Overview
The AV Access 4KSP12-S is an HDMI signal splitter with three HDMI ports arranged as one input and two outputs, sending a single 4K source to two displays at once at up to 4K and 60Hz. It carries the AV Access brand tech line.
Listed as a video converter, the port layout of one input and two outputs actually describes a splitter rather than a format converter, since it duplicates an HDMI signal instead of changing it between formats. That distinction matters for anyone shopping by what the box does rather than its category label.
- 1 HDMI input, 2 HDMI outputs
- Supports 4K at 60Hz
- AV Access brand
- 4 out of 5 average across 139 ratings
Who it's for
Useful for anyone feeding one HDMI source, such as a cable box or game console, to two TVs or a TV and a monitor at the same time. Not the right pick for someone who actually needs to convert between HDMI and a different video format like VGA or component.
Strengths and trade-offs
Drawn from this product's published specifications.
- Feeds two displays from a single 4K60 HDMI source
- Compact three-port design
- 4-star rating from 139 buyers
- Functions as a splitter, not a true format converter despite the listing name
- No cable length or HDCP compatibility details given
Performance notes
With three total HDMI ports split as one in and two out, the 4KSP12-S mirrors the same signal to both outputs rather than scaling or converting it, so both connected displays need to support the source's resolution and refresh rate, up to 4K at 60Hz here, for a clean picture.
