ROFAVEZCO 4K@60Hz HDMI 2.0 KVM Switch 4x1 for 4PC Share 2 Displays and 4 USB 3.0 Ports SPDIF L/R Audio,Copy/Extended Mod compatibile with Windows, Unix and Mac OS X

I've used KVMs since my PC tech days when all the server stacks used them, so I'm pretty used to the setup and care needed. This one is pretty darn simple, but has some nicer features that I'm not used to.Out of the box, its pretty well packed, and has everything you need except high end HDMI cables. Get the best that are at a reasonable price point, you will be happier. The unit supports 4 computers, and 2 monitors/tv's. The included instructions are amusing, but they get the point across.Once you have the USB cables plugged into your PC's and your video output (must be HDMI on the KVM end) plugged in, you have to plug in the KVM to your mouse and keyboard (use the 3 USB ports in a row) and then the HDMI outputs to your monitor(s). There is a physical hard switch on the back of the unit for power, as well as 2 push buttons, one on the unit and one on the remote console. The console connects using the USB-C to USB-C cable thats included with the kit.Changing is merely a matter of pressing the buttons on the console. A small blue/green led display gives you current status, as well as a series of lights on the front of the KVM. Its is supposed to "remember" the state of a particular PC video output, but with only 2 PC's and one monitor that feature is not going to have a lot of exercise with my setup.The unit itself is heavy for its size, and feels sturdy. Uses a wall wart power supply, and appears to be passively cooled. I would recommend placing in a well ventilated spot to allow it to stay cool.Works, can recommend.

I have 3 PCs that I switch between, a gaming system, finance system, and work system. I kept having to switch cables and go through a lot of hassles until I got a KVM switch, but that was only a 2 port device, so I still had to swap cables from time to time when I needed the unconnected PC.The 4 port KVM switch was the answer to my problems. I love this thing. I can now hook all 3 of my PCs together, and they can share the same monitors. The ability to connect 2 monitors is great, allowing you to extend your desktop. The unit is so flexible, that you can actually map the two monitor ports to different PCs.I also love the remote control deck which allows you to put a control panel away from the cables. It is straight forward to operate, just select which PC you want to go to which monitor. The buttons illuminate to tell you which PC is connected to which monitor. The mouse and keyboard are mapped to the last button that is pressed, so you can easily swap them between computers.There is a small display on the main unit and the remote control box which gives you information on the monitor resolution and USB mapping. There are also LEDs on the front of the main box which indicate which PC each monitor is connected to, as well as what PC the USB ports are mapped to. There are also headphone and optical audio outputs which can route the HDMI audio signal.I finally have a computer setup which allows me to use all my machines and swap between them effortlessly. I am amazed and impressed by how well this works and wish I would have gotten a 4 port switch much sooner. It even has room for expanding to another PC, so I may hook up my Linux sandbox machine to the setup. If you are frustrated which swapping cables to multiple PCs, this device is the answer. Unless you need some high resolution beyond 4K and 60Hz, this little device works magic.

The ROFAVEZCO EZCOO 4K 60hz HDMI KVM Switch is a pretty good switch. The main unit is heavy, weighing in at 1.38 pounds. The controller conversely is very light at 3.1 oz! Ridiculously, they decided to not include silicone feet on the controller or on the main unit to hold it in place on a desk. There were stickers which you could stick onto the bottom of the controller and the main unit which protrude a far distance from the surface. Instead, the same gloss piano black which is on the top is on the bottom so it tends to slide around!The gloss piano black also is a fingerprint magnet. I did not like how flat the buttons are to press. It can be hard to find and depress them since they are so flush with the surface and don’t have any real distinguishing texture to them. They also give a very hard, loud click feedback when pressed.They included four USB 3.0 cables with the device which is unusual currently to supply cables but they are very good cables with decent length to them. There is also a USB C cable which feeds from the main unit to the controller.The main unit is thin at 1.009 inches while being long at 8.5 inches, it is not very wide at 4.412 inches. The controller is 3.975 inches wide by 4.673 inches long by 1.01 inches tall.The ports of the main unit are well designated with 1 hdmi and usb 3.0 port separated for four PC’s. There were also three usb 3.0 ports, two HDMI out ports, SPDIF port and headphone jack out.The device included a power port which seemed to be ready to be converted to different charging standards but they only included the American outlet style.The switch worked well to maintain 4K at 60 hz on my dell monitor. Switching between PC’s was quick and easy. It did put out some heat.

This is a really solid KVM. It works well and syncs reliably. Almost all KVM these days don't include cables, but I feel that is okay since they no longer use proprietary dongles.

This is a fantastic KVM from EZCOOTECH. The separate controller which allows you to change the display resolution of each monitor on the fly is pretty awesome and definitely a game changer, it's the only KVM I've ever seen that has this amazing feature.The one and only thing about this that may limit its usefulness for the "gamer community" is it's limited to 4k@60hz. For most folks (read: non-gamers), this isn't really even a limitation. But if you intend to use this for gaming, know that higher refresh rates are not supported, such as 120/144 hz. So if you use high refresh rates, you may want to seek other solutions. But for the vast majority of folks, this is going to be one of the best KVM's you've seen.
