HDMI 2.0, referred to by some manufacturers as HDMI UHD, was released on September 4, 2013. [112] HDMI 2.0 increases the maximum bandwidth to 18.0 Gbit/s. [112] [113] [114] HDMI 2.0 uses TMDS encoding for video transmission like previous versions, giving it a maximum video bandwidth of 14.4 Gbit/s. This enables HDMI 2.0 to carry 4K video at 60 ...
DisplayPort 1.2 has more bandwidth at 21.6 Gbit/s [77] (17.28 Gbit/s with overhead removed) as opposed to HDMI 2.0's 18 Gbit/s [78] (14.4 Gbit/s with overhead removed). DisplayPort 1.3 raises that to 32.4 Gbit/s (25.92 Gbit/s with overhead removed), and HDMI 2.1 raises that up to 48 Gbit/s (42.67 Gbit/s with overhead removed), adding an ...
Version 1.1 was released in March 2009 and was followed by version 1.2 released in August 2011. Version 1.3 was released in June 2013 [ 1 ] and current version 2.0 was released in September 2017. DisplayID uses variable-length structures of up to 256 bytes each, which encompass all existing EDID extensions as well as new extensions for 3D ...

DisplayPort supports 3840 × 2160 at 30 Hz in version 1.1 and added support for up to 75 Hz in version 1.2 (2009) and 120 Hz in version 1.3 (2014), [49] while HDMI added support for 3840 × 2160 at 30 Hz in version 1.4 (2009) [50] and 60 Hz in version 2.0 (2013). [51]
The update includes native encoding of 4:2:2 and 4:2:0 formats in six-pixel containers, 14/16 bits per color, and minor modifications to the encoding algorithm. On 4 January 2017, HDMI 2.1 was announced which supports up to 10K resolution and uses DSC 1.2 for video that is higher than 8K resolution with 4:2:0 chroma subsampling .
The physical phenomena on which the device relies (such as spinning platters in a hard drive) will also impose limits; for instance, no spinning platter shipping in 2009 saturates SATA revision 2.0 (3 Gbit/s), so moving from this 3 Gbit/s interface to USB 3.0 at 4.8 Gbit/s for one spinning drive will result in no increase in realized transfer rate.
