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.

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.

Thunderbolt is called the cable used by Apple for the transmission of video, considered one of the fastest technologies for laptops in terms of data transmission.

Its development is based on the PCI Express and Displayport architecture.

They are capable of transferring data, high definition video and voltage. Able to reach up to 10 Gb/s in both directions, a speed 20 times faster than a USB 2.0 or 12times faster than a firewire cable.

Currently we can find Thunderbolt technology with 10 GB/s, Thunderbolt 2 with speeds higher than 20 gb/s and Thunderbolt 3 with speeds of 40 GB/s and up to 15 W of voltage.

With Thunderbolt 3 we will have compatibility with HD devices like 4k or 5K screens.
