A Digital Transmission

It is an interface for digital displays which specifically for computer monitors. It is developed by the Video Electronics Standards Association or also known as VESA. It is a high-performance replacement for other display modes such as VGA and DVI. The DisplayPort takes advantage of packetized data transmission similar to the technology employed in both the USB and Ethernet connections. This is extensible and supports a high resolution with a right number of connector pins. Like the HDMI, it can transmit video and audio data, either individually or simultaneously.

Important Factors Needed

Mini DisplayPort- It is a compact version of the DisplayPort connector introduced by Apple in 2008. This is free to license and in 2009 it was included in the official DisplayPort 1.2 spec. In 2011, both Apple and Intel announced the Thunderbolt format. It uses the same physical connector but significantly different protocols. This can also be adapted to and from DisplayPort with a passive adapter.

Dual-Mode and Multimode DisplayPort- Dual Mode- This is use to output either DisplayPort, HDMI, or Single-Link DVI from the same port. When using this the Passive adapters can be used to make the conversion. It is typically smaller and cheaper than the Active variety, and don't require external power. The Passive adapters are limited to resolutions that the DisplayPort device's Multi-Mode implementation supports, instead of the maximum resolution the device is capable of outputting via DisplayPort.

VGA vs DVI- Both VGA and DVI are called the legacy formats that preceded DisplayPort. The DisplayPort outclasses both DVI and VGA in terms of bandwidth, versatility, and ease of use. VGA's has a longer range compared to the DVI though it comes at the cost of maximum resolution. DisplayPort both supports a DVI or VGA display via passive adapters.

Thunderbolt- It is a computer interface which was co-developed by Intel and Apple. This is a combination of both DisplayPort and PCI Express into one connection which is called the Mini DisplayPort connector. The Thunderbolt 3 physical form factor has been updated to use USB Type-C. The Thunderbolt is generally faster and more versatile than DisplayPort, but is limited in cable length, and typically more expensive.

DisplayPort vs HDMI- The DisplayPort and HDMI tend to be roughly equal in performance and capability, with HDMI edging out DisplayPort as the more popular format, and DisplayPort winning slightly in overall performance, also depending on its version. The jack from the DisplayPort can be adapted for use with an HDMI display using this adapter, but connecting a DisplayPort display to an HDMI source can be more difficult.

Maximum Length- The DisplayPort is for full bandwidth transmission at 10ft and reduced functionality up to 50ft.

Active and Passive DisplayPort adapters- The Passive adapters only converts the physical format of the connector. The Active adapters actually transcode the signal and change the physical format. It can be passively converted to Single-Link DVI and HDMI. For the VGA, Dual-Link DVI, and other formats it requires an Active adapter.
