This wiki has been updated 4 times since it was first published in January of 2019. Keyboard-video-mouse (KVM) switches are commonly used by network administrators, as well as a host of other tech professionals, for unified control over multiple computer systems using only one set of input devices. They're also quite helpful for home users who utilize separate PCs for various different tasks. Whether you're at work or play, the right 4K model can streamline your experience.

Editor's Notes

February 05, 2019:

With so many advances in modern technology and manufacturing, complex and high-powered computer systems are more common in both the home and business than ever before. But when moving from one system to the next, nobody wants to climb underneath a desk and start unplugging and replacing various cables. Enter the KVM switch, which has been a staple of network admins for a while, and is capable of making many power users' lives easy, as well. When it comes to 4K video, there are a few competing standards, and DVI, HDMI, and DisplayPort are the main ones currently used. Take note, however, of the versions that you're looking at. A single DVI, HDMI 1.4, or DisplayPort 1.1 connection is limited to UHD resolution at only 30 hertz, so if the most fluid motion is important to your work or play, you'll need to get a switch that utilizes HDMI 2.0, or DisplayPort 1.2 or later. The TESmart A1U is one such device, and at such a low price, it's hard to beat, if you only need to move between two PCs. The relatively expensive StarTech is a DisplayPort unit that also supports full 60-hertz refresh rates, but again, only high-budget outfits will find it terribly useful. The TESmart HDMI 2.0 is a 4-way option that supports HDMI 2.0, and it's remarkably affordable, considering its capabilities. Their RS232 marks a move up the ladder, and is designed for businesses that need a focus on security, with a wide array of physical connections that offer ample systems management opportunity. In between those is the E-SDS, which allows a maximum of 8 connections, and is moderately priced for a small enterprise device. IOGear offers a wide range of useful options, and their GCS1940 series offers enough bandwidth to drive multiple UHD monitors at once, while the GCS1440 line is also effective, but not able to utilize a 60-hertz refresh rate — plus, you'll likely need to get some adapters along with it.
