What Is KVM, And How Does It Work?

KVM stands for ”Keyboard, Video, and Mouse”.

There are various types of KVM switches are available in the market. Some of them are –

  • Semi DDM
  • Emulated USB

There are some remote KVM switches that are also available in the market. Although these are not very common, they are still used in big data centers and home servers. 

KVMs are very effective devices, they tend to have latency issues very often. You might find some high-quality KVM switches that do not have this issue, but chances are they’re costly.

Therefore, KVM switches are not ideal for personal use, especially when there are other readily available ways of connecting two computers to one monitor.

How To Connect Two Computers To One Monitor (Without KVM)

Now, let us see in detail how you can connect two computers to one monitor without KVM switches. 

1. Use Monitors Ports

If you check carefully, you will find multiple IO ports at the back of your monitor. These could be HDMI, DVI-D, or DisplayPort.

If you can not understand the difference between the ports, please check the monitor’s instruction manual. A Google search will help you as well.

Depending on your monitor and its model, it might have different ports. For example, some monitors have two HDMI ports and a VGA port. 

Use Monitors Ports

Once you have figured out the ports and their type on your monitor, you need to check the port on your computers.

GPUs these days come with multiple ports, so more likely than not, you have many connectivity options on your computer. It is a possibility again that you find two ports of the same connection. 

So, if you have two computers with an HDMI port and a DVI-D port, you require your monitor two have one HDMI and one DVI-D port. You can then connect the computers to the matching ports. 

If you have two HDMI ports on the back of your monitor, you will have to use the HDMI ports of both of your computers to connect to the monitor.

Just keep in mind that if your monitor comes with higher refresh rates, then connect it with the right cables. Otherwise, you won’t able to achieve the maximum refresh rates.

It would be best if you made sure that the cables you use are not damaged. It would also be better to clean the ports and get rid of any dust and dirt before connecting them. 

To switch between the computers on your monitor, use the ”input toggle/source” button. You will find this button on the OSD menu of your monitor.

Please check the user manual or visit the manufacturer’s website if you cannot find it on your model.
