Apple Moves Smaller with Mini DisplayPort
The Mini DisplayPort interface is a smaller version of the traditional DisplayPort plug and connector, and was first publicly announced by Apple in 2008. Apple products featuring the Mini DisplayPort connector include the MacBook family of laptops, the iMac, Mac Mini, Mac Pro and the entire Apple Cinema line of displays. The user-friendly Mini DisplayPort connector links the Mac to an LED display, and offers both video and audio support, significantly reducing the number of cables associated with incorporating an external display and speakers.
Mini-DVI vs. Mini DisplayPortUnlike Mini-DVI and Micro-DVI predecessors, the Mini DisplayPort is capable of displaying the high resolutions commonly associated with 30 inch and larger displays. Large displays are becoming more common as DisplayPort integrators Dell and Apple recently released 30 inch product offerings. Laptops with a Mini DisplayPort can connect a computer with to an external display or projector with a VGA or DVI interface by using an adapter.
In early 2009, VESA announced that it would include Mini DisplayPort in the DisplayPort 1.2 specification.
DisplayPort TestingWorking with an independent test lab for DisplayPort testing will help developers build properly functioning DisplayPort products. DisplayPort test categories include:
Physical Layer Test
Link Layer Test
Electrical Test
HDCP Test
The DisplayPort compliance & logo program ensures that products comply with DisplayPort standard guidelines. The DisplayPort Certified Logo ensures that certified products are of high quality and that they will work together seamlessly.
DisplayPort: An Emerging A/V Interconnect
DisplayPort, an audio-video interconnect standard, is designed to advance display simplicity and the adoption of protected digital outputs on computers. This allows users to easily view commercial HD content and other protected files.
Because DisplayPort signaling can transmit both DVI and HDMI signals (other digital display standards), DisplayPort is compatible with many popular interconnects and subsequently, the consumer devices that utilize the standards. What this means for consumers is the easy incorporation of DisplayPort sources or devices in their homes and offices.
The DisplayPort interface, developed for computers, monitors and home-theater systems by the Video Electronics Standards Association (VESA), and formally approved in 2006, includes DisplayPort Content Protection (DPCP). This content protection capability uses 128-bit encryption and features full authentication and session key establishment. For consumers this means that even commercially protected content will play back over the DisplayPort interface, ensuring a seamless user experience.
DisplayPort technology appears to be gaining momentum. According to a 2008 report from industry analyst firm In-Stat; DisplayPort is predicted to reach the milestone of more than 600 million products shipped by 2012. The DisplayPort Web site lists more than 165 members of VESA, a veritable who’s who of the consumer electrics and PC industries. Many of these companies have announced their intention to implement or support DisplayPort technology into their products. Some notable industry heavyweights, like Dell, for example, already have numerous displays shipping with DisplayPort technology.
DisplayPort TestingWorking with an independent test lab accredited by VESA to perform DisplayPort testing helps ensure that Display Port products will function properly, which is especially essential with consumer video applications.
While VESA does not require certification of DisplayPort products, it is highly encouraged. The DisplayPort Certified Logo reassures end users that certified products will interoperate properly and provide a quality digital display experience.
