Micro DisplayPort would have targeted systems that need ultra-compact connectors, such as phones, tablets and ultra-portable notebook computers. This standard would have been physically smaller than the currently available Mini DisplayPort connectors. The standard was expected to be released by Q2 2014. [84] DDM [ edit ] The tables below describe the refresh frequencies that can be achieved with each transmission mode. In general, maximum refresh frequency is determined by the transmission mode (RBR, HBR, HBR2, HBR3, UHBR 10, UHBR 13.5, or UHBR 20). These transmission modes were introduced to the DisplayPort standard as follows: eDP 1.0 was adopted in December 2008. [86] It included advanced power-saving features such as seamless refresh rate switching. 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.DisplayPort 1.4, however, takes things a much greater step further. It supports 1440p resolution up to 240Hz and even 4K at up to 120Hz. It also supports 5K resolution at up to 60Hz, and even 8K resolution at 30Hz. The DisplayPort 1.4 standard was first published in March 2016. While it didn't introduce any new transmission modes and did not increase the available bandwidth or data rate, it maintained the strong showing from DisplayPort 1.3. DisplayPort 1.4 has a maximum total bandwidth of 32.4Gbps and a maximum total data rate of 25.92Gbps. That gives it enough bandwidth to handle a 4K UHD stream at up to 120Hz with 24-bit/px color, or a 5K display at up to 60Hz, with 30-bit/px color. It even supports 8K video, but only at up to 30Hz due to the hefty bandwidth demands. New DisplayPort(TM) Interface Standard for PCs, Monitors, TV Displays and Projectors Released by the Video Electronics Standards Association". Video Electronics Standards Association (VESA). 3 May 2006. Archived from the original on 14 February 2009. 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. [21] 1.4 [ edit ]

Ultimately DisplayPort 1.4 vs. HDMI 2.1 is a debate that largely comes down to using what’s best available. If you have a display and device that support HDMI 2.1, chances are they’re designed with it in mind and you’ll get the best experience using an HDMI 2.1 cable. Alternatively, if your gaming PC supports DisplayPort 1.4 and you have a compatible monitor, then using that will get you the best experience. Support for HDR video was introduced in DisplayPort 1.4. It implements the CTA 861.3 standard for transport of static HDR metadata in EDID. [22] Content protection [ edit ] Audio data is transmitted across the main link during the video blanking intervals (short pauses between each line and frame of video data).
