USB3.0 KVM Switch HDMI 4K@60Hz for 4 Computers Share 1 Monitor, KVM Switch 4 Port with 3 USB 3.0 Ports Share Keyboard Mouse, Support Button Switch, Plug and Play

I have been using this KVM switch, and it has worked very well for managing multiple computers with a single monitor, keyboard, and mouse. Switching between computers is quick and hassle-free, which helps me stay organized and work more efficiently. The image quality remains excellent, and the USB ports recognize devices without any issues. The unit also feels sturdy and well-built. So far, it has fully met my needs and has made my workspace much more convenient.

I have three computers: An older Win 10 (my primary machine), an older Fedora Linux, and a newer Win 11 Laptop. I *can* sort of switch between them to do most of what I want do using Cygwin from the Windows machine and ssh to create remotely and I already had a 2-way KVM. The 4-way switch now allows me to also access the laptop with a real keyboard and a much larger screen. I don't use the last port, but it does work properly. I used the extra (for me) HDMI cable to attach the switch to the monitor (bundling the wire) and can't find the the extra USB cable now. (I wanted to measure its exact length.) My older Win 10 uses a graphics card that doesn't have HDMI output, so I needed to get a DVI to HDMI dongle. While waiting for it to arrive, I used the Fedora as the primary. This worked out mostly OK, but not completely. When the dongle arrived I shut down the Win 10 machine, connected the monitor via the dongle, and restarted it. This sort of worked for a short time. The monitor was OK, but windows wasn't happy with the keyboard/mouse. These have a wireless connection plugged into the KVM. The mouse was erratic and would stop. Win 10 eventually complained too, and completely disconnected the USB port. I switched the connection over to port 4 and Windows complained that it couldn't handle it. I suspected that there might be a cable problem, but tried rebooting the Windows machine first. Voila, it started with no mouse/keyboard problem. I hot switched it back to port 1 with no problem. The new switch remained on during all this time. Maybe the Windows problem was due to having the keyboard and mouse connected (but unused) and not the video. I don't know, but there's no problem now, except: The cables are about six feet long, but that's a bit too short for one machine. I'd like the switch to be about an inch or two closer to the front of the desk. Now I have to reach under the monitor to switch. By the way, you *need* to attach the little plastic feet that come with the switch package to the bottom to keep it from sliding on your desk. The picture in the add shows the front and back side of the switch. It should just show the front side and the back side as an alternate picture. The switch is one box, roughly 8" wide x 3" deep x 1 1/8" high (with the feet.) The USB ports switch along with everything else so this is really a KVMU switch, obviously the U for USB. I like the switch, otherwise I wouldn't have spent an inordinate amount of time writing this review. It switches pretty quickly, less than 2 seconds. This is hard to measure exactly because it also takes some time for the OS to respond. I have to hold the switch when pressing the button to keep it from sliding, but I'm not switching often enough for that to be a real problem for me.

Setup: Literally a breeze. Plug everything in and it just works. No drivers or anything. Worked for me on Windows 10, 11 and several flavors of Linux servers. Performance: The switch handles video in an expedient manner. Meaning the switching between machines is almost instantaneous. I had no rendering issues such as screen resolution changes or color funkiness. There is no distortion when inseting this KVM into the chain. I have had other KVM’s where the mouse would lag a bit. That is not the case here. In fact, I was using a wireless mouse and had no lag. To switch machines it is a simple press of a button. Switching is quick and simple. Build: The KVM is made of metal! Nice as compared to a plastic alternative. Cables: The cables that come with the unit are functional, but you may find them a tad short for some applications. Fortunately 6 foot USB and HDMI cables are not expensive. However, in terms of quality the cables are good and present no issues. Conclusion: If you regularly juggle two or more computers at one desk, or have multiple servers in a closet this is the ticket to cleaning it up. Sharing a monitor between 4 systems is a worthy benefit. This unit is priced well and I feel it is a good value in terms of performance.

EDIT They've reached out and sent a replacement. Hopefully this one lasts longer than the previous one. Their support took a few days to respond but I appreciate them being so kind and helpful nonetheless. ----------------------- Worked great when I first set it up; it was the perfect solution for my home lab. Unfortunately it stopped working within a month. It can still switch display inputs but USB inputs stopped working. I tested different keyboards and mice and none of them powered on. I've reached out to support but no response yet. I will gladly update this review if they can provide support, but disappointed for now as I had planned to do some work on the homelab this weekend.

For the price, you simply can't beat this KVM! It has a nice compact footprint, is super-quiet (no cooling fans, etc.), transitions from session to session smoothly with little lag and uses standard USB and HDMI cables (no proprietary KVM cables needed). My main complaint is when switching from host to host the USB devices are connected/disconnected - this causes the sound for "USB Device Disconnected" to be played on the machine you are transitioning from, and "USB Device Reconnected" to be played on the machine you are transitioning to. Of course this is SUPER annoying, but you can turn off these sounds in the Themes on each of the machines connected to the KVM (unfortunately this will apply to ALL USB Connect/Disconnect actions not just those on the KVM). The sounds can be dealt with, but because of the way the KVM manages these devices you're going to see a LOT of USB Device Disconnect/Reconnect messages in your hardware audit log, and of course this introduces a slight lag when transitioning from session to session. My prior KVM (a Belkin F1DP116G) kept signal to the keyboard and mouse on each host machine active (whether USB or PS/2) so this was not a problem - if this KVM could do something similar it would be a HUGE improvement! Gripe #2 is the location of the 3 USB ports, they are all in the front of the unit. Meanwhile all OTHER cables connect in the back. I think it's great to have USB ports in the front for things you might want to plug in and take out (like a thumbdrive), but could you put at least two or three in the BACK so we can connect the keyboard and mouse (and maybe one other permanent device) in the back and not have their cables visible on the front of the unit? Lastly, the unit is powered by a USB-C cable to an AC power adapter. I have this plugged into a power distribution switch on the same circuit as my monitors. At the end of the day I flip the switch to turn off this circuit to power down my monitors and KVM switch - but the KVM still has power! It must be drawing power from the USB cable to one of the hosts (that is up and running 24/7)! It would be helpful if the KVM would power down when the power supply to it via the USB-C cable is terminated. Bottom line: Great value for the price, seems efficient and reliable - but with room for improvement.

The device is garbage! The front USB ports aren't functioning. While monitors switch correctly, the keyboard and mouse aren't detected. I tested multiple mice and keyboards, including high-quality cables bought for the KVM and the ones that came with it. Neither my 2021 MacBook Pro nor my new Mac Mini recognizes the input devices. I've checked security settings and other configurations; all devices work perfectly when connected directly to the computers. Unfortunately, there is no support available on their website, and I am left waiting for an Amazon chatbot to get back to me. I WANT to love this thing, and the size and monitor handling, as well as switching speed, are quite good, but if I have to manually unplug and replug in my mouse and keyboard every time I want to use the other machine, it is a waste of hardware/money.

I am a technical support person and requiring monitoring of several live client facing platforms. This KVM switch made my job so much easier, now with only one large monitor, single keyboard, and mouse I am able to do my job with one large computer monitor vs four screens! A real game changer for me because I can now switch between 4 different computers effortlessly with the push of a button and don’t have to slide back and forth to each computer. The push button switches quickly, smooth, and responsive. The real hidden benefit is set up with the plug-and-play which requires no effort installing extra software drivers or complications interfering with different levels of operating system. The USB3.0 KVM Switch HDMI 4K@60Hz (4 Port) provides 4K video with crispness and no frequency flickering response issues. In addition, the 3 USB 3.0 ports is beneficial for connecting peripherals like external hard drives, webcam, and printers – once connected all the devices can be shared. Overall, the price is competitive and construction of the KVM switch in rock solid and only requires a small footprint on your desk – not to mention it looks pretty cool – I highly recommend this for technical people trying to simplify their usage of multiple devices.

I’ve been using the USB3.0 KVM Switch HDMI 4K@60Hz (4 Port) for a few weeks now, and it has made my multi-computer setup so much easier to manage. With just one monitor, keyboard, and mouse, I can switch between 4 different computers effortlessly. The button switch feature is smooth and responsive, and the plug-and-play setup means no hassle with extra drivers or complicated instructions. The 4K@60Hz video quality is excellent—everything displays crystal clear with no lag or flicker. This makes it great not just for work but also for video editing and streaming where high resolution is critical. The addition of 3 USB 3.0 ports is a huge plus since I can share my external hard drives, webcam, and other peripherals across all devices without constantly plugging and unplugging. I also appreciate how compact and sturdy the build is. It doesn’t take up much desk space, and the connections feel solid and reliable. Switching between systems is instant, with no delays or disconnect issues, and the performance has been flawless so far. For anyone who works with multiple PCs or laptops, this KVM switch is a time-saver and productivity booster. Whether you’re a professional, gamer, or someone who juggles work and personal systems, it delivers exactly what it promises: efficiency, high performance, and convenience. Highly recommended!

I have 4 devices on this (one laptop, 3 PCs), three of which are 4K & 60fps, all plugged into a Samsung 32" 4K monitor (LU32J590UQUXEN if you're bothered). All devices have HDMI audio pass-thru which is running into the KVM over HDMI and back out of it to the monitor, then out of that via phono to a set of speakers. It all works well. This little switch (which incidentally is surprisingly heavy) handles it all. I think some of the people who complain about the switching delay are actually seeing their monitor reconnect, so it may not in fact be the KVM causing the delay at all, it may be the monitor. I had some oddness with the KVM until I plugged it into a 2A charger rather than trying to power it off the hosts. It will actually appear on, and will "work" off the PC USB power, but for it to be reliable it needs its own power source (not supplied with the unit). I used a phone charger. The LEDs showing which lines are connected (and that the unit has power) are too bright, I've taped over mine with insulation tape to dull it. I found one PC that didn't like the fact that my keyboard has a USB hub in it, which caused an issue as the KVM is *also* a USB hub. Unplugging the second cable from my keyboard (thus removing its hub) fixed this issue. I found the supplied HDMI and USB cables to be too short, so I used other ones I had laying around. The supplied HDMI are just regular ones, around 1m long. I replaced all 5 (4 to hosts, 1 to screen) with 2m HDMI cables I had. The supplied USB KVM to host cables are USB-A at one end (the switch end) and USB-B at the other (male at both ends), again only around 1m. I mention this because in 2021, USB-A is prehistoric; if you want a cable longer than 1m you'll likely need to buy it separately. I was lucky to have a load of old ones. Surprisingly good little device for the money. I paid £70.

I tried and send back a few HDMI KVM switchs claiming to support 4K but unable to handle 1920x1200 resolution (16/10 format so appreciated for photo editing). This KVM does it very well. Then, the only missing feature is the remote control meaning the box is to be located on the desk to be accessible. Apart from this, this is a nice device.

En comparación con un viejo KVM VGA(RGB analógico) al que sustituye, las mejoras saltan a la vista. Una mayor capacidad de resolución para soportar el cambio de monitores al que está destinado , (aunque los conectores son HDMI 1.4 soporta la transmisión HDMI 2.0 de alta resolución). Los diodos led excelentes y muy bien posicionados estéticamente. El Hub para 4 dispositivos USB tiene un pequeño inconveniente como que debería tener 2 entradas B de conexión en la parte frontal para compartir dispositivos Usb, (como pendrives etc.), y las otros dos para el teclado y el ratón detrás, formando parte del cortejo de conexión REAR de los conectores A y HDMI. Los cables suministrados no tienen una longitud excesiva pero son de calidad. No haría falta alimentarlo a 5v. pero yo utilizo el cable de alimentación suministrado para introducirlo en una ranura usb y así alimentarlo desde el PC ya que no trae fuente de alimentación. Por lo demás muy bien. Excelente relación calidad precio, Lo recomiendo para utilizar cuatro ordenadores a la vez con un único teclado y ratón y añadir la posibilidad de extender tus escritorios o pantallas para los 4.

Benutze die Switch um ein MacBook M1, ein HP ZBook mit Linux und ein Lenovo mit Windows 10 mit meinem externen Bildschirm zu verbinden. Benutze für alle Laptops die selbe Maus und Tastatur. Das hin und her schalten funktioniert super. Die Qualität scheint auch solide zu sein. Die Buttons und die Haptik fühlen sich hochwertig an und haben einen spürbaren Druckpunkt. Einziges Manko, wenn man die Switch ausschaltet, funktioniert sie zwar nicht mehr (wie gewollt), allerdings leuchten die Buttons noch. Das ist etwas störend in einem dunkeln Raum in dem man auch schlafen möchte.

Que ce soit pour du télétravail, geek ce genre de produit est excellent vous pouvez brancher consoles, pc lecteur/blueray/DVD et tout contrôler avec un clavier / souris ( quand le device le permet ( console pc etc..) vraiment un gain de temps et de place
