buttons change the input but I do not use them, There are hard-coded keyboard shortcuts that control the unit. While a little tedious at first, hitting Home Home M 0 pulls up the current input full screen, while Home Home M 2 pulls up all four inputs in multi view. (See images). There are more commands with different PIP and screen assignments, as well as commands to simply change the active input on screen. I can highly recommend this item simply for its functionality, but when adding the solid build quality and durability as well, this is a no-brainer for the multitasking professional or enthusiast.

Does the job.

Works decent switching between computers. However, when I choose a mode such as PIP, so I can have a small window showing what is on the other PC, the main window PC gets very fuzzy. No fun seeing fuzzy letters.

Bought this as a multiviewer for GameCube LAN games, the multiple viewing options are very handy for when I'm running 4 or 8 consoles! Latency in a multiviewer mode appears to be acceptable for gaming which is a bonus. Note: The multiviewer does not have a mode for displaying 5 HDMI inputs (4 small 1 big), but all of the other modes are very useful.

Working great, take your time and follow instructions.

Works very well as advertised. Has a very crisp and clear picture. Switches between computers pretty fast (about 1 second).

so.. I own 3 hdmi multiviewers. 1 paid $240 for the best one I have, which was worth it. I paid about $50 for the worst one I have which is blurry, not truly 4k even though it claims it was. And this one is priced in the middle of that, which is fair, since I would rate it as the mid quality product. In fact I would say that many sellers would try to sell this one for perhaps twice as much since it does work well as far a picture quality and also no lag for gaming. It does not have as many useful features as my top of the line one does. not as many screen configurations that I would like. But like I said, for the price/quality ratio, this is probably your best bet.

問題なく使えています。ちょっと操作に対する反応が遅いかな。

This HDMI Multiviewer is an excellent solution for anyone looking to manage multiple HDMI input sources on a single UHD display. With support for up to four HDMI inputs and real-time seamless switching, it provides a versatile setup for home entertainment. The device handles resolutions up to 4K, ensuring crisp, high-quality visuals while offering backward compatibility for lower resolutions. We're using it to switch between our projector, Chromecast, XBox and Blu-ray player, so we don't have to keep plugging in and unplugging things when we need to switch between devices. The multiviewer has four display modes: Single Mode, Quad Mode, PBP (Picture by Picture) Mode, and Dual Mode. These modes let us custominse how we view the inputs, from seeing all four sources at once in Quad Mode to isolating one in Single Mode. It's worth noting that audio output only works in Single Mode and PBP Mode, while the other modes are muted, which could be a limitation depending on your needs. For us, we just find it an easier way to look across our devices, so the lack of sound makes no difference. Switching between devices is smooth and can be done in two ways: via the press of a button on the device or using the included remote, making it convenient for us to switch between them from the sofa. Its compatibility is big plus for us, as the multi-viewer supports a wide array of HDMI devices, including gaming consoles like PlayStation, Xbox, and Nintendo Switch, as well as media devices such as Roku, Fire TV, and Blu-ray players. You receive everything you need to get started, with the HDMI multiviewer, power adapter, remote, and user manual all included. Overall, this HDMI Multiviewer is a solid, user-friendly device for anyone who wants to streamline multiple HDMI sources into one display with ease and flexibility. Highly recommended.

Die Lieferung war unbeschadet und Amazon üblich sehr schnell. Der Switch ist hervorragend verarbeitet. Die verwendeten Materialien sehen und fühlen sich sauber und hochwertig ausgewählt sowie verarbeitet an. Das Metall wirkt sehr edel beim Anfassen. Das Gerät ist ideal um Endgeräte mit unzureichenden Anschlüssen zu erweitern, insbesondere liegt das Augenmerk auf das Teilen von Monitoren und Peripherie mit bis zu 2 Ausgabegeräten. Man kann 4x HDMI Geräte damit verwalten. Somit kann man mehre Quellen über ein Ausgabegerät steuern. Also reichen auch ein Maus/Tastatur-Set um mehrere Rechner bedienen zu können, was über diese Box ermöglicht wird. Über die Anschlüsse lassen sich zwar 4K aber leider nur bei 30Hz betreiben. Das ist für Gamer kein guter Kompromiss. Wenn man mehr FPS braucht, dann ist der Switch nicht zu empfehlen. Dafür lassen sich aber 4 Endgeräte damit verwalten. Audio hingegen lässt sich hierüber nicht übertragen. Da fehlen die Anschlüsse und die entsprechenden Funktionen. Somit kann man leider kein Headset mit 4 Ausgabequellen verwenden. Verzögerungen beim Umschalten sind zwar vorhanden, aber im erträglichen Rahmen. Der Preis für den Switch ist wohl gemessen an den Funktionen und der Qualität gerechtfertigt.

Essentially, what this does is allow you to easily switch between multiple HDMI devices using one monitor. This means that if you have only one or two or three HDMI ports on your television/monitor, you can boost this by 3 (because the switcher itself obviously takes 1 and so you get a net gain of 3). What is really cool about this though is that in addition to the switching, you can have your multiple devices plugged into the switcher on the screen at once. Primarily, this is going to be useful for CCTV, but you could actually use it to watch multiple sporting events, as an example. Usage is very simple. You just need to plug your devices into this device and then plug this device into your screen/monitor. Put the power cable into the device and you're set up. The included remote allows you to switch between devices and modes. This remotes is a little cheap looking, but completely functional and fit for its purpose.

条件（異なる解像度＆Hzの組み合わせ）によっては、うまく表示されないパターンがあり、 全体がノイズとなる。原因を探るのに微妙に苦労した。 ただし、条件さえ守れば、問題なく使用できたので、まぁ～いいかな？ はずれ個体の可能性もあるが、表示されるパターンもあるとなると 多分、仕様なのだろうと思っている。 対応範囲内の解像度ではあるので、そこはうまくやれよ！と思ってしまい、評価も普通以下かな？と思います。
