- The HDMI cable must be a high-speed cable that is compliant with the HDMI 2.0 specification (or higher). The 2.0 specification is important to achieve the correct frame rate and resolution. While a lesser cable (such as HDMI 1.4) might display video, it may not display at the proper frame rate and/or resolution.
- The S/PDIF is the optical port. This particular variety of S/PDIF uses a TOSLINK optical connection and cable.
