The Video Electronics Standards Association has codified the standard for the next version of DisplayPort , and the little , orchard apple tree - loving HDMI contender , and it just have a quite a little more interesting . Like , multiple - monitor - on - one - plug interesting .
The construct of daisy - chaining multiple monitors on one DisplayPort connection has been part of the vision all along , but reading 1.2 will be the first to actually indorse the applied science — at this microscope stage , up to four at a time , at a resolution of 1920 x 1200 . On top of that , it ’ll bring full HD , 120fps - per - duct 3D bread and butter , a 21.6Gbps data rate , and bi - directional USB datum , meaning that anything colligate to a DisplayPort 1.2 cable could serve as a high - bandwidth USB hub .

Milpitas , Calif. , Jan. 18 , 2010 — The Video Electronics Standards Association ( VESA ) today officially unveiled the industry ’s most innovative and conciliatory digital communicating interface standard for channel exhibit , audio recording and other information .
VESA ’s DisplayPort Version 1.2 is a comprehensive propagation to the original DisplayPort criterion provide many fresh benefits to the death user . Benefits let in : double the datum rate of the premature DisplayPort v1.1a standard ( enabling higher performance 3D stereo display , higher resolving power and color depth , and fast refresh pace ) ; multiple monitor support from a screen background or notebook computer computer using only one DisplayPort connector ; the ability to channelize USB data between a microcomputer and Display , confirm Display USB functions such as a webcam and USB hub . DisplayPort v1.2 is backward compatible with exist DisplayPort v1.1a systems , including existing cable and the Mini DisplayPort connexion .
DisplayPort v1.2 increase performance by double the maximum data transfer rate from 10.8 Gbps ( Giga - bits - per - second ) to 21.6 Gbps , greatly increase display resolution , color deepness , refresh rates , and multiple display capabilities .
DisplayPort v1.2 confirm “ multi - streaming ” — the ability to transport multiple sovereign uncompressed display and audio frequency streams over a exclusive cable television , supporting protect content and mellow execution applications such as 3D play . This enables the use of multiple monitors connected by overseas telegram in a daisy range of mountains or hub contour . Whereas the current Display v1.1a criterion can support one 2560 x 1600 proctor at 60Hz , DisplayPort v1.2 can back two such monitor with one cable , or four 1920 x 1200 monitors . Many other combination are possible , let in multiple video informant , multiple display ( even at different resolutions ) and multiple audio speakers .
Another new feature film is the ability to abide high - speed , bi - directional data transfer , provide USB 2.0 or Ethernet information to be carry within a standard DisplayPort cable . For DisplayPort v1.2 , the maximum data rate of this “ AUX ” channel has been increased from 1 Mbps ( Mega - bit - per - moment ) to 720 Mbps , providing desirable bandwidth for USB 2.0 . The DisplayPort cable can therefore abide USB data to / from the display to support Display USB function , in addition to send the video and audio information . Standard Ethernet can also be send in the DisplayPort cable .
DisplayPort v1.2 was project to be compatible with existing DisplayPort systems and cables . To take advantage of the young capacity , a personal computer will need to be DisplayPort v1.2 enabled , however existing standard cables can still be used , include those with the new Mini - DisplayPort connecter . To achieve the 21.6 Gbps rate , the per - lane data rate is replicate from 2.7 Gbps to 5.4 Gbps , over the four lanes that exist in the standard cable television service . For a single display , this enables up to 3840 x 2400 resolution at 60Hz , or a 3D show ( 120Hz ) at 2560 x 1600 .
DisplayPort v1.2 also impart new audio enhancement including the following :
— Audio Copy Protection and category code
— High definition audio formats such as Dolby MAT , DTS HD , all Blu - Ray
formatting , and the DRA touchstone from China
— Synchronization assist between audio frequency and video , multiple audio duct , and
multiple audio sump devices using Global Time Code ( GTC )
DisplayPort v1.2 also includes improved financial backing for Full HD 3D Stereoscopic displays :
— lifetime - like motion using up to 240 frames - per - second in full HD , providing 120
frames - per - second for each eye
— 3D Stereo transmission format support
field of operations sequential , side by side , pixel interleaved , dual interface , and pile
— 3D Stereo display capability resolution
Mono , Stereo , 3D Glasses
“ DisplayPort is a really clear , flexible , extensible multimedia system interconnect standard that is ubiquitous in the PC , notebook computer and display markets and is rapidly profit traction in consumer electronics applications , ” say Bill Lempesis , VESA ’s executive manager . “ DisplayPort Version v1.2 offers a complete set of welfare and capableness that no other standard can provide . It is entirely backward compatible with DisplayPort v1.1a and require no new cables or other equipment , making it the standard of choice across the diligence .
