DisplayPort is the name of a digital interconnect interface intended for video transmission between a computer and its monitor.

One of the best features of the DisplayPort technology is its high resolution, allowing 4096 x 2160 pixels maximum resolution.

HD is the term used to differentiate the systems that generate, transmit or support HD content (High Definition) with those of standard definition or low definition (SD).

HD resolutions are usually at least 1280 x 720 pixels by taking the ratio "width x height". Being the height, 720 pixels, which make high resolution.

The ATA (Advanced Technology Attachment English) or PATA interface, originally known as IDE (Integrated Device Electronics) is an interface standard for connecting devices massive data storage and optical drives that uses the standard ATA derivative and the ATAPI standard.
