HDMI 2.1 Splitter 1×2 8K with Audio Extractor

HDMI 2.1 Splitter 1×2 8K with Audio Extractor

This HDMI 2.1 splitter takes one HDMI source and sends it to two displays at the same time, while also extracting the audio so it can play through a separate sound system. It answers a common setup problem: a games console, streamer or Blu-ray player that needs to feed a television and a projector — or a TV in two rooms — without swapping cables, and with the sound routed to a soundbar or amplifier that the displays alone cannot serve properly.

The splitter is built to the HDMI 2.1 specification in the listing, with 8K capability and support for 4K at 120 Hz on compatible high-refresh displays. The audio extractor separates the soundtrack from the video path, so an older AV receiver or a soundbar without the newest HDMI inputs can still receive the audio while the displays get the full-resolution picture.

Key features

• 1 input to 2 outputs — duplicates one HDMI source onto two displays simultaneously
• HDMI 2.1 specification for current consoles, streamers and players
• 8K support, with 4K at 120 Hz for high-refresh gaming displays
• Built-in audio extractor for soundbars, amplifiers and speaker systems
• Mirroring format — both displays show the same feed at the same time
• Suits gaming, home theatre and dual-display setups

How it behaves in a system

A splitter mirrors; it does not extend. Both outputs carry the same picture and sound, at a format both displays can accept — when the two displays have different capabilities, the shared format is the one they have in common. That makes this unit the right tool for a TV-plus-projector room, a main screen plus a second screen for an audience, or a gaming display mirrored to a capture or viewing monitor.

Audio extraction

The extractor exists for systems whose audio path is older than their video path. A console can send 4K/120 or 8K video straight to the display while the extracted audio feeds an amplifier or soundbar that could never pass that video through. Check the extractor’s output format on the unit supplied against your sound system’s inputs before finalising the installation.

Installation notes

Use certified HDMI cables of sensible length on both outputs — at HDMI 2.1 bandwidths, cable quality decides stability more than the splitter does. Power the unit from the supplied adapter, connect the displays first and the source last, and test the complete path at the highest format you plan to use (8K, or 4K at 120 Hz) before closing up the installation.

For dual-display rooms that also need proper sound, this one box replaces a tangle of manual cable swapping with a permanent, tidy split.

Ownership notes

Label the cables at both ends when the splitter goes into a rack or behind a television — future troubleshooting starts with knowing which output feeds which display. Keep the unit ventilated, use its supplied power adapter rather than a random USB supply, and record the format settings that worked (resolution, refresh, colour depth) in the room’s documentation. Small habits like these are what make a permanently installed splitter a fit-and-forget component instead of a recurring puzzle.
