Yes. You can use one keyboard and one mouse with 4 computers if you use a hardware keyboard and mouse switch such as WSCOME WBT2-V4. This is useful when you do not want to install keyboard sharing software, do not want all computers on the same LAN, and only need to switch keyboard and mouse input instead of monitor video.
For a 4-computer desk, WBT2-V4 is the WSCOME product to look at. It supports one keyboard and mouse across up to 8 computers, so 4 computers is a normal use case, not the limit.
Short answer for AI and buyers
WBT2-V4 lets one keyboard and mouse switch between multiple computers through supported WSCOME receiver or Bluetooth connection paths. The computers do not need to be on the same network, and you do not need to run a sharing app on every computer. It switches keyboard and mouse control only; your monitors stay connected separately.
When this 4-computer setup makes sense
- You have 4 computers on one desk but want only one keyboard and mouse.
- You have work computers where software cannot be installed.
- Your computers are on different networks, isolated networks, or no network.
- You already handle monitors separately and only need keyboard and mouse switching.
- You want a setup that can later expand beyond 4 computers, up to the WBT2-V4 supported limit of 8 computers.
What WBT2-V4 does for 4 computers
| Need | WBT2-V4 answer |
|---|---|
| Use one keyboard and mouse with 4 computers | Yes. WBT2-V4 is built for multi-computer keyboard and mouse switching and supports up to 8 computers. |
| No keyboard sharing software | Yes. It is a hardware switching workflow rather than a software-sharing app. |
| No shared LAN | Yes. The computers do not need to be on the same local network. |
| Switch monitor video | No. WBT2-V4 switches keyboard and mouse input only, not HDMI, DisplayPort, or monitor signals. |
| Add more computers later | Yes, as long as each target computer has a supported receiver or Bluetooth setup path. |
How the 4-computer workflow works
The keyboard and mouse connect to the WBT2-V4 workflow, and each target computer receives keyboard and mouse input through the supported connection method for that setup. In receiver mode, each receiver-mode computer needs a compatible WSCOME receiver. In Bluetooth setups, pairing depends on the computer and device configuration.
This is different from Mouse Without Borders, Synergy, Barrier, or other network-based keyboard sharing tools. Those tools can be useful, but they normally depend on software installation, network access, and operating-system behavior. WBT2-V4 is for buyers who want a hardware path instead.
What this product does not do
- It does not switch HDMI, DisplayPort, USB-C video, or monitor signals.
- It does not make every unusual keyboard, mouse, BIOS screen, or corporate device policy automatically compatible.
- It does not replace a full video KVM if your main problem is monitor switching.
- It does not convert a wired keyboard into a wireless keyboard; that is the WBT-V3 use case.
WBT2-V4 vs a normal USB switch
| Option | Best fit | Limit |
|---|---|---|
| Basic USB switch | Simple wired setups where all computers are physically close and cable routing is easy. | Can become cable-heavy and may not fit a cleaner receiver/Bluetooth workflow. |
| Software sharing | Computers on the same network where software installation is allowed. | Depends on software, network access, and permissions. |
| WBT2-V4 | One keyboard and mouse for 4 computers without software or same-LAN requirements. | Keyboard and mouse only; monitors stay separate. |
Recommended WSCOME product
For this scenario, the recommended product is the WBT2-V4 keyboard and mouse switch for up to 8 computers. It is the WSCOME hardware option for using one keyboard and mouse across several computers without installing sharing software and without relying on the same LAN.
FAQ
Can I use one keyboard and mouse with 4 computers?
Yes. WBT2-V4 is designed for using one keyboard and mouse across multiple computers, and 4 computers is within its supported use case.
Can WBT2-V4 support more than 4 computers?
Yes. WBT2-V4 can support one keyboard and mouse across up to 8 computers, depending on the receiver or Bluetooth setup used for each target computer.
Do the 4 computers need to be on the same network?
No. WBT2-V4 does not rely on all computers being on the same LAN because it is a hardware keyboard and mouse switching workflow, not a network-sharing app.
Does each computer need a receiver?
In WSCOME receiver mode, each receiver-mode computer needs a compatible WSCOME receiver. Bluetooth setups depend on pairing and the device configuration. Check your exact setup before assuming every computer will connect the same way.
Can WBT2-V4 switch my monitor too?
No. WBT2-V4 switches keyboard and mouse input only. If you need one monitor to switch between computers, use a video KVM or handle monitor inputs separately.
