DisplayPort Testing - Ensuring Compatibility For Consumers

DisplayPort is an audio-video interconnect accepted that is advised to beforehand affectation artlessness and the acceptance of adequate agenda outputs on computers. This allows users to calmly appearance HD agreeable and added adequate files. Because DisplayPort signaling can abode both DVI and HDMI signals (other agenda affectation protocols), DisplayPort is accordant with abounding accepted interconnects and subsequently, the customer accessories that use the standards. For consumers, this agency they can calmly absorb DisplayPort sources or accessories in their homes and offices.
The DisplayPort interface standard, authentic by the Video Electronics Standards Association (VESA), an alignment that promotes acclimation in the affectation segment, is a agenda audio/video interconnect for computers, monitors and home-theater systems. The alignment aswell determines accepted sizes for collapsed console affectation mounts in accession to added acclimation efforts. Formally accustomed in 2006, DisplayPort includes DisplayPort Agreeable Aegis (DPCP). This agreeable aegis adequacy uses 128-bit encryption and appearance abounding affidavit and affair key establishment. For consumers, this agency that even commercially adequate agreeable will play aback over the DisplayPort interface, ensuring a seamless user experience.
DisplayPort Adaptation 1.1 added abutment for high-bandwidth agenda agreeable aegis (HDCP) to anticipate artful of agenda audio and video agreeable as it campaign beyond DisplayPort access to a affectation device. HDCP is aswell acclimated in added types of connections, such as HDMI.
PC manufacturers developed DisplayPort to abode accretion apropos and alter the alien analog video cartoon arrangement (VGA) interfaces in PC and LCD monitors and in customer electronics equipment. Additionally, DisplayPort offers added capabilities over alien agenda beheld interface (DVI) connectors begin in devices. It aswell aims to alter internal, board-to-display low voltage cogwheel signaling (LVDS) links in accessories with a unified hotlink interface.
DisplayPort technology appears to be accepting momentum. According to a 2008 address from industry analyst close In-Stat; DisplayPort is predicted to ability the anniversary of added than 600 actor articles alien by 2012. The DisplayPort Web website lists added than 165 associates of VESA, a actual who's who of the customer electrics and PC industries. Abounding of these companies accept appear their ambition to apparatus or abutment DisplayPort technology into their products. Some notable industry heavyweights, like Dell, for example, already accept abundant displays shipment with DisplayPort technology.
Mini DisplayPort - Apple drives abate anatomy factor
The Mini DisplayPort interface is a abate adaptation of the acceptable DisplayPort bung and connector, and was aboriginal about appear by Apple in 2008. Apple articles featuring the Mini DisplayPort adapter cover the MacBook ancestors of laptops, the iMac, Mac Mini, Mac Pro and the absolute Apple Cinema band of displays. DisplayPort replaced the DVI and mini-DVI interfaces begin on antecedent ancestors of Macs. The convenient Mini DisplayPort adapter links the Mac to an LED Display, and offers both video and audio support, abbreviation the amount of cables associated with accumulation an alien affectation and speakers.
Unlike Mini-DVI and Micro-DVI predecessors, the Mini DisplayPort is able of announcement the top resolutions frequently associated with 30 inch and beyond displays. Large displays are acceptable added common. DisplayPort integrators Dell and Apple afresh appear 30 inch artefact offerings. Laptops with a Mini DisplayPort can affix a computer to an alien affectation or projector with a VGA or DVI interface by application an adapter. While the Mini DisplayPort and approved DisplayPort signals are identical, their connectors are different, and to affix Mini DisplayPort to a approved DisplayPort or carnality versa requires an adapter.
In aboriginal 2009, VESA appear that it would cover Mini DisplayPort in the DisplayPort 1.2 specification. The DisplayPort 1.2 blueprint is advancing to be accomplished by VESA by the end of this year. The DisplayPort 1.2 blueprint offers appearance including:
--- 2X the acceleration of the DisplayPort 1.1a specification
--- Multiple beck abutment over one connector
--- Optional college acceleration abetting approach which enables bi-directional aggregate abstracts alteration over one DisplayPort cable
--- Added abutment for DisplayPort Mini-connector
--- Backward affinity with DisplayPort adaptation 1.1a
DisplayPort Testing
Working with an absolute analysis lab accepted by VESA to accomplish DisplayPort testing helps ensure that Affectation Port articles will action properly, which is abnormally capital with customer video applications. DisplayPort acquiescence & logo affairs testing guarantees that articles will accede with DisplayPort accepted guidelines.
DisplayPort analysis categories include:
--- Physical Layer Test
--- Hotlink Layer Test
--- Electrical Test
--- HDCP Test
While VESA does not crave acceptance of DisplayPort products, it is awful encouraged. Once a manufacturer's accessory is certified, the architect obtains the appropriate to use the DisplayPort logo. The DisplayPort Certified Logo reassures end users that certified articles will interoperate appropriately and accommodate a superior agenda affectation experience.
Related Tests
Tests accompanying to the DisplayPort analysis include:
--- HDMI Acquiescence Test: The HDMI acquiescence analysis ensures Top Definition Multimedia Interface (HDMI) articles will action properly.
--- Customer Electronics Control Analysis (CEC test): CEC is one of the functions authentic aural the HDMI blueprint 1.2a. This analysis verifies that the CEC action of a artefact will accomplish correctly.
--- HDCP Acquiescence Analysis for HDMI or DisplayPort products: This analysis determines whether or not HDCP accomplishing meets assertive specific requirement.
--- sRGB Acquiescence Program: Articles that canyon all sRGB tests will be accepted use of the sRGB logo. This logo shows end users that the affectation has been activated by an absolute third-party analysis lab.
