Four-computer HDMI 2.0 KVM switch

This IHDAPP unit lets one keyboard, mouse and monitor control four computers through HDMI 2.0 and USB 3.0 connections. It is aimed at offices, classrooms, meeting rooms and home setups that need to juggle multiple PCs, laptops, consoles or streaming boxes from a single workstation. The switch also provides a USB 2.0 hub port for flash drives, scanners, printers or webcams.

Steady 4K 60 Hz output under load

The switch maintains full 18 Gbps bandwidth so 4K at 60 Hz with YUV4:4:4 chroma stays stable during long sessions, not just brief bursts. 1080p and 3D signals also pass through without degradation. Hot-key or front-panel switching changes sources instantly, keeping workflows smooth when moving between machines for extended periods.

Plug-and-play setup with hot-key control

No drivers are required; connect the four HDMI and USB cables, attach peripherals, and the unit is ready. Switching uses Scroll Lock+Scroll Lock+1-4 or Ctrl+Ctrl+1-4 sequences. The only common issue is forgetting the hot-key combo, so keep the cheat sheet handy until the sequence becomes muscle memory.

Questions about this item

Does the IHDAPP 4-port KVM switch need its own power supply or does it draw power from the connected PCs?

The switch is bus-powered through the USB 3.0 links to each computer, so no external power adapter is required and heat output stays negligible during all-day use.

What cables must I already have to connect four computers to this KVM switch?

You need four HDMI 2.0 cables and four USB 3.0 A-to-B cables — one pair per computer — plus a single HDMI cable from the switch to your monitor.

Will a PC that only outputs 1080p work correctly through the 4K 60Hz switch alongside newer 4K machines?

Yes, the switch supports 1080p and 3D as well as 4K@60Hz, so mixed-resolution sources share the same display without extra configuration.
