8K HDMI 2.1 Switch 4x1 with Optical Audio Extractor - Multi-Input

In this review the 8K HDMI 2.1 Switch 4x1 with Optical Audio Extractor is judged as a practical choice for users who need to connect multiple consoles and media players to a single display while keeping separate digital audio out. The bottom line: it is best for gamers and home theater builders who value high-resolution video pass-through and a dedicated optical SPDIF output for sound systems. The reviewer found the unit reliable for high-bandwidth signals and convenient to operate with the included IR remote, though users wanting HDMI audio extraction or full ARC/e-ARC compatibility should look elsewhere.

Key Features

• 4 inputs to 1 output: Lets users switch up to four HDMI sources into a single HDMI display, reducing cable swaps and simplifying a console-heavy setup.
• 8K and 4K/120Hz pass-through: Supports very high resolutions and refresh rates so modern consoles and PCs can deliver their peak video performance through one device.
• Optical SPDIF audio extractor: Provides a dedicated digital audio output to feed soundbars and older receivers that rely on optical inputs.
• Wide codec support: Handles LPCM, Dolby and various DTS formats, plus advanced formats such as Dolby TrueHD and DTS-HD Master Audio for multichannel sources.
• Remote and IR control: Includes an IR remote and works with common programmable remotes, making source selection quick without reaching the device.
• Cross-platform compatibility: Functions with Windows, Mac OS and Linux devices as well as game consoles and streaming players.

Who It's For

The switch is ideal for gamers and media enthusiasts who run multiple HDMI sources like PS5, Xbox, streaming boxes and Blu-ray players and who need a separate optical audio feed to older receivers or soundbars. It suits users who must preserve high-resolution video up to 8K and 4K at 120Hz while keeping wiring tidy.

It is not the right choice for people who need audio extraction over HDMI or full Sonos-ARC/e-ARC support, or for users who require HDMI audio extraction to send multichannel audio back over HDMI. Also, anyone dependent on full VRR ranges beyond the reported limitations should verify compatibility first.

Our Verdict

The 8K HDMI 2.1 Switch 4x1 with Optical Audio Extractor is a solid value for users who prioritize high-resolution video switching and need a separate optical audio feed for legacy receivers or soundbars.
