QR Code Link to This Post
**This is a FosPower 4x2 HDMI Matrix Switch/Splitter (4 inputs, 2 outputs).**
It's an older model (circa 2015–2018) that supports:
- **Ultra HD 4K** (at 30Hz)
- **Full HD 1080p**
- **3D**
- Audio extraction (optical SPDIF/Toslink and L/R RCA stereo outputs)
- Audio Return Channel (ARC)
- HDCP 1.4
- Includes IR remote control and external power adapter (the cord visible in the photo)
### What it does
A **matrix** allows you to route any of the 4 HDMI input sources (e.g., Blu-ray player, game console, cable box, streaming device) independently to either or both of the 2 HDMI outputs (e.g., TV + projector, or TV + audio receiver). It can also extract audio separately to an optical or analog sound system while passing video through.
The exact layout of the stickers ("3D Full HD 4K HDMI High-Definition Multimedia Interface") and the black rectangular design with front buttons/power indicator match this FosPower product line.
