Dual-mode DisplayPort can anon afford single-link HDMI and DVI signals application a simple acquiescent adapter that adjusts for the lower voltages appropriate by DisplayPort.323 If dual-mode chipset detects that a DVI or HDMI acquiescent adapter is attached, it switches to DVI/HDMI approach which uses the 4-lane capital DisplayPort hotlink and the AUX approach hotlink to address 3 TMDS signals, a Clock arresting and Affectation Abstracts Approach data/clock. Dual-mode ports are apparent with the DP++ logo; a lot of accepted DisplayPort cartoon cards and monitors abutment this mode.10
A notable limitation is that dual-mode can alone address single-link DVI/HDMI, as the amount of pins in the DisplayPort adapter is bereft for dual-link connections; an alive advocate is bare for Dual-Link DVI (and analog basic video such as VGA, back it employs agenda to analog conversion). Alive about-face can be powered by +3.3 V wire in the DisplayPort connector, but some alive adapters crave alien power.24
VESA foresees that all HDMI and DVI about-face will eventually be handled by alive adapters which act as DisplayPort Sink devices, in adjustment to facilitate easier updates to latest HDMI and DisplayPort specs, and abutment dual-link HDMI,10 DisplayPort access with either beneath than 4 lanes or altered abstracts rates, and assorted DisplayPort streams. It should be acclaimed that DVI 1.0 blueprint was accomplished in 1999 and the DVI industry bunch has back disbanded, so approaching updates to DVI blueprint are unlikely; also, although dual-link HDMI Type B adapter is authentic in the HDMI specification, it has not apparent any applied use as of 2012.

This commodity contains anchored lists that may be ailing defined, counterfeit or indiscriminate. Please advice to apple-pie it up to accommodated Wikipedia's superior standards. (November 2010)
In December 2010 it was appear that several computer vendors and affectation makers including Intel, AMD, Dell, Lenovo, Samsung and LG would activate phasing out abutment for LVDS, VGA and DVI-I over the next few years affective advanced with developing technologies DisplayPort and HDMI as their replacements.2526. One notable barring to the account of manufacturers is Nvidia, who has yet to advertise any affairs apropos approaching abutment of bequest interfaces.
Legacy interfaces such as VGA, DVI and LVDS accept not kept pace, and newer standards such as DisplayPort and HDMI acutely accommodate the best connectivity options affective forward. In our opinion, DisplayPort 1.2 is the approaching interface for PC monitors, forth with HDMI 1.4a for TV connectivity.

DisplayPort has several advantages over VGA, DVI and LVDS.
Opencitation needed (except HDCP), royalty-free and adaptable accepted to advice ample adoption
Beneath lanes with anchored self-clock, bargain EMI with abstracts scrambling and advance spectrum mode
Based on a micro-packet protocol
Allows simple amplification of the accepted with assorted abstracts types
Flexible allocation of accessible bandwidth amid audio and video
Assorted video streams over individual concrete affiliation (version 1.2)
Long-distance manual over another concrete media such as optical cilia (version 1.1a)
Supports top resolution displays and assorted displays with a individual cable
17.28 Gbit/s of able video bandwidth, abundant for acknowledging 4 accompanying 1080p60 displays (CEA-861 timings) or 2,560 × 1,600 × 30 bit @120 Hz (CVT-R timings)note 1
Designed to abutment centralized chip-to-chip communication
Aimed at replacing centralized LVDS links to affectation panels with a unified hotlink interface
Compatible with low-voltage signaling acclimated with sub-nanometer CMOS fabrication
Can drive affectation panels directly, eliminating ascent and ascendancy circuits and acceptance for cheaper and slimmer displays
Hotlink training with adjustable amplitude and preemphasis adapts to differing cable lengths and arresting quality
Bargain bandwidth manual for 15 beat cable (at atomic 1920x1080p60, 24 bpp)
Full bandwidth manual for 2 beat cable
High-speed abetting approach for DDC, EDID, MCCS, DPMS, HDCP, adapter identification etc. traffic
Can be acclimated for transmitting bi-directional USB, touch-panel data, CEC, etc.
Self-latching connector
edit Comparison with HDMI
Although DisplayPort supports abundant of the aforementioned functionality as HDMI, it is accepted to accompaniment the HDMI interface, not alter it.34 DisplayPort can afford HDMI video and audio application acquiescent adapters affiliated to Dual-mode ports, and supports HDCP agreeable aegis acclimated in the HDMI standard.
Most of DisplayPort's supporters are computer companies including Apple, Dell, HP, Lenovo, Fujitsu, Toshiba and Acer, which intend DisplayPort to alter DVI, VGA and LVDS in their computers and monitors.
DisplayPort is currently ability free, while the HDMI ability is 4 cents per accessory and has an anniversary fee of $10,000 for top aggregate manufacturers.28 HDMI Licensing counters by claiming that "royalty-free" does not necessarily beggarly free, and that the DisplayPort blueprint makes it accessible to appeal advantage from any article that accouterments the technology.29 DisplayPort has added than alert the bandwidth with up to 21.6 Gbit/s30 (17.28 Gbits/s with aerial removed) as against to HDMI's 10.2 Gbits/s31 (8.16 Gbits/s with aerial removed), and can allotment this bandwidth with assorted streams of video and audio to abstracted devices.32
DisplayPort in built-in approach lacks some appearance present in HDMI, such as abutment for the xvYCC blush amplitude (added in DisplayPort adaptation 1.2) and Customer Electronics Ascendancy (CEC) commands, which acquiesce to ascendancy assorted accessories through a individual remote;3334 VESA asserts that CEC commands can be transmitted over the AUX approach if needed.1032 HDMI uses different Vendor Specific Block anatomy which allows for specific appearance such as added blush spaces, about these can be authentic by CEA EDID extensions.

Since its addition in 2006, DisplayPort has boring acquired acceptance aural the computer industry, and as of 2010, DisplayPort connectors are featured on abounding clear cards, displays, and anthology computers.
edit ATI/AMD
AMD Cartoon Product Group (former ATI Technologies) was the aboriginal aggregation to absolution customer articles with a DisplayPort alpha with their 790G chipset and Radeon HD 2000 alternation cartoon cards. The aboriginal were apparent at AMD's Technology Analyst Day on July 25, 2007. AMD after implemented the DisplayPort on the GPU dent in Radeon HD 3600 and HD 3400 cartoon products, apparent at AMD Financial Analyst Day on 13 December 2007. These articles accustomed DisplayPort acceptance from VESA in March 2008.35
In 2008, DisplayPort connectors were featured on abounding cartoon cards based on the ATI/AMD HD 4000 series. In 2009, the HD 5000 alternation cartoon cards congenital a DisplayPort adapter as a accepted feature, forth with two Dual-link DVI connectors and a HDMI connector. The Eyefinity versions can backpack up to six Mini DisplayPort connectors.36 Abutment for DisplayPort audio was alien by AMD in the Catalyst 9.12 hotfix.37
As of February 2011, the latest HD 6000 alternation cartoon cards affection abutment for DisplayPort 1.2, acceptance daisy-chaining assorted monitors from the aforementioned connector. A DisplayPort hub absolute three Dual-link DVI connectors is aswell available.

On 14 October 2008, Apple alien several articles featuring a Mini DisplayPort38 as the sole video connector. This adapter was proprietary at that time. Later, with versions 1.1a and 1.2 of the specification, it became allotment of the standard. Amid October 2009 and February 2011, all Mac models affection Mini DisplayPort connector; during that time iMac, MacBook, MacBook Air, MacBook Pro, and Xserve models acclimated Mini DisplayPort as their sole video achievement while the Mac Mini and Mac Pro models had both a Mini DisplayPort and either a DVI anchorage (Mac Pro) or an HDMI anchorage (Mac Mini). On February 24, 2011 MacBook Pros began shipment with Thunderbolt (known ahead by Intel codename Light Peak) which provides both DisplayPort and PCI Express functionality in a individual port. On May 3, 2011 Apple alien their aboriginal iMac calendar with Thunderbolt congenital in. The iMac 21 in (53 cm) accustomed one and the iMac 27 in (69 cm) accustomed two Thunderbolt ports.
Apple's 24 in (61 cm) and 27 in (69 cm) LED Cinema Displays affection Mini DisplayPort connector. The 27-inch iMac alien in 2009 accustomed the Mini DisplayPort to act as an input, axis the iMac into a standalone display.39 2011 iMacs abutment this 'Target Affectation Mode' via the Thunderbolt port, but alone if the antecedent is aswell able with Thunderbolt.40
