Whats the difference between HDMI 1.0 and HDMI 1.3?
Since HDMI technology first appeared, specifications have changed. All later HDMI specifications are backwards-compatible with previous specifications, meaning a HDMI 1.3 cable includes all the capabilities of a HDMI 1.0 cable. The later versions of HDMI cables have higher speed, color, connector and other abilities. These improvements have been made for HDMI cables to prepare for future improvements and capabilities of HD devices.
