For those who aren’t familiar with KVM, it’s basically an acronym that stands for keyboard, video, and mouse. A KVM switch is a device which allows you to control more computers or servers using only a single keyboard, video monitor, and mouse by employing a special dial or buttons on the switch. You can imagine the KVM switch as a ‘parent’ device which takes over the computer CPUs and servers that represent the ‘children’ devices.

There are many situations in which a KVM switch can come in handy. It depends on individual needs, but there are some great uses for both the personal and the professional sectors. A KVM switch can offer lots of benefits to those who have jobs that need the constant toggling between different operating systems. On a simple search for this product online you can discover a great variety of products, some of them really cheap, others more expensive. If you wish to figure out which one’s best for you, analyzing a few aspects would be a solid starting point.
1. Power supply
Some KVM switches get their power through the connected computers, but others have an internal source of energy. The internally powered models are usually more reliable as they deliver a consistent level of performance. This is mostly because they don’t have to rely on the capabilities of the host computer.
When you’re shopping for a KVM switch, is essential to watch out for compatibility with your operating system. Some models run well with both Mac and Windows systems but you can occasionally find others that could only work with either Mac or Windows.
3. Port Capacity
The more basic models can simply switch between two different computers just by using one monitor, one mouse, and a single keyboard. There are also some more advanced units with larger port capacities which can toggle between numerous computers. It’s important to analyze your particular needs to figure out which model would be better.
There are probably other relevant features to consider, but these are the main ones to have in mind. Armed with this knowledge, let’s start looking at what’s in store for high-quality KVM switches. Take a look at the following list which contains a diverse range of products that should be suited for multiple budgets and less or more demanding needs.

There are many people unwilling to invest too much in a very complicated KVM setup. If you’re one of them, you should check out the Rosewill RKV-2UC, a KVM switch that delivers some basic functionality without any major flaws. The price is probably one of its standout features as it’s quite low.
A great ability of this switch is the DVI functionality. From one DVI console, you can take control of two USB computers. The switching is done through a USB mouse, hotkeys, and via a remote port selector. The KVM switch is capable of USB 2.0 peripheral sharing but a USB hub is required for the USB mouse port.
I’ve mentioned the remote port selector and this is actually a very nice feature of this switch. What this does is basically enabling you to control port switching from the desktop even if the switch itself is located somewhere else, stored in a more convenient place.
Besides allowing for lots of hotkeys to make the switch to another computer, this model also supports a mouse port-switching function. A double-click on your USB mouse’ scroll wheel is enough to make the switch.
A great enhancement comes with the addition of the Video DynaSync technology that should prevent any resolution problems with the displays that can occur when switching. This feature also helps with boot-up display issues. The final function worth mentioning is the Power on detection ability. In case one of the computers is turned off, the switch will recognize it and automatically move over to the next unit that’s powered-on and switch to it.
Despite offering a fairly simplistic approach to KVM switching, the Rosewill RKV-2UC is worth considering if you want to stick to the essential features. The only weak aspect is the quality of the switching buttons. A bit too much plastic here leaves off a cheap impression. Still, you get what you pay for and considering the overall functionality and the quick switching, this is recommended.
