How to choose the best KVM switch

If you want to buy the best KVM switch available, and it is assumable that you do, you should take care of the following KVM switch characteristics:

Number of ports

As you may guess, the more ports there are, the more computers you can connect to the KVM switch. For that reason, make an assumption of how many computers you will simultaneously work with and make the purchase in accordance with that.


The last thing you need is to purchase a device and later discover it cannot work with your computer because of compatibility issues. Therefore, be sure that the desired device complies with this “small” requirement.

Video Output Type

Things are pretty straightforward considering KVM switches. If, for instance, your rigs have only the VGA video outputs, your only option is the KVM switch with that connection.

In other words, these two things must comply with each other. Therefore, don’t forget about this little detail before the final decision.

Reliable people don’t use the words “excellent” and “not the best quality control” to refer to the same product. “Avoid” is the only word for such products.
