VGA its full name is "Video Graphics Array" interfaces, we usually also known as D-Sub interface, but also output analog signal interface.

A High BandwidthIn the high-definition video to be popular,What is DisplayPort interface? Articles there is no high-bandwidth display interface is unable to gain a foothold. DisplayPort's inception, it can provide bandwidth up to 10.8Gb / s. You know, HDMI 1.2a bandwidth only 4.95Gb / s, even if the latest release of HDMI 1.3 bandwidth provided (10.2Gb / s) is also less in the DisplayPort 1.0. DisplayPort supports WQXGA + (2560 × 1600), QXGA (2048 × 1536) resolution, etc. and 30/36bit (per color 10/12bit) color depth, sufficient bandwidth to ensure the future of large-size display devices for higher resolution requirements.(2) maximize the integration of peripheral devicesAnd, like HDMI, DisplayPort also allows audio and video signals share a cable transmission, support a variety of high-quality digital audio. But is more advanced than HDMI, DisplayPort in a cable can achieve more. Outside the four main transmission channel, DisplayPort also provides a powerful auxiliary channel. The auxiliary channel transmission bandwidth of 1Mbps, maximum delay of only 500¼s, as a direct voice, video and other low-bandwidth data transmission channel, the other can also be used to control the game without delay. See, DisplayPort peripherals can achieve the greatest degree of integration and control.3 takes all internal and external interfaces Main product:HDMI Converter is with good quality.Currently DisplayPort external-type connector, there are two: one is the standard type, similar to USB, HDMI and other joints; Another is low-profile, mainly for connecting the limited area of applications, such as ultra-thin notebooks. Two kinds of external connectors longest distance can reach 15 meters, although this distance to be less than the number of HDMI, but connectors and wiring related specifications have been prepared for future upgrades, even if the future introduction of new 2X speed DisplayPort standard (21.6 Gbps), connectors and wiring do not have to re-design.In addition to realize the connection between the device and the device outside, DisplayPort interface can also be used inside the device, and even chip-to-chip data interface. For example, DisplayPort on the "conspiracy" to replace LCD panel and the drive circuit board interface between the mainstream - LVDS (Low Voltage Differential Signaling, low voltage differential signaling) interface position. The internal type connector DisplayPort only 26.3mm wide, 1.1mm high, 30% smaller than the LVDS interface, but the transmission rate of 3.8 times is LVDS.
