Compatibility Guide

This device is a generic HDMI accessory, so it works with most HDMI-equipped gear. However, keep these points in mind:

  • HDMI cable: You will need separate HDMI cables. For stable 4K transmission, a High Speed HDMI cable (18Gbps or higher) is recommended.
  • Power: It runs on bus power from the HDMI port, but if you experience instability, connect a micro-USB power cable (5V/1A adapter not included) for reliable operation.
  • HDCP: HDCP is supported, but some protected 4K streaming content may not display correctly.
  • Splitter mode resolution: In splitter mode, both displays will output at the lower of the two resolutions.

Ideal Use Cases

  • Switch between TV and projector: Share one source (like a Fire TV Stick or game console) between your living room TV and a projector.
  • Multi-console gaming: Connect PS5, Nintendo Switch, and PC to one monitor and switch between them effortlessly.
  • Conference rooms: Switch between a laptop and tablet on a single projector during presentations.
  • Simple dual-monitor setup: Mirror your PC screen to two monitors using splitter mode.

Important Notes

  • No 4K/60Hz: This unit supports up to 4K/30Hz. For 4K/60Hz, look for an HDMI 2.0-compatible device.
  • HDMI 1.4b equivalent: It does not support HDMI 2.0 bandwidth features like HDR or higher refresh rates.
  • Heat: The unit may become warm during extended use, which is normal.
  • Power adapter sold separately: A micro-USB cable is included, but you will need your own 5V/1A USB power adapter if bus power is insufficient.
