DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA) to replace VGA, DVI, and FPD-Link. It was designed to be backwards compatible with DVI, VGA and HDMI, enabling users like gamers, businesses, and the medical imaging community to leverage the equipment they already have.
DisplayPort is commonly used to connect video sources to displays but can also be used to transfer audio and USB data. DisplayPort transmits video and audio data via micro-packet protocols. The micro-packets allow the clock signal to be embedded within the data stream, which results in higher resolutions. Using data packets gives the ability to increase the features of DP without the task of making changes to the connectors.
DisplayPort 1.2 is tested to a distance of 15 meters using a passive cable and up to 33 meters over an active cable. The capability of transmitting at 17.28 Gbit/s in High Bit Rate 2 (HBR2) mode allows for amplified resolutions, higher refresh rates, and greater depth of color. It also drives a single 4K Ultra HD display or up to four daisy-chainable monitors at 1920 x 1200 resolution.
With the various companion standards like Mini DisplayPort (mDP), Embedded DisplayPort (eDP) and Mobility DisplayPort (MyDP), you’re bound to find it on more computers, televisions, and phones.
Chassis Plans is at the forefront of design and is incorporating DisplayPort into their rugged LCD display products.
