4 Port Dual Monitor KVM Switch HDMI 4K60Hz with Cascading

I run 2 devices at home, one is a linux desktop with a Windows VM for gaming (GPU passthrough), a Macbook pro 2019 and a Macboook Air M2, the laptops are connected to a USB dock and it works well with dual display (yes, even for Mabook Air M2 using InstantView). It takes around 3 seconds to switch from one device to another and as advertised due EDID emulation the devices keep their windows in place as the monitors were still connected. The keyboard and and mouse feels instant as soon as you're able to see the screen. I have two asus monitors 1440p and so far, on the HDMI cable I succesfully were able to run it at 144Hz. I also tested with two active DisplayPort to HDMI cables and they work without issues (new computers usually comes with just a single HDMI port) and also tested with USB-C to HDMI cable and worked very well. Currently

I have a wireless dongle for a Razer Pro Type and a directly connected Razer Pro click, I used these before the KVM as they allow you to switch between devices but the mouse ended with faulty bluetooth and this KVM solved all the inconveniences of changing inputs on every monitor and switching bluetooth mode on each device, It feels amazing and truly improves multitasking being able to easily switch everything with a single button. Even in passthrough mode, it's easier to switch between devices with key shortcuts. The operating systems properly detects they're the advertised devices and so far, the multimedia devices and the additonal mouse buttons work well.

I used a couple of times split displays and works as advertised, no much to say about this, I would say it depends more on how you handle your devices if you can take advantage of this feature or not. The frontal USB port is connected only to the device you are attached so be careful when connecting storage devices as they are disconnected from one device to another when switching. It works well so I think it's useful to have an extra usb port that directly attach to every other device.

The device feels sturdy and doesn't take too much space, its like the size of a tenless keyboard but taller, and can be easily accommodated below a monitor if you have a mount. Not exactly an apple looking device but definitely a lot better than a cheap plastic product. It comes with all the cables needed for connecting your devices and this helps you to make this work out of the box very easy.

The cables are great and feels they're good in quality, however, I have my devices at different distances and a couple of them feels a bit short in order to do some cable management (for example passing the cables behind my desktop or placing my laptops far from the KVM.

Overall, for those who seek doing VM without the complexity of software switching them, or adding physical devices this works great. I would say overall if you have pletora of devices going with the HDMI version is better as it's easier to find adapters for Apple devices that use hdmi and it's easier to find HDMI on TV and consoles.

This KVM is well worth the money. Now it doesn't have USB 3 so I can't say its the perfect KVM for me, however other than that I have nothing bad to say about it.

I run 3 computers at home, one windows gaming rig, one linux server, and one Mac OS laptop from work through a USB C dock. All three have no issues with this KVM which is awesome. I used to have dual monitor DVI setup for them, until I upgraded my monitors. I needed to find a new KVM to deal with the HDMI (or Display Port) connections on the new monitors without a bunch of converters.

I started with a cheaper 4 port dual HDMI KVM, however I grew real tired of there being no EDID emulation. That led me to this model. This is a really great KVM. It supports my new 2K 144hz monitors with aplomb, has no issues with my MS Natural 4000 keyboard (in terms of extra functions) and switches fairly quickly. The EDID emulation means my screens don't revert to single displays when not the focused machine. All the good things I missed on the cheaper one I picked up.

There are a few things I miss from the DVI one I had. For one this one does not let you switch the USB hub independently (at least that I can find) which is nice some times if I want to list to a meeting on my work computer but check something on my server (I use a USB Audio card plugged into the USB 2 hub on the KVM). The other thing I miss is with the old KVM I was able to reset the USB switch via keyboard shortcuts. This makes it easy if something doesn't catch properly after the switch (looking at you again USB sound)

Overall I think this model does the right things and is worth the money, as to get the perfect KVM (at least in my opinion) it would be at least twice the price and I personally don't have that kind of budget.

This dual monitor kvm switch works as advertised. I’m running a Mac Mini personal computer, HP laptop work computer and HP desktop side business computer though it into two external monitors, printer and and webcam & it’s all works well. If you want to run 3 or 4 different computers into the same two monitors, printer and webcam, this will do well

Works exactly as expected. You can display one computer per screen and the keyboard and mouse smoothly shifts between them.

Bit expensive but worth it if you need it. The only difficult thing to work with is the way you select which monitor displays which computer. It is simple once you practice pressing the display button and desired input button quickly.

I use it for work, so it has a server, and three laptops connected. Basic Logitech mouse/keyboard combo. Simple 1080 hp monitors. I even use some hdmi to dp and hdmi to usb c converters, works great.

This KVM switch was extremely easy to set up. Just make sure to follow the instructions exactly. I use the product for 3 different laptops; 2 of the laptops only use 1 screen and my work laptop uses dual monitors. For the dual monitor, my laptop does not have an HDMI port. So I'm using a Belkin Thunderbolt splitter which works seamlessly with the KVM switch. The only thing I don't like is the number of cables I have to use; 1 HDMI cable per monitor, 1 or 2 HDMI cables for the laptops (requires 2 HDMI cables if you extend or duplicate the screen from the laptop to 2 monitors), and a USB cable for each laptop. This particular KVM also has a USB 2.0 port on the front so I can connect my USB keyboard/mouse to share across the devices. The switching happens almost instantly. Sometimes it takes the monitors a few seconds to wake up.
