There was once a time when livestream gamers on platforms like Twitch usually had two different settings for playing the game and another for streaming.
Usually this meant having two sets of keyboards, mice and monitors. Users would have to physically switch from playing a game on one computer to another to control live streaming software such as OBS software.
That changed with the rise of KVM, which stands for ‘Keyboard, Video, Mouse’. Interestingly enough, the technology was initially developed for large data centers that may have multiple servers and computers on a server rack.
Through software or hardware, KVM switch capabilities allow users to control or switch multiple PCs from a single keyboard, monitor and mouse. Instead of using multiple inputs and monitors, only one is needed.
Most importantly, it’s a great way to save installation space and money on additional input devices. In addition to streaming, this is also a great way to potentially use an individual’s PC with a work computer.

In recent years there has been a rise in gaming monitors with integrated KVM switches. For many, this starts with displays like the Gigabyte M27F.
Medium to high level displays ranging from the MSI MPG271QR Unpleasant BenQ Mobiuz EX321UX besides others of our favorite gaming monitors have now standardized the options.
That’s perfect for streamers who want to free up system resources on their gaming desktop for better visual quality or frame rate, while allowing another device to handle the actual livestream.
One more tool needed for this is a capture card to send video data from the gaming desktop to the secondary device used to produce the stream.
By the way, KVM works on game consoles such as Xbox Series X|S or PS5 also depends on the monitor. This means console gamers working from home can get a few games Call of Duty: Black Ops6 or Fortnite during breaks without switching inputs.
It’s also great for console gamers who want to stream as well. Please understand that not all games offer keyboard and mouse support on consoles.
While there are some minor differences between the way KVM works with monitors, there are some common threads that potential users should be aware of. That said, we are here to help readers interested in KVM understand its uses.
2. How does it work?

Most monitors with KVM switches have a USB-B port that allows upstream to one computer. This allows the other downstream USB-A ports on the monitor to be used for mouse and keyboard.
If the other device is a more modern laptop such as a Macbook, users simply need to connect one USB-C port to the one on the monitor and that’s it.
Another desktop may require a second USB-B port on the monitor, in addition to a video output port to the monitor, such as HDMI or DisplayPort.
For game streaming, it is best to use DisplayPort for the main gaming desktop due to its frame rate performance capabilities as mentioned earlier, and the other one available can be used for the high-quality stream.
3. Who else can use KVM?

Although it has become the most popular in terms of usage, gaming is not the only use of KVM for streaming. Music producers and artists have started using KVM as a way to hold satellite sessions or showcase their talents via Twitch as well.
Speaking of audio, it may be best to use the monitor’s 3.5mm headphone jack for whatever you’re using as your main connection, if possible. For good audio quality during the stream, most professionals use a quality microphone for the other device.
After that’s done, this is where things can get tricky depending on the type of monitor you have. Some monitors may have a hotkey or a KVM button or may use some menu prompts. It really is that simple.
We recommend that you refer to the manufacturer’s manual depending on the actual monitor.
Why KVM is a must-have for many users
The KVM switch in gaming monitors has revolutionized efficiency, versatility and space management for professionals and gamers alike. The ability to connect multiple devices with minimal effort underlines its utility appeal.
The technology serves as another evolutionary step for the devices, including everything from the introduction of DisplayPort and curved displays to even the introduction of a 120Hz refresh rate.
