Cable Matters 20Gbps USB C Switch for 2 Computers, Up to 8K@30Hz on Windows, 4K@60Hz on macOS, 140W PD, for Sharing a USB-C/Thunderbolt 4 Monitor or Dock (Not for Dock with an Attached Cable)

i have an HP work laptop and thunderbolt 5 Mac mini connected to an older (discontinued) thunderbolt 3 Mokin dock with Pebble usb speakers, mouse, keyboard, webcam, scanner and output to dual 2k monitors via displayport... and this switch works PERFECT. this is the WFH dream setup, and allows me to flip from laptop to the Mini for $60. the trade off is that i had to provide separate power to the laptop so that it keeps getting power from somewhere after i have switched away. I already had an Anker 240w charger for that. if you have a dock that works with two computers and you just need to change the ubc-c cord... this switch "should" work to make that dock switch to either computer with just a button push. then you just need to solve for constant power to each machine, because the power would switch too. i spent two months trying and returning 5 different KVM docks priced up to $500 and not a single one worked right, and this little beauty works for a fraction of that price!! im so impressed. piece of advice-- i tried a different (longer) thunderbolt 4 cord from the switch to the Mini and it did not work... it was a Silkland cord, perhaps those cords are not up to spec? but the shorter cords that came with this switch do work, so i had to rearrange my setup to make the short cable matters cord work (not a deal breaker for a mac mini, which is small enough to be moved around) i cant say this enough-- forget the KVM options out there. i spent probably 100 hours researching and never found one that worked for me, despite using chatGPT for tips and reading thousands of reviews from actual users and "Vine" reviews. KVM seems like such a simple idea... but they just dont work 100% for some reason. The mouse or keyboard drops out, flickering monitors, dropped handshake protocols... and issues came arise months after purchase. for that kind of money they need to work better. fortunately, this little switch did exactly what i need, for a dream price. Thank you Cable Matters!

The Cable Matters 20Gbps USB-C Switch turned out to be exactly what I needed for my dual-computer setup. I use both a Mac and a Windows work laptop, each with USB-C display output. I’ve got my keyboard, mouse, and desk light all plugged into a USB hub on the back of my monitor, and I simply velcroed this switch to the back. When I want to swap between my Mac and work laptop, I just reach over and press the button — it switches over in about three seconds, which is totally fine for me. The remote control works too, but since I’m sitting right in front of the monitor, I rarely use it (it might be perfect for other setups though). I originally bought this on a whim just to test my idea, and it turned out absolutely perfect. For the price, it beats a lot of expensive KVM switches. The good Seamless switching between Mac and Windows laptops Only a brief 3-second delay when switching Compact and easy to mount behind the monitor Works great with existing USB hubs and accessories Excellent value compared to full KVM switches Would be nice if it came with a small combo USB-C/USB-A hub included Overall If you have two computers with USB-C display output, this is an awesome little device. Clean, affordable, and works exactly as expected. Perfect for dual-computer with usb-c display output productivity setups.

The switch works as advertised but the remote never once worked. However, I reached out to Cable Matters and received a prompt response offering to send a replacement remote. Will see if/when I receive the replacement remote if it will work and adjust my review accordingly. Edit 3/26/2026: Received replacement unit from Amazon. Both switch box and remote worked out of the box adjusting review to 4 stars.

This USB-C switch has been an absolute game-changer for my setup! I've been using it for about a year now, and it seamlessly connects my multiple computers to my external monitor rig. Switching between devices is incredibly smooth and hassle-free, saving me so much time and frustration. The performance has been consistently reliable, and I haven't encountered any issues at all. Honestly, if you're juggling several machines and need to connect to a shared display, you absolutely need one of these.

It works fine. The remote, however, is useless. It burns through the battery in less than a day. Apparently, I can replace the 2025 battery with a 2032 and it is supposed to last longer. But capacity of a 2032 is at most 50% more than 2025. So I'll get 15 hours instead of 10?

Extra steps and equipment needed for DisplayPort Dell Monitors. This device works as the description states except when you have two DisplayPort Dell monitors, the monitors disconnect when you switch computers and fail to reconnect. This is because when you switch, the KVM resets the docking station at the host port and cannot stabilize the EDID connection, because some monitors like Dell do not have enough power to keep the displays connected. The expensive work around is getting the Lindy DisplayPort 1.4 EDID Emulator (32118). This EDID emulator connects to your docking station DisplayPort, then using a DisplayPort cable to connect from the EDID emulator to the monitor. This keeps the monitor always connected even when pressing the KVM to switch computers. I gave it only three starts for my exact issue and expensive work around since I only have DisplayPort. I needed up having to purchase to emulators at $254. Though, I want the option to be able to switch back and forth when working from home to my personal computer so it is what it is. I wish they made this in 40GBps which may have helped my case and saved me money.

I am currently using 1 external display for both Macbook Pro (M1 Pro) and Mac Mini (M2). Even though I can switch all devices such as monitor, hifi system keyboard and mouse by just connecting 1 thunderbolt cable, but it is still a hassle. However, it took me a long time to look for a KVM switch that can support faster than 10gbps as most of the KVM switch in the market only support up to 10gbps. Until one day I came across this CableMatter 20gbps switch, it solved all the problems that I had by manually unplugging and plugging in the thunderbolt cable to different devices and it has been work flawlessly for after a year of usage.

I had to change my review. Initially, it did refuse to start then after two days it stopped working. It turned up that the cable supplied are or became very directional. Yet, there is no indication of that on the cables themselves, the manula, the web page, the Amazon page, unless I missed it. The main thing is that now it works flawlessly! It is now connected to an old (but absolutely wonderful) Apple Cinema display ca. 2011 by two extra adapters (The Apple display crazily has a non remomovable mini DP only (told you that is an old display). At the other end is connected to a Macbook Pro M4, and the other system is an old MacBook Pro 2016 running WIndows 11 through Bootcamp (or sometimes booted to Monterey). It has been working now for two months, switching seamlessly for two months (of course now I marked the ends odf the cables!). My apologies to Cable Matters, and a plea to mark the seemingly directional cables so that they can be correctly connected and explain that in your instructions. I was tempted to give less than 5 stars, because of that, but it does exactly what I need, hence 5 stars.

RESUMEN: Funciona perfecto, ideal si quieres cambiar rápido entre dos portátiles. Funciona con vídeo y carga. Tengo un monitor que conectaba con un cable USB para cagar y tener video a la vez en mi portátil personal. Quería poder intercambiar fácil entre mi portátil y el del trabajo sin tener que cambiar el cable. Ahora tengo ambos portátiles conectados al aparato, y éste conectado al monitor, con un click en el botón físico (o los botones del mando) me cambio rápidamente de uno a otro. Tarda alrededor de unos 5 segundos cambiar de uno a otro, nada dramático ni para bien ni para mal. Creo que solamente carga el portátil activo, pero no he hecho pruebas para corroborarlo.

Fonctionne bien mais sur mon Dell inspiron 7640 il indique souvent charge lentement alors qu'il est sur secteur. Mais sinon c'est exactement ce que je recherchais

I currently have it setup with a Wavlink triple display dock (DisplayLink) with 2 1080p monitors connected to a Mac Mini and a Mac book pro. I can confirm this setup works for dual monitors. One important thing, make sure to use the included usb4 cables. I have tried to use a longer 2M 40gbps/240W usb c cable because the included ones are a little too short for my setup. This doesn’t work as I believe the cables quite different. If you do want to have a longer cable you’ll really need to do a bit more research and find a suitable 20Gbps USB4 cable possibly from the CableMatters brand themselves. I believe USB4 also has a length limit for passive cable and signal lost can occur which for me causes my monitors to flicker on and off. The included shorter cables does not cause this issue.
