Four-input HDMI switch with audio extraction

The SMUGDESK 4×1 HDMI switch connects four HDMI sources to a single display and lets you change inputs with the included IR remote. It provides plug-and-play operation without any driver installation, making it suitable for home-theatre, gaming or conference setups where multiple devices share one screen.

Sustained 4K60 and 1080P120 transmission

A built-in signal-processing chip maintains lossless, lag-free video during extended sessions at 4K@60Hz or 1080P@120Hz, preventing colour deviation or frame dropping over time. The same chip keeps 3D video formats stable, so long playback or gaming periods remain consistent without signal degradation.

Independent audio outputs and ARC return

Optical SPDIF and 3.5mm jack extract audio from the HDMI stream for sound bars, amplifiers or headphones without using extra device ports. ARC compatibility sends TV audio back to an external system for surround sound, while the switch itself draws minimal power and operates silently in normal use.

Questions about this item

Does the 4K60 signal processor run silently and stay cool during all-day use?

The unit has no fan and draws minimal power through its HDMI ports, so it operates silently and remains cool to the touch even with continuous 4K60 video switching.

Which cables and audio gear must I already own to use the optical and 3.5mm outputs?

You need four HDMI source cables, one HDMI display cable, plus either a TOSLINK optical cable for digital audio or a 3.5mm stereo cable for analog speakers or headphones.

Will my older 1080P120 console and 4K60 streaming box work together on the same switch?

Yes, the switch handles 1080P120 and 4K60 signals simultaneously, auto-negotiating the best format for each input while sending a single stable stream to the display.
