Four SDI output mini-connectors are provided for SDI formats. For single-link SDI, a single,
mirrored output is provided on both the SDI 3 and SDI 4 connectors. For dual-link SDI, the dual
output is provided on the SDI 3 and SDI 4 connectors. For Quad HD or 4K SDI, all four of the

equipment to the SDI outputs.
