Four-computer dual-monitor switch

This KVM lets four PCs or laptops share one keyboard, one mouse and two monitors. Each source must provide two video outputs and support extended desktop mode. The unit handles dual HDMI natively or HDMI plus VGA, DVI or DisplayPort via adapters that are not included.

4K 60 Hz 4:4:4 headroom

Video reaches 4K at 60 Hz with 4:4:4 chroma and separate audio in and out. Auto EDID keeps handshakes stable across all four ports. USB 2.0 peripheral ports add printer or scanner sharing, but bandwidth stops at 2.0 speeds so high-throughput devices will bottleneck.

Five switching methods included

Hot-key combos, mouse-click switching, front-panel buttons, auto-scan at 8 to 999 second intervals and RS232 serial commands all change the active system without drivers. The box supplies every video and USB cable plus a 5 V 1 A power adapter, so the switch works immediately after cabling.

Questions about this item

Will this KVM switch let me keep using my older laptops that only have VGA or DVI outputs alongside newer HDMI machines?

Yes, the switch accepts dual HDMI or HDMI plus VGA, DVI or DisplayPort sources, but you must supply your own adapters for the non-HDMI ports.

How can I confirm the switch is passing 4K 60 Hz 4:4:4 video and separate audio to both monitors after I connect everything?

Check each monitor’s on-screen display or OS display settings to verify 4K at 60 Hz with 4:4:4 chroma, and ensure audio plays through the switch’s dedicated audio output.

Which cables and accessories ship with the unit, and what do I need to buy separately for four computers with mixed video outputs?

The box includes all required HDMI cables, a USB 2.0 hub cable, a DC 5V/1A power adapter and the RS232 control cable; you must purchase any VGA, DVI or DisplayPort adapters separately.
