Triple-monitor KVM for three PCs

The WRIARICH KC-303DH lets three computers share three displays and four USB 3.0 ports. Each system connects through one HDMI and two DisplayPort inputs. A wired remote and front-panel buttons both switch the active computer. Driver-free operation keeps setup simple for home offices and multi-system workstations.

Video bandwidth and cable requirements

The switch passes up to 8K at 60 Hz or 4K at 144 Hz across all three outputs. Achieving these rates requires HDMI 2.1 and DisplayPort 1.4 cables; longer runs may reduce the maximum supported resolution. USB 3.0 peripheral ports deliver up to 5 Gbps, while USB 2.0 devices fall back to 480 Mbps.

Check your graphics outputs before ordering

Each computer must provide three native video outputs — one HDMI and two DisplayPort — to drive the triple-monitor layout. If a system only has two outputs, the third screen will stay dark. All three USB upstream cables must be connected for keyboard, mouse and other peripherals to be recognised on every PC.

Questions about this item

Should I choose the HDMI plus two DisplayPort version or a different connector mix for three monitors?

This KC-303DH model provides exactly one HDMI and two DisplayPort inputs per computer, so the connector mix is fixed and matches the three-monitor layout.

What does the 8K@60Hz and 4K@144Hz rating mean when I connect three displays?

Each video channel can carry up to 8K at 60 Hz or 4K at 144 Hz, provided the source, cables and monitors all support those modes simultaneously.

Which video standard does the HDMI 2.1 and DisplayPort 1.4 interface cap in practice?

HDMI 2.1 and DisplayPort 1.4 set the bandwidth ceiling that allows 8K@60Hz or 4K@144Hz per port when compatible cables are used.
