Extend Your HDMI Connection Without Buying a Longer CableThis HDMI coupler (F/F) extends your 8K audio/video application by connecting two 8K-capable HDMI cables to create one longer connection. The compact coupler fits in the palm of your hand and features molded gold-plated connectors to ensure top signal transfer. It is compatible with all HDMI cables, so you can use the coupler with lower resolution equipment, but 8K cables are necessary to achieve 8K resolutions.
