HDMI Female to Female Coupler

Join two male-ended HDMI cables with a compact female-to-female coupler supporting HDMI 1.4b features and verified 4K video modes.

Female-to-female HDMI coupling

Connects two standard male-ended HDMI cables to extend an existing cable run or bridge an installation point.

HDMI 1.4b capability

Supports up to 10.2Gbps bandwidth, 3D video and verified 4K modes when the complete link supports them.

Audio and control support

Passes compatible multichannel audio, ARC, CEC and HDCP 1.4 signals through the joined link.

Passive installation

No power, drivers or software are required; performance depends on the total cable run and connected equipment.

Why this model fits the job

Join two male-ended HDMI cables with a compact female-to-female coupler supporting HDMI 1.4b features and verified 4K video modes. The design focuses on the exact connector, signalling and compatibility requirements shown in the current StarTech.com specification, helping buyers select the right part without relying on broad compatibility claims.

Compatibility checklist

Use two male-ended HDMI cables and ensure every device and cable supports the required resolution, refresh rate and HDMI feature.
Treat the two cables and coupler as one total link; longer runs can reduce the achievable bandwidth or resolution.
This coupler extends a physical HDMI connection and does not convert HDMI to another interface.

Common applications

Join two existing HDMI cables
Bridge an HDMI wall plate or equipment relocation
Keep a compact HDMI extension coupler in an AV service kit
