Best KVM Connector Buying Guide – What to Look for in a USB KVM Switch, KVM Switch HDMI, DIV KVM or VGA Switch

Multitasking, a blessing or curse? Well, we like to think the answer to that question is based on how you approach the issue of multitasking. Picture this instance: for some reason, you have to use more than one computer at a time, probably for work, but then you discover you’re going to need more space than you have to accommodate the new entrants. Then the struggle begins, you relocate the former occupants of your desk space and go the extra mile of squeezing in a rack or table; you then proceed to arrange your computers, keyboards, mice, speakers and all the other accessories in a manner that will maximize the little space.

When you’re done, you stand back and inspect your work. Shaking your head at the result, you tell yourself you’ll make do but when you find yourself stretching and bending at unnatural angles to reach the audio/mic port behind Computer 2 or to reconnect the USB-wired mouse that you accidentally disconnected while trying to reposition the screen so you can type an urgent email on Computer 1. You end up tense and frustrated. This picture definitely doesn’t look like a blessing!

Now, instead of going through all these steps, you decided to take advantage of technology’s benevolence and get yourself a clever device that will have you tossing out the idea of getting extra keyboards, mice, monitors or any other such hardware and going instead for a more streamlined and unified control option that will allow you to control all your computers from a single keyboard, mouse and monitor without moving from your seat, thereby increasing your overall productivity and keeping you from insanity – now, that’s definitely a blessing.

What’s this device to which we allude, you may ask?

It’s none other than a KVM switch. It’s a computer solution that does all that has been described above and a little more. With it, whether you’re working from your home office desk or in a commercial server room, you get to achieve more in less time and with fewer dollars. KVM switches come in a variety of designs; while some of them connect you to 2 computers at once, some others can do so for 16 computers and more. Many of them can be daisy-chained with USB hubs to connect dozens of computers. We know that you’re on a search for the best KVM switch and we hope our guide will make your search a short but rewarding one.

Introduction to KVM

What is a KVM switch? | Courtesy of TechTrainerNJ

The price of a KVM switch is basically determined by its features. An 8-port switch will cost more than a 2-port switch but not as much as one with 16 ports. Here is another one; a 2-port switch that allows for extra devices, like printers, to be connected and shared between the computers will sell for more than another 2-port switch that lacks such a feature; the more basic its functionality, the less it will cost. You’ll find KVM switches selling for $15 to $1200 and more. We did find cheap KVM switches but we weren’t pleased with the quality, so we passed and you should too.


There are certain things you’ve got to have at the back of mind as you shop for a KVM switch. You have to know how many computers you intend to connect. You also have to specify whether you want them connected for audio, video, text or all three? Then there’s the issue of operating systems – whichever switch you choose needs to be compatible with your computers. Other important features to look out for include:

  • Video display output
  • Number of ports
  • Maximum video resolution
  • Audio capability
  • Accessories
Construction and Design

KVM switches are designed to be specific to operating systems, video display platforms and, on some occasions, hardware. In the case of operating systems, many of these switches have “multi-platform OS” written on their packages or features page but you’ll have to pay more attention as they usually mean about 2 to 4 operating systems are supported. The most common operating systems supported by a majority of these switches are Windows, Mac, Linux, Sun, and Ubuntu. Ensure you verify the operating system and the version supported by a KVM switch before paying for it.

You’ll find stuff like VGA, DVI, HDMI, DisplayPort in KVM switch’s name. These describe the type of video display cable the unit will work with. VGA has been around the longest by far, but it’s still very much in active duty and can be found in a lot of computer monitors today. DVI is available in 3 types: DVI-I (integrated), DVI-D (digital) and DVI-A (analogue). Switches with this video display will specify which of the types is supported; we did find a lot of DVI-Is though. HDMI and DisplayPort are the latest in video display technology; they’ll give you more colors and maximum resolutions. Remember to match this to the available outputs on your computers as well as the input on your monitor.

How to Set Up a KVM Switch

Performance and Ease of Use

How many computers do you want to connect? How many peripheral devices, apart from the keyboard and mouse that will form a part of the console, do want to add? Knowing the answer to these questions will save you from spending more than you need to. The least number of computers that can be connected to a KVM switch is 2 and it can go as high as 32. In a commercial or industrial set-up with more than 100 computers, the KVMs are daisy-chained or cascaded to accommodate more PCs. If you want to add a printer or any other peripherals to the network, it’s best you find a switch with extra ports for that. Lest we forget, the ports are usually any version of USB interface.

Ensure you end up with a switch that has a resolution compatible with your monitors otherwise you’re going to have error messages informing you of the mismatch when you try to connect. A KVM switch’s resolution is generally dependent on the type of video display it comes with and so a switch won’t have a higher resolution or lower resolution than its display cable. Make sure that it also has audio capabilities as well – check for audio ports or jacks to confirm this.

Check out seemingly little things like cable length as it can make or break the rewards of getting a switch. Consider the distance between the computers and devices you’re connecting then find a switch with cables that will conveniently cover that distance.

KVM Switch FAQs

What is a KVM switch?
A KVM switch is a device that you can use to control multiple computers from one set of mice, monitors, and keyboards. One can use it to switch between multiple PCs or servers easily and quickly. Therefore, you don’t have to move from one computer to another physically. To learn more, check out our KVW switch review.
How does a KVM switch work?
A KVM switch works by connecting computers using KVM cable or Cat5 cables. That creates a network of computers, which makes it possible to display the contents of each one of them on one monitor.
How to use a KVM switch
To use a KVM switch, you should connect the computers using KVM or Cat5 cables. Once that’s done, you can connect the mouse, display, and keyboard console, in case the switch doesn’t have one. With that, you can use one keyboard button, hotkeys, or onscreen controls to switch between multiple computers.
