HDMI (High-Definition Multimedia Interface) and DisplayPort are both digital interface standards used to transmit video and audio data from a source device to a display device. HDMI is commonly used in consumer electronics, such as TVs and DVD players, while DisplayPort is primarily used in computer and professional displays.DisplayPort has some features that HDMI does not, such as support for a higher maximum resolution, more audio channels, and the ability to transmit data over a longer distance. Both HDMI and DisplayPort use a similar type of connector and can be converted to one another using an adapter.
