One 8K ( 7680 × 4320) display @ 30 Hz and 10 bpc (30 bit/px, HDR) RGB/Y′C BC R 4:4:4 color (uncompressed)
One 16K ( 15360 × 8640) display @ 60 Hz with 10 bpc (30 bit/px, HDR) RGB/Y′C BC R 4:4:4 color (with DSC) DisplayPort version 1.2a was released in January 2013 [15] and may optionally include VESA's Adaptive Sync. [16] AMD's FreeSync uses the DisplayPort Adaptive-Sync feature for operation. FreeSync was first demonstrated at CES 2014 on a Toshiba Satellite laptop by making use of the Panel-Self-Refresh (PSR) feature from the Embedded DisplayPort standard, [17] and after a proposal from AMD, VESA later adapted the Panel-Self-Refresh feature for use in standalone displays and added it as an optional feature of the main DisplayPort standard under the name "Adaptive-Sync" in version 1.2a. [18] As it is an optional feature, support for Adaptive-Sync is not required for a display to be DisplayPort 1.2a-compliant. Both HDMI and DisplayPort have published specification for transmitting their signal over the USB-C connector. For more details, see USB-C §Alternate Mode partner specifications. Mini DisplayPort (mDP) is a standard announced by Apple in the fourth quarter of 2008. Shortly after announcing Mini DisplayPort, Apple announced that it would license the connector technology with no fee. The following year, in early 2009, VESA announced that Mini DisplayPort would be included in the upcoming DisplayPort 1.2 specification.

Unavailable on USB-C– The DisplayPort Alternate Mode specification for sending DisplayPort signals over a USB-C cable does not include support for the dual-mode protocol. As a result, DP-to-DVI and DP-to-HDMI passive adapters do not function when chained from a USB-C to DP adapter.
A mini DisplayPort was first introduced by Apple in 2008. Today, you can find a port for it in most Apple products, and in some PC Notebooks from Microsoft, MSI, Lenovo, and more. A miniature DisplayPort is extremely compatible with ThunderBolt, which is commonly used in Apple sources. HDR can be described as the ratio between the lightest and darkest parts of an image. Typically, with standard dynamic range, you’re losing detail at either end of the light spectrum. Expose a scene for the shadow detail and you end up with blown-out highlights or expose for the highlights and you lose shadow detail. HDR allows a greater range of detail across the full light spectrum.

Optional; 1–8 channels, 16 or 24-bit linear PCM; 32–192 kHz sampling rate; maximum bitrate 36,864 kbit/s (4,608 kB/s) In addition, individual devices may have their own arbitrary limitations beyond transmission speed. For example, NVIDIA Kepler GK104 GPUs (such as the GeForce GTX 680 and 770) support "DisplayPort 1.2" with the HBR2 transmission mode, but are limited to 540 Mpx/s, only 3⁄ 4 of the maximum possible with HBR2. [49] Consequently, certain devices may have limitations that differ from those listed in the following tables. Mobile High-Definition Link is an interface created for portable devices including mobile phones. MHL can be thought of as a spin-off version of HDMI. It was first proposed by Silicon Image which also had a significant contribution in the development of HDMI. Color depth of 8 bpc (24 bit/px or 16.7 million colors) is assumed for all formats in these tables. This is the standard color depth used on most computer displays. Note that some operating systems refer to this as "32-bit" color depth—this is the same as 24-bit color depth. The 8 extra bits are for alpha channel information, which is only present in software. At the transmission stage, this information has already been incorporated into the primary color channels, so the actual video data transmitted across the cable only contains 24 bits per pixel.
The first version, 1.0, was approved by VESA on 3 May 2006. [6] Version 1.1 was ratified on 2 April 2007, [7] and version 1.1a was ratified on 11 January 2008. [8] a b c d e Although this format slightly exceeds the maximum data rate of this transmission mode with CVT-R2 timing, it is close enough to be achieved with non-standard timings

HDMI does not natively support MST. However, you can use a DisplayPort hub with an HDMI adapter to daisy-chain multiple HDMI monitors through the DisplayPort on your computer. Talking about cables, they come in standard and high-speed cable options, both with and without an ethernet link. HDMI also implements content protection via HDCP. Moreover, a single remote control can be used to control various CEC (Consumer Electronics Control)-enabled devices connected over HDMI. pins for the auxiliary channel – the auxiliary channel uses another 3-pin shielded twisted pair (pins 15–17) There are now cards with DisplayPort 2.1 support, but they're still of different levels. Intel's Arc GPUs support 10 Gbps per lane, for a 40 Gbps maximum connection speed (not including 128b/132b encoding). AMD opted for the faster 13.5 Gbps per lane (54 Gbps total), but neither company supports the potential 20 Gbps per lane variant. But perhaps the bigger issue now isn't GPU support. In version 2.1, VESA introduced the DP40 and DP80 cable certification tiers, which validate cables for UHBR10 and UHBR20 speeds respectively.
Because the standard has evolved over the years, not all DisplayPort cables will work properly at the latest speeds. The original Display 1.0-1.1a spec allowed for RBR (reduced bit rate) and HBR (high bit rate) cables, capable of 5.18 Gbps and 8.64 Gbps of data bandwidth, respectively. DisplayPort 1.2 introduced HBR2, doubled the maximum data bit rate to 17.28 Gbps and is compatible with standard HBR DisplayPort cables. HBR3 with DisplayPort 1.3-1.4a increased things again to 25.92 Gbps, and added the requirement of DP8K DisplayPort certified cables.
Updates to HDMI have kept the standard relevant for over 18 years. The earliest versions of HDMI have become outdated, but later versions have increased bandwidth and features. All features of DisplayPort will function across any DisplayPort cable. DisplayPort does not have multiple cable designs; all DP cables have the same basic layout and wiring, and will support any feature including audio, daisy-chaining, G-Sync/ FreeSync, HDR, and DSC. The DP8K certification was announced by VESA in January 2018, and certifies cables for proper operation at HBR3 speeds (8.1 Gbit/s per lane, 32.4 Gbit/s total). [43]
