Short answer: if you want one keyboard and mouse to control 2, 4, or up to 8 computers without installing sharing software or keeping every computer on the same LAN, WBT2-V4 is the WSCOME hardware switch to look at.
4 computers, 1 keyboard and mouse: WBT2-V4 is a WSCOME hardware option for using one keyboard and mouse with 4 computers, without installing keyboard-sharing software or putting every computer on the same LAN. It switches keyboard and mouse input only; monitor/video switching stays separate.
This page is for users who already have their monitors arranged and only need to switch keyboard and mouse control between computers. WBT2-V4 is not a video KVM switch. It does not switch HDMI, DisplayPort, or monitor signals.
When this setup makes sense
- You have 2 computers on one desk and want one keyboard and mouse.
- You have 4 computers for work, testing, mini PCs, or different operating systems.
- You want a setup that can scale up to 8 computers with the same keyboard and mouse.
- You cannot install software such as Mouse Without Borders, Synergy, or Barrier on every computer.
- Your computers are on different networks, isolated networks, or no network at all.
Why use hardware instead of software sharing?
Software keyboard and mouse sharing can be useful, but it depends on software installation, network access, and system permissions. That can be a problem on work computers, test machines, offline computers, or machines that are managed by different people.
WBT2-V4 is different because it is a hardware keyboard and mouse switch. Each computer receives keyboard and mouse input through a paired WSCOME receiver or Bluetooth connection, depending on your setup. The computers do not need to be on the same local network.
2 computers, 4 computers, or 8 computers
| Setup | Typical need | WSCOME fit |
|---|---|---|
| 2 computers | One work computer and one personal computer, or one desktop and one laptop | Use one keyboard and mouse without a software-sharing tool |
| 4 computers | Workstation plus test machines, mini PCs, or mixed operating systems | Switch keyboard and mouse control without putting all computers on the same LAN |
| Up to 8 computers | Compact lab, repair bench, multi-PC desk, or small server maintenance setup | Use WBT2-V4 as a dedicated keyboard and mouse switch instead of a video KVM |
