The DisplayPort and HDMI digital signals use bitrate encoding of some form — 8b/10b for most of the older standards, 16b/18b for HDMI 2.1, and 128b/132b for DisplayPort 2.0. 8b/10b encoding for example means for every 8 bits of data, 10 bits are actually transmitted, with the extra bits used to help maintain signal integrity (eg, by ensuring zero DC bias). DisplayPort cables differ in their transmission speed support. DisplayPort specifies seven different transmission modes (RBR, HBR, HBR2, HBR3, UHBR 10, UHBR 13.5, and UHBR 20) which support progressively higher bandwidths. Not all DisplayPort cables are capable of all seven transmission modes. VESA offers certifications for various levels of bandwidth. These certifications are optional, and not all DisplayPort cables are certified by VESA. VESA Releases DisplayPort 1.3 Standard: 50% More Bandwidth, New Features". www.anandtech.com .

Mini - commonly used for the DisplayPort output on notebook PCs including Apple products which includes Thunderbolt. Benefits of DisplayPort The host system's software also needs to support MST for hubs or daisy-chains to work. While Microsoft Windows environments have full support for it, Apple operating systems currently do not support MST hubs or DisplayPort daisy-chaining as of macOS 10.15 ("Catalina"). [56] [57] The DisplayPort AUX channel is a half-duplex (bidirectional) data channel used for miscellaneous additional data beyond video and audio, such as EDID ( I 2C) or CEC commands. [8] :§2.4 This bidirectional data channel is required, since the video lane signals are unidirectional from source to display. AUX signals are transmitted across a dedicated set of twisted-pair wires. DisplayPort 1.0 specified Manchester encoding with a 2 MBd signal rate (1 Mbit/s data rate). [8] :§3.4 Version 1.2 of the DisplayPort standard introduced a second transmission mode called FAUX (Fast AUX), which operated at 720 MBd with 8b/10b encoding (576 Mbit/s data rate), [37] :§3.4 but it was deprecated in version 1.3. It should also be noted that the use of Display Stream Compression (DSC), introduced in DisplayPort 1.4, greatly reduces the bandwidth requirements for the cable. Formats which would normally be beyond the limits of DisplayPort 1.4, such as 4K (3840 × 2160) at 144 Hz 8 bpc RGB/Y′C BC R 4:4:4 (31.4 Gbit/s data rate when uncompressed), can only be implemented by using DSC. This would reduce the physical bandwidth requirements by 2–3×, placing it well within the capabilities of an HBR2-rated cable.DisplayPort version 1.3 was approved on 15 September 2014. [19] This standard increases overall transmission bandwidth to 32.4 Gbit/s with the new HBR3 mode featuring 8.1 Gbit/s per lane (up from 5.4 Gbit/s with HBR2 in version 1.2), for a total data throughput of 25.92 Gbit/s after factoring in 8b/10b encoding overhead. This bandwidth is enough for a 4K UHD display ( 3840 × 2160) at 120 Hz with 24 bit/px RGB color, a 5K display ( 5120 × 2880) at 60 Hz with 30 bit/px RGB color, or an 8K UHD display ( 7680 × 4320) at 30 Hz with 24 bit/px RGB color. Using Multi-Stream Transport (MST), a DisplayPort port can drive two 4K UHD ( 3840 × 2160) displays at 60 Hz, or up to four WQXGA ( 2560 × 1600) displays at 60 Hz with 24 bit/px RGB color. The new standard includes mandatory Dual-mode for DVI and HDMI adapters, implementing the HDMI 2.0 standard and HDCP 2.2 content protection. [20] The Thunderbolt 3 connection standard was originally to include DisplayPort 1.3 capability, but the final release ended up with only version 1.2. The VESA's Adaptive Sync feature in DisplayPort version 1.3 remains an optional part of the specification.

Video Electronics Standards Association (VESA). 26 June 2019. In December 2010, several computer vendors and display makers including Intel, AMD, Dell, Lenovo, Samsung and LG announced they would begin phasing out FPD-Link, VGA, and DVI-I over the next few years, replacing them with DisplayPort and HDMI.

This format can only be achieved uncompressed if the YC BC R format with either 4:2:2 or 4:2:0 chroma subsampling (as noted) is used UHBR 10: 4 × 10.0 Gbit/s = 40.00 Gbit/s bandwidth (data rate of 38.69 Gbit/s or 4.84 GB/s with 128b/132b encoding and FEC) Choose HDMI 2 if DisplayPort isn’t available or if you require audio over 144Hz (as DVI doesn’t support audio) DSC can provide up to a 3:1 compression ratio by converting to YCgCo and using delta PCM encoding. It provides a "visually lossless" (and sometimes even truly lossless, depending on what you're viewing) result. Using DSC, 8K 120 Hz HDR is suddenly viable, with a bandwidth requirement of 'only' 42.58 Gbps.

How are DisplayPort Cables Classified?

If you want to combine the graphics outputs of your motherboard and your dedicated graphics card, this can be possible with certain Intel processors. This uses a “hybrid multi-monitor” mode but will be dependent on the chipset and possibly the motherboard used. You might also need to upgrade the BIOS to get it working. Intel lists the following chipsets as compatible in this hybrid mode: Hybrid multi-monitor support is officially supported with Intel Embedded Graphics Drivers for systems using the Intel Q45/G41/G45 and GM45/GL40/GS45 chipsets, or later.

The maximum limits for the RBR and HBR modes are calculated using standard data rate calculations. [50] For UHBR modes, the limits are based on the data efficiency calculations provided by the DisplayPort standard. [51] :§3.5.2.18 All calculations assume uncompressed RGB video with CVT-RB v2 timing. Maximum limits may differ if compression (i.e. DSC) or Y′C BC R 4:2:2 or 4:2:0 chroma subsampling are used.
