a b c d e f g h i j k DisplayPort Standard, Version 1, Video Electronics Standards Association (VESA), 1 May 2006 The DisplayPort main link is used for transmission of video and audio. The main link consists of a number of unidirectional serial data channels which operate concurrently, called lanes. A standard DisplayPort connection has 4 lanes, though some applications of DisplayPort implement more, such as the Thunderbolt 3 interface which implements up to 8 lanes of DisplayPort. [39] :4 The differences between single-link and dual-link refer to how much bandwidth the cable can carry. A single-link DVI-D or DVI-I cable can carry 3.96 Gbit/s, which tops out at 1,920 x 1,200 resolution. Dual-link, on the other hand, physically has extra pins on the connectors, allowing a maximum bandwidth of 7.92 Gbit/s and 2,560 x 1,600 resolution. Although DVI is still a common connection, it’s becoming dated, so if you want to output a very high resolution you’ll need to use HDMI or DisplayPort instead. DisplayPort ( DP) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). It is primarily used to connect a video source to a display device such as a computer monitor. It can also carry audio, USB, and other forms of data. [1]
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.

Most motherboards and dedicated graphics cards will have multiple outputs. You can use a combination of these to output to multiple monitors. So if you have HDMI and DVI outputs, connect one monitor using HDMI and the other using DVI. As mentioned above, if you’re using DisplayPort and your graphics card or device supports Multi-Stream Transport, you can daisy-chain DisplayPort and USB-C monitors, too. One 8K ( 7680 × 4320) display @ 30 Hz and 10 bpc (30 bit/px, HDR) RGB/Y′C BC R 4:4:4 color (uncompressed) HDMI 2.0 has an Audio Return Channel (ARC), which means you only need a single HDMI cable to send audio from a TV to your soundbar or AV receiver. HDMI 2.1 also has an Enhanced Audio Return Channel (eARC), which allows you to send uncompressed, high-quality audio from your TV to your soundbar or AV receiver.The DisplayPort standard does not specify any maximum length for cables, though the DisplayPort 1.2 standard does set a minimum requirement that all cables up to 2 meters in length must support HBR2 speeds (21.6 Gbit/s), and all cables of any length must support RBR speeds (6.48 Gbit/s). [37] :§5.7.1, §4.1 Cables longer than 2 meters may or may not support HBR/HBR2 speeds, and cables of any length may or may not support HBR3 speeds or above.

Where appropriate, incorporate items into the main body of the article. ( November 2010) HDMI 2.1: Supports resolutions up to 10K and also has dynamic HDR (High-dynamic-range) and enhanced Audio Return Channel (eARC). DisplayPort 1.0 includes optional DPCP (DisplayPort Content Protection) from Philips, which uses 128-bit AES encryption. It also features full authentication and session key establishment. Each encryption session is independent, and it has an independent revocation system. This portion of the standard is licensed separately. It also adds the ability to verify the proximity of the receiver and transmitter, a technique intended to ensure users are not bypassing the content protection system to send data out to distant, unauthorized users.

pins for the auxiliary channel – the auxiliary channel uses another 3-pin shielded twisted pair (pins 15–17) That sounds a bit confusing, so let’s use the Capshi cable’s stats to explain: 8K@60Hz, 4K@144Hz, 1080P@240Hz. At a refresh rate of 60Hz (60 frames per second), you can get an 8K resolution, while at a refresh rate of 240Hz you can only get 1080P.
