The cable has been extensively redesigned to be HDMI v1.3 compliant and to deliver the best picture and sound, especially over longer lengths. These new cables use heavier gauge conductors, silver-plated to optimise skin effect and improve high frequency transmission. Insulation is foamed polyethylene chosen for its performance over longer runs of cable where minimal loss of signal is critical.

Special attention was paid to the internal and overall shielding. Internal shields are dual aluminium Mylar foil and the overall shield is a combination of foil and braid. This delivers excellent high frequency shielding whilst retaining flexibility and minimising weight.

The plug surround has been redesigned with a lower profile to fit closely spaced sockets and to produce a more reliable connection. The new HDMI 1.3 Silver Plus has been tested against the highly rated original HDMI Silver Plus with a wide range of equipment (using projectors, plasma screens and LCD TVs). Colours are noticeably more vibrant, contrast is improved and images are sharper with lower noise giving a greater sense of perspective or depth of field.
