Dual-Monitor KVM Switch

The v AV Access 4KSW21-DM lets one keyboard, one mouse and two HDMI monitors control two computers. It supports extended or mirrored desktop modes and switches by front-panel button or keyboard hotkey. A built-in USB 3.0 hub shares up to three peripherals at 5 Gbps and audio or microphone paths follow the active PC. No driver installation is required for Windows, macOS or Linux.

Office, gaming and learning setups

The unit suits users who need two computers driving two screens at up to 4K 60 Hz, 2560 x 1440 at 144 Hz or 1080p at 240 Hz. It is not for buyers who require more than two computer ports, more than two monitor ports, or native dual-extended-mode on macOS — that platform is limited to mirror mode only.

4096 x 2160 maximum resolution

The single specification that decides fit is the 4096 x 2160 video ceiling with the listed refresh-rate tiers. If your workflow demands higher resolution, additional video inputs or Mac extended-desktop support, this model will not meet the requirement.
