Four-computer HDMI KVM switch
The IHDAPP 8401A lets a single HDMI monitor, keyboard and mouse control up to four computers or laptops. It accepts four HDMI inputs and one HDMI output, with front-panel push buttons and a 1.5-metre wired remote for source selection. LED indicators show the active port at a glance.
Bundled cables and power adapter
Four USB 3.0 cables and a DC 12V power adapter are included so every connected system receives both video and USB data links immediately. The switch provides four downstream USB 3.0 ports running at 5Gbps for peripherals such as printers or cameras, while remaining compatible with USB 2.0 and 1.1 devices.
HDMI 2.1 bandwidth and switching delay
The unit passes 8K at 60Hz, 4K at 144Hz, 120Hz and 60Hz with YUV 4:4:4 colour, plus 1080p at 165Hz, and is backward compatible with lower resolutions. Using USB-C-to-HDMI or DisplayPort-to-HDMI adapters will reduce the achievable resolution, and each source change incurs an approximate 8-second delay.

Questions about this item
Will the USB 3.0 ports or HDMI 2.1 circuitry need any periodic replacement?
No user-replaceable parts are inside the 8401A; the DC 12V adapter and the four supplied USB 3.0 cables are the only items that may wear out over time.
At 8K 60 Hz or 4K 144 Hz, which limit appears first during long sessions?
The 8-second switching delay is the first bottleneck you will notice when changing sources repeatedly; video bandwidth itself is rated for 8K@60Hz and 4K@144Hz continuously.
How much heat or fan noise does the 270 g unit produce when running all day?
The metal case runs warm but stays silent because there is no fan; the external 12 V power brick handles the conversion heat away from the desk.
