Two-PC Dual-Monitor KVM Switch

The TRENDnet TB-SW221 lets two computers share two HDMI displays and four USB 3.0 peripherals. Switching is handled by push buttons on the unit. It supports video resolutions up to 8K at 60 Hz and 4K at 120 Hz, plus 1080p and lower modes. The box includes built-in cables for a plug-and-play setup.

Suits Two-System Desk Setups

Ideal for users who need to toggle a keyboard, mouse, printer and external drives between a pair of Windows, Mac or Linux machines driving twin monitors. Not suited for single-monitor workflows, for setups requiring more than two video inputs per computer, or for environments that demand switching via hotkeys or IR remote instead of the front-panel buttons.

Video and USB Throughput Headroom

Each display channel handles 8K at 60 Hz or 4K at 120 Hz, so modern high-refresh panels run at native capability. The four USB 3.0 ports deliver 5 Gbps bandwidth for fast external storage and peripherals. The switch tops out at two computer ports and two monitor ports; adding a third system or a third display would require a different unit.

Questions about this item

What type of video outputs must each computer provide to drive both monitors through this KVM?

Each computer needs two HDMI outputs to connect to the switch’s four HDMI input ports.

Will my existing USB 2.0 keyboard and mouse work with the four USB 3.0 ports on this switch?

Yes, the USB 3.0 ports are backward compatible with USB 2.0 peripherals such as keyboards and mice.

How can I confirm the switch is passing the highest supported resolution to both displays?

Verify in your OS display settings that each monitor shows 8K at 60 Hz or 4K at 120 Hz, depending on your source.
