DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA) to transmit video and audio from a source device to a display. Designed to replace older interfaces like VGA and DVI, DisplayPort offers higher performance, versatility, and scalability, making it a preferred choice in IT environments for connecting computers to monitors, projectors, and other display devices.
Introduced in 2006, DisplayPort 1.0 supported a maximum bandwidth of 10.8 Gbps over four lanes, sufficient for 2560×1600 resolution at 60Hz. Version 1.1a added support for fiber-optic cables and improved interoperability.
Released in 2010, DisplayPort 1.2 doubled the bandwidth to 21.6 Gbps, enabling 4K resolution at 60Hz. It also introduced Multi-Stream Transport (MST), allowing multiple displays to be connected through a single port.
DisplayPort 1.3, launched in 2014, increased bandwidth to 32.4 Gbps, supporting 5K displays at 60Hz. Version 1.4 added Display Stream Compression (DSC) 1.2, Forward Error Correction, and HDR10 metadata support, enhancing video quality and efficiency.
Announced in 2019, DisplayPort 2.0 significantly boosted bandwidth to 80 Gbps, accommodating 8K resolution at 60Hz without compression. Subsequent versions, including 2.1 and 2.1b, improved integration with USB4 and introduced new cable certifications like DP40 and DP80 for higher data rates and longer cable lengths.
