Three-Source HDMI Switcher

The IOGEAR GHSW8431 connects three HDMI sources to one display, supporting true 4K resolution at 4096 x 2160 @ 60Hz with 4:4:4 chroma sampling. It handles uncompressed 7.1 LPCM, Dolby True HD and DTS-HD Master Audio signals. Front-panel push buttons, an IR remote and an auto-switch mode provide flexible source selection. The unit is HDCP 2.2 compliant and includes CEC support for integrated device control.

Sustained 18 Gbps Throughput

Video streaming runs at 18 Gbps without compression, maintaining full 4:4:4 colour fidelity during extended production sessions. LED indicators show power status and active port ID at a glance. A no-slip locking power mechanism secures the 5V/500mA supply against accidental disconnection. The metal chassis dissipates heat passively, so the switcher stays stable through long recording or streaming workloads.

Expands From Single-Input Displays

This switcher replaces a direct HDMI cable when a display or projector has only one input but the workflow requires three sources. Cascading up to three levels expands capacity to 27 source ports for larger installations. Buyers who need more than three simultaneous sources or require built-in scaling and format conversion should look at a multi-format production switcher instead.

Questions about this item

Does the GHSW8431 run hot or draw much power when left on all day?

It uses a 5V 500mA supply so power draw is very low and the compact metal case stays cool during continuous operation.

What cables or sources must I already have to use this switcher?

You need up to three HDMI source devices and one HDMI display or projector; all HDMI cables are user-supplied.

Will my older 1080p cameras and 4K monitor work together through the GHSW8431?

Yes, the switch passes 18 Gbps signals and supports HDCP 2.2 so mixed-resolution sources display correctly on a 4K screen.
