How to use one keyboard and mouse for two computers?

1. How to use one keyboard and mouse for two computers?

How can I use one keyboard and mouse on two computers at work? Often requiring multiple switches between the two computers for configuration or file transfers. In this process, every computer will inevitably need to operate a keyboard and mouse, so usually this means that you need to use two sets of keyboard and mouse.

If you don’t have a suitable workspace, it can become a hassle, either with two sets of keyboards and mice cramming your narrow desktop, or one set of keyboards and mice plugging back and forth.

Is there any solution? Of course there is.There are usually 3 methods as follows

    1. Use a mouse that can control multiple devices
    2. Use software like Synergy or Mouse Without Borders
    3. Use KVM switch or USB to copy the cable

1. Use a mouse and keyboard that can control multiple devices

The first solution is a wireless keyboard and mouse with switchable connected devices. Many mainstream wireless keyboards and mice now support manual switching of multiple devices, such as the Cool Burn series of keyboards and mice. This set of keyboard and mouse has two connection methods, USB wired and Bluetooth wireless connection. Through Bluetooth wireless connection, these keyboards and mice can be connected to 3 devices at the same time, whether it is desktop PC or laptop, ipad, etc. On the keyboard, you can switch freely among the 3 connected devices through the 3 keys “Fn” + “Q” “W” E”.

The advantage of this method is that it is very simple, you only need to connect the 2 or 3 devices you need to switch, and there is no need to install or purchase any software and hardware, which is the most time-saving and labor-saving method. The disadvantage is that if you connect 3 devices at the same time, you may not be able to remember which device corresponds to which switch button, but as long as you correspond to the sequence of buttons in the order in which the computer is placed, it can be solved very well.

If your keyboard and mouse are just ordinary keyboard and mouse, and do not support switching connected devices by pressing keys, is there any other way to control two computers with one keyboard and mouse? Of course, it can also be done by some software or hardware.

2.  Use software like Synergy or Mouse Without Borders

1.First download, install it on two computers separately, and open it. The interface is as follows:

2.Click NO on the computer connected to the mouse and keyboard, and click YES on the controlled computer.

3.Then, the client that clicks NO will generate a string of passwords and display the device name of the computer at the same time. Correspondingly fill in the computer that clicked YES, and click LINK to connect.

4.After the connection is successful, you can use this keyboard and mouse to control two computers.

With Mouse without Borders, you can not only share the keyboard and mouse, but also share the clipboard, drag and drop files across devices.

After downloading, installing and running Synergy on your computer, when the mouse moves to the edge of the computer, it slides into the next computer desktop, enabling seamless switching between computer screens.

ShareMouse adopts a free + paid usage model. The free version only supports the connection of 2 computers and has certain functional limitations. If you want to connect more computers, or use more features, such as copying the clipboard, drag-and-drop copy files to another set of computers, you need to enable paid features.
