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.

The acronym "HDMI" stands for "High Definition Multimedia Interface".

The HDMI interface allows transmission of video and audio between devices, supporting video resolutions 480i, 480p, 576i, 576p, 720p, 1080i, 1080p, 1440p, 1600p.

Type HDMI

Type A (picture 1): It is the standard connector used in almost all devices.
Type B (picture 2): A connector rarely used.
Type C (picture 3): A connector widely used in tablets, smartphones and other devices.
Type D (picture 4): A connector used in smartphones.
Type E (picture 5): IA connector used for vehicles connectivity.

One hertz is one cycle per second, meaning repeating cycle as an event. For example, hertz is applied physics measuring the number of times for a second wave (either acoustic or electromagnetic) is repeated or can be applied, among other uses, to ocean waves that reach the Beach vibrations per second or a solid. The quantity that measures the frequency hertz is called,in this regard, the inverse of the period. One hertz is an oscillation frequency of suffering a particle over a period of one second.

1080p is an alternative name for the maximum resolution used in high definition television (HDTV). The number 1080 represents 1080 lines of vertical display resolution, while the letter p stands for progressive scan and non-interlaced.

Gbps (Gb/s, Gbit/s) is the speed with which information is transmitted. It is normally used to measure the speed information in the ADSL/fiber addresses transmitted.

• 1 Gb/s is equivalent to 1,000,000,000 b/s.
• 1 Gb/s is equivalent to 1000000 kb/s.
• 1Gb/s equals 1000 Mb/s.

The meaning would be HDTV. It is used to indicate that the device is compatible with high definition. For high definition they have created three technical standards. ATSC, DVB and ISDB-T. Since 2005 the possibility of assigning HD Ready label as a kind of obligation to define the devices that have more than 720 lines (720p, 1080i at 50 or 60 Hz) was assessed.
