Three-system control

The WRIARICH 303DH KVM switch lets three computers share three monitors and four USB 3.0 peripherals from one keyboard and mouse set. It targets professionals and enthusiasts who run multiple workstations side by side and want instant switching without unplugging cables.

Upgrade from manual cable swaps

The jump is worth it when you move between three PCs daily and need both extended and mirrored display modes across two DisplayPort and one HDMI output. Each computer must provide its own video outputs and connect with a USB cable, otherwise the shared peripherals will not function.

Cable and bandwidth limits

HDMI 2.1 reaches 8K at 60 Hz and 4K at 120 Hz, while DisplayPort 1.4 reaches 8K at 30 Hz and 4K at 144 Hz. Cables longer than 1.5 metres risk black screens or flicker, and every connected PC must support triple-display output for the extended mode to work.

Questions about this item

What video cables do I need to reach 8K@60 Hz on the HDMI port and 4K@144 Hz on the DisplayPorts?

Use HDMI 2.1 cables for the HDMI port and DP 1.4 cables for the DisplayPorts; keep each cable shorter than 1.5 metres (59 inches) to avoid black screens or flicker.

How do I switch computers with the wired remote, and what step is often missed?

Press the remote button to cycle through the three PCs; the step users miss is connecting a USB 3.0 cable from each computer to the switch, otherwise the keyboard and mouse will not follow the video.

When should I replace the video cables to keep 4K@144 Hz stable?

Replace any HDMI or DisplayPort cable that shows intermittent signal loss, flicker, or failure to negotiate 4K@144 Hz; cables longer than 1.5 metres degrade first and should be swapped for certified 1.4-metre or shorter leads.
