Overview
A compact black HDMI switching unit built around 9 HDMI ports, letting several video sources share one display. At 1.2 lb, it is meant to sit inside a media cabinet rather than take up shelf space.
Listed as a video converter, but the spec that matters here is the port count: 9 HDMI connections point to a multi-source HDMI switch rather than a format-conversion box. Anyone routing a game console, streaming box, and cable box into one TV is the intended use case.
- 9 HDMI ports
- Black housing
- 1.2 lb
- J-Tech Digital branded
Who it's for
Fits a home theater setup with more HDMI devices than the TV has inputs. Not the right pick for someone who needs to convert between HDMI and a legacy format like component or VGA.
Strengths and trade-offs
Drawn from this product's published specifications.
- Consolidates multiple HDMI sources into one output
- Compact, lightweight housing
- Input and output port split not detailed
- No stated resolution or HDR support
Performance notes
With 9 HDMI ports on a 1.2 lb chassis, the unit is built to route signals between several sources and a single output rather than power or process video on its own.
