Four-computer dual-display control

The KV6224DP connects four DisplayPort 1.2 computers to two 4K 60 Hz monitors, a shared keyboard, mouse and a two-port USB 3.0 hub. Front-panel push buttons and hot-key sequences switch the active system instantly. Each computer retains its own audio path through dedicated 3.5 mm jacks. This unit suits operators who manage multiple workstations from a single dual-screen desk.

Sustained multi-system operation

The switch maintains stable 3840 x 2160 video at 60 Hz across both displays during continuous use, with no frame drops observed when toggling between sources. USB 3.0 peripheral sharing runs at 5 Gbps without bandwidth throttling during long file transfers. Independent audio streams stay isolated per computer, preventing cross-talk. The 12 VDC 3 A supply delivers consistent power to all four upstream ports and the hub simultaneously.

Thermals noise and power draw

Passive cooling keeps the chassis silent in normal office ambient conditions; no fan noise is generated. The external 12 VDC 3 A adapter handles the full load of four connected systems, dual DisplayPort outputs, USB hub traffic and audio circuitry without thermal throttling. Surface temperatures remain low to the touch during extended sessions. Power consumption scales only with the number of active upstream connections.

Questions about this item

How much heat or noise does the KV6224DP produce when switching four computers all day?

The unit draws 12 VDC at 3 A with no internal fan, so it runs silently and generates only modest warmth during continuous operation.

Which cables must I already have to connect four PCs and two monitors to the KV6224DP?

You need eight DisplayPort cables for the video links, four USB Type-B cables for keyboard and mouse, and up to eight 3.5 mm audio cables if you want sound from every computer.

Will the KV6224DP work with older PCs that only output 1080p over DisplayPort 1.2?

Yes — the switch passes any DisplayPort 1.2 signal up to 3840 x 2160 at 60 Hz, so lower-resolution sources display normally on the dual 4K monitors.
