4-Port HDMI 2.1 KVM Switch for Multi-System Control

This KVM switch connects four HDMI-equipped computers to a single monitor, keyboard and mouse. It suits professionals and enthusiasts who need to operate multiple desktops, laptops or consoles from one workstation without swapping cables. The device supports HDMI 2.1 input and output for modern high-resolution sources.

Passive Metal Chassis with External 12 V Power

The unit uses a metal case that doubles as a heat sink and provides ESD protection. An included DC 12 V power adapter supplies the switching logic and the four USB 3.0 ports, keeping the chassis cool and silent during normal operation. No internal fans are present.

8K@60 Hz and 4K@144 Hz HDMI 2.1 Bandwidth

The single specification that decides suitability is the HDMI 2.1 link supporting 8K at 60 Hz and 4K at 144 Hz with YUV 4:4:4 colour. If your monitor and graphics cards require this bandwidth, the switch will pass the signal; if you only need lower resolutions, the same ports remain backward compatible.

Questions about this item

How do I install the Hitoor 4-port HDMI 2.1 KVM switch and what step is often missed?

Connect each of the four computers using the supplied USB 3.0 cables and HDMI 2.1 cables, attach the monitor to the single HDMI output, plug in the 12 V power adapter, then link the 1.5 m wired remote. The step often missed is powering the unit before switching — without the adapter the switch will not change ports.

What maintenance or replacement will the Hitoor KVM switch need later?

No routine maintenance is required. If a USB 3.0 cable or the 1.5 m wired remote becomes damaged, replace it with a cable rated for 5 Gbps or a matching remote. The metal chassis and ESD protection are designed for continuous operation without service intervals.

What limit appears first during sustained 8K@60 Hz use on this KVM switch?

The primary limit is cable length — the supplier notes that shorter HDMI 2.1 cables ensure stable 8K@60 Hz transmission, so long cables may cause flicker or black screen before the switch itself reaches any thermal or bandwidth ceiling.
