3-Computer Dual-Monitor KVM

This WRIARICH 302DH switch lets one keyboard, mouse and four USB 3.0 peripherals control three computers across two displays. It accepts both HDMI and DisplayPort inputs from each host and provides two monitor outputs. A wired remote and front-panel buttons change the active system, while LED indicators show the current selection.

Ideal for Three-System, Two-Screen Setups

Suits professionals and enthusiasts who run three PCs or laptops and want a single keyboard, mouse and peripheral set spread across two monitors. The switch supports extended, mirrored and splicing display modes. Buyers with only one monitor, those needing to connect four or more computers, or anyone requiring a different video interface mix should consider other options.

4K 144 Hz Over DisplayPort

DisplayPort inputs deliver up to 4K at 144 Hz and 8K at 30 Hz, while HDMI inputs reach 4K at 120 Hz and 8K at 60 Hz. The USB 3.0 hub runs at 5 Gb/s through four ports for keyboards, mice, printers or storage. A 12 V power adapter, three USB 3.0 cables and the wired remote are included in the box.

Questions about this item

Which video cables must I already have to connect three computers to the 302DH?

You need three HDMI cables and three DisplayPort cables — one of each per computer — because each PC connects through both an HDMI and a DisplayPort input on the switch.

Will my existing 4K 60 Hz monitors work with the 302DH?

Yes, the switch is backward compatible and will run 4K at 60 Hz on either HDMI or DisplayPort inputs without any extra setup.

How do I confirm the 302DH is routing video and USB to the correct computer after I press the wired remote?

The front-panel LED indicators light up to show which of the three computers is currently active, giving immediate visual confirmation.
