4-Port HDMI 2.1 KVM Switch
This IHDAPP 8401B switch lets four HDMI 2.1 computers share one monitor, keyboard and mouse. It is built for offices, teaching rooms, monitoring setups and home theatres where desk space is limited. Each computer connects with one HDMI and one USB 3.0 cable. No driver installation is required on Windows, macOS, Linux, Chrome OS or Unix systems.
Passive thermals and 12 V DC power
The unit ships with a 12 V DC adapter and runs without active cooling. In normal switching use it draws only the power needed for signal processing and the four USB 3.0 ports. LED indicators show the active port without adding audible noise. The compact 7.5 x 3 x 2 inch enclosure stays cool during typical desktop workloads.
Sustained 8K 60 Hz and 5 Gbps throughput
Under continuous operation the switch maintains 8K at 60 Hz, 4K at 144 Hz or 120 Hz, and YUV 4:4:4 colour. The four USB 3.0 ports sustain 5 Gbps data rates for drives, cameras or peripherals. Switching between sources takes roughly eight seconds whether using the front button or the 1.5 m wired remote.

Questions about this item
How do I connect the four computers to the 8401B and which step is often missed?
Connect each computer with one HDMI 2.1 cable and one USB 3.0 cable to the rear ports, then plug the included 12V power adapter into the KVM before turning anything on; the step people miss is powering the switch first.
What maintenance will the 8401B need over time?
No scheduled maintenance is required; keep the vents clear, check that the four USB 3.0 cables and the 1.5m wired remote stay firmly seated, and replace any cable that shows wear.
What limit appears first during long sessions at high resolution?
The 8-second switching delay becomes noticeable before any thermal or bandwidth limit when changing sources at 8K 60Hz or 4K 144Hz.
