Four-Port HDMI 2.1 KVM Switch

The IHDAPP KVM switch lets four computers share a single HDMI monitor and four USB 3.0 peripherals. It supports video resolutions up to 8K at 60 Hz and is backward compatible with 4K at 60 Hz, 1440p at 120 Hz and 1080p at 240 Hz. The unit includes a wired remote and push-button switching for convenient host selection.

Sustained Operation with External Power

A supplied 12 V DC adapter powers the switch so signal integrity remains stable during long sessions across all four ports. Each connected PC requires both an HDMI 2.1 cable and a USB 3.0 cable for full keyboard, mouse and peripheral sharing. LED indicators show the active port at a glance without software overhead.

Compact Metal Enclosure and Cabling

The chassis measures 19 by 7.5 by 2 cm and weighs 350 g, fitting neatly on a desk or mounting behind a monitor. Four 1.5 m USB A cables and a 1.5 m wired remote are included, reducing cable clutter. Hotkey switching is not supported, so users rely on the physical buttons or remote for changes.

Questions about this item

Does the 12 V power adapter keep the switch cool and quiet during all-day use?

The unit ships with a 12 V DC adapter for stable operation; it has no fan, so it runs silently and produces minimal heat under normal load.

Which cables must I already have to connect four PCs to the HDMI 2.1 and USB 3.0 ports?

Each computer needs its own HDMI 2.1 cable and a USB-A to USB-B cable; the box includes four 1.5 m USB 3.0 cables but no HDMI cables.

Will my older 1080p 240 Hz monitor work through the 8K@60 Hz HDMI 2.1 output?

Yes — the switch is backward compatible with 1920 x 1080 at 240 Hz, 2560 x 1440 at 120 Hz, 4K at 60 Hz and 30 Hz, so legacy displays are supported.
