The LG-HSW401-4K is an ultrathin auto switcher designed for managing multiple HDMI video sources. It features four HDMI inputs and one HDMI output, supporting high-resolution video up to 4Kx2K@60Hz 4:4:4 HDR and multichannel audio. The device is fully compliant with HDMI 2.0 and HDCP2.3 specifications, offering an 18Gbps high bandwidth for reliable signal transmission.
The primary function of the LG-HSW401-4K is to switch between four HDMI input sources and output the selected signal to a single HDMI display. Beyond simple switching, it incorporates advanced audio and EDID management capabilities. The switcher can de-embed digital stereo audio, providing an analog audio source via a 3.5mm mini stereo audio jack, which is useful for integrating with existing audio systems. A notable feature is its support for Audio Return Channel (ARC) on HDMI Input 4, allowing audio from the connected display to be sent back to an HDMI input port, typically for an AV amplifier.
The device offers flexible control options, including a front panel "Auto/Source" button, an IR remote control, and RS232 commands. In auto-switch mode, it automatically detects and switches to a newly connected source. If an active source is removed, it defaults to the first available active input. Manual switching is also available via the front panel button or remote.
