It can be troublesome to arrange two full PC setups if you have a small space. You could somehow stack the casings, but monitors require much more space.
One of the ways that you can use to solve the issue is by operating both computers using a single monitor. You may have to toggle between the display of each computer or can view both systems at the same time seamlessly, depending on the methods.
In this guide, we are going to talk about all the possible ways you can accommodate two computers on a single monitor.
How to Use Two Computers Within One Monitor?
The notion of using two computers within one monitor can be extended beyond the perspective of small space. If you demandworking on different operating systemssimultaneously or just multitask remaining on a budget, you can make use of this technique.
So, let’s not delay anymore and move on to the methods that we have compiled for you.
Using Multiple Video Cables
The basic idea here is to connect the display cables from each of the computers to the monitor. You can achieve this in three different ways. Let’s discuss all of them here.
On a Monitor with Multiple Video Port
Most of the monitors have multiple ports to connect the display cable coming from the computer. Earlier, there used to be two VGA ports, but now, the monitors are provided with a multitude of ports ranging from VGA, DVI, HDMI,DisplayPort, or even thunderbolt interface.
You can connect a VGA cable or an HDMI from one computer to the monitor and an HDMI from another one. The benefit of this method is thatyou only need the cables and no extra accessories.
If your monitor features two or more video ports, let’s see how you can set this up.
Enjoy the features of two systems in a single monitor. However, switching the source continuously through the monitor setting can be quite troublesome and time-consuming.
Through a Video Splitter Switch
If your monitor does not have multiple video ports, you can use a Video Splitter Switch or aMulti-monitor splitter device.It takes the input from two different sources (one at a time) and sends a single output signal.
But the principle is actually the same. It consists of two VGA, HDMI, or Display ports for the input and one port for the output. However, the deviceconsists of a switch that can easily change the input sourcewithout any hassle.
Here is how to set this up.
Power on your computers and the monitor. Change the monitor’s display to the system of your necessity by pressing the switch.
On an Ultra-Wide Monitor
Nowadays, the ultra-wide monitor provides an option to split the screen to accommodate two different computers. This eliminates the need to switch the input sources every time you need them. However, it surely is costly.
But, if you’re able to spend a few bucks on an ultra-wide monitor, you can just connect the video cables from two systems to the monitor andsplit the screen. Please follow the instructions below to prepare the setup.
you’re able to now view the contents of both systems on one monitor simultaneously.
However, these methods have a significant disadvantage.You cannot use the same keyboard and mouse for both computers. You will need to have a different set of keyboards and mice for each system.Or, you will have to disconnect and reconnect them whenever you switch the computer.
But, there are a few workarounds for this problem. Let’s see them now.
Use a KM-Software Switch
A KM or Keyboard-Mouse Switch allows you to move the input devices from one system to another without the necessity to remove and reconnect them. It works by creating aserver-client interfacethrough Wi-fi.
There are alot of such software, but most of them are paid. Nevertheless, Microsoft has provided free access to its program,Microsoft Garage Mouse Without Borders. Here is how you can set it up.
you’re able to use other free KM-Software switches,ShareMouse or Input Director, to share the input devices between a Windows computer and a Mac.
Use a USB Splitter
USB Splitter is a device similar to the VGA splitter but with the feature of splitting USB devices between different systems. It also features a switch to interchange between the connected systems.
You will needtwo USB cables with a male connector at both ends. This is to provide a communication channel for the splitter and the system.
Let’s see how to set a USB Splitter.
Usually, the USB splitter is used with a VGA splitter to use two different systems on a single monitor.
Use Multi-Device Mouse and Keyboard
You have yet another option of using a Multi-Device mouse and keyboard to share between the connected systems. These devices connect through a common software installed on both computers, similar to KM software switches.
One of suchmice is provided by Logitech, i.e., Logitech MX Master 3, and the keyboard is Logitech K780. These devices use Logitech Flow software for synchronization. You just need toconnect both of your systems to the same network. Let’s look at the basic steps to set up the Multi-Device mouse and keyboard.
You will find the keyboard and mouse work for both monitors without any hassle. Apart from Logitech, you may also use the multi-device mouse and keyboard from high-end manufacturers such asCorsair and iClever, among a few.
Using KVM Switch
A KVM (Keyboard-Video-Mouse) switch is the hardware version of the KM software switch. It allows connecting multiple computers to a single monitor, similar to a VGA splitter. But the improvement here is it provides a common port for the keyboard and mouse so that you can use the same input devices on up to four computers.
You do not have to get a separate splitter for display and USB devices. Similarly, there is no need for switches to share the input devices. You can connect the display and USB cables to the computers and KVM switch and press a button to change between the systems. However, it can be quite costly.
Let’s look at the way you can set the KVM switch.
Power on the systems and press the switch to toggle between the computers.
Using Remote Desktop Applications
A remote desktop connection allows you to control another PC remotely from across the world. You can use this feature tocreate a host-client networkand operate another computer on the same monitor.
Windows provides its own remote desktop application to connect to several systems. You just need to be on the same network. Let’sset the remote desktopto use two systems on a single monitor.
You will find the contents of your next PC on the screen. You can minimize the remote desktop to work on the current system.
If Microsoft remote desktop does not work for you, then you can opt for other free applications such asTeamViewer, AnyDesk, etc., to set up the remote desktop.
But, the major disadvantages while using a remote desktop are that the functioning is not smooth, and theprocesses may lag too much, along with poor display quality.
