How is DisplayPort different from HDMI
They are different technically as they were designed for different markets. HDMI was made primarily for home entertainment systems and is used widely on HDTVs as an AV interface. Some PCs and monitors include HDMI to enable connectivity with HDTVs. However HDMI has limitations. In most cases it is fine but for really high resolutions and frame rates, other options might be better e.g. DisplayPort. Most HDMI cables are short (1-2 m) and you might need to use a signal booster to cover a long distance.
DisplayPort is a newer standard originally developed to support the higher performance requirements of personal computers, enabling an increase in performance and integration. It provides a more robust and stable AV link. DisplayPort can deliver 4K video over a length up to 2m using a passive cable. A 15m passive cable limits resolution to 1080p and it should manage up to 2560 x 1600 – pixel resolution over 5m.
