The DisplayPort standard is the cornerstone of the PC display standard and has been revised several times since it was first introduced more than a decade ago. This morning, the DisplayPort 2.0 specification was officially released, and the standard once again achieved a huge leap.
The new version of DisplayPort has almost tripled the available bandwidth of DisplayPort 1.4, and many of the previous optional features were moved to the new core standards.
The current version of DisplayPort 1.3 and 1.4 can provide up to 32.4 Gbps of bandwidth, effective 25.9 Gbps, and can achieve 16.7 million colors (24-bit) 4K@120Hz, but it is still not enough for next-generation displays, including Apple's new 6K Pro Display XDR display. In addition, HDMI Forum has also launched HDMI 2.1. To meet these challenges, VESA officially released the DisplayPort 2.0 standard.
The fastest mode in DisplayPort 2.0 will reach 80 Gbps of raw bandwidth, which is about 2.5 times that of DisplayPort 1.3 / 1.4. In addition, DisplayPort 2.0 introduces a more efficient coding scheme to improve coding efficiency. The effective bandwidth of the new standard will reach a peak of 77.4 Gbps, which is three times that of the previous generation.
DisplayPort 2.0 is very fast, supports 8K displays without any compression (including chroma subsampling), and can output 8K video in 30-bit color format, even in high resolution. Similarly, it is also possible to output a 10K display in 24-bit color without compression and a 16K display in compression.
