The DisplayPort standard does not specify any maximum length for cables, though the DisplayPort 1.2 standard does set a minimum requirement that all cables up to 2 meters in length must support HBR2 speeds (21.6 Gbit/s), and all cables of any length must support RBR speeds (6.48 Gbit/s).
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
Active cables are typically priced 5 to 10 times higher than passive cables. [12] Some active cables are only produced by a single manufacturer and sold through a single distributor. Some critics argue that active cables do not provide power savings for signal processing reasons; in an active cable design, there is at least one extra integrated ...
It can also carry audio, USB, and other forms of data. DisplayPort is backward compatible with other interfaces such as HDMI and DVI through the use of active or passive adapters. Male Mini DisplayPort plug Mini DisplayPort: Proposed alternative to HDMI, used with computer displays: (VGA, DVI) Apple Inc.'s successor to their own Mini-DVI.
[18] [19] They also stated: "Legacy interfaces such as VGA, DVI and LVDS have not kept pace, and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward. In our opinion, DisplayPort 1.2 is the future interface for PC monitors, along with HDMI 1.4a for TV connectivity".
SlimPort is a proprietary alternative to MHL, based on the DisplayPort standard integrated into common Micro-USB ports, and supports up to 1080p60 or 1080p30 with 3D content over HDMI 1.4 (up to 5.4 Gbit/s of bandwidth), in addition to support for DVI, VGA (up to 1920 × 1080 at 60 Hz), and DisplayPort.
HDMI Type A socket. High-Definition Multimedia Interface (HDMI) is a compact audio/video standard for transmitting uncompressed digital data. There are three HDMI connector types. Type A and Type B were defined by the HDMI 1.0 specification. Type C was defined by the HDMI 1.3 specification.
A Dual-DVI breakout cable can be used in connection with two passive DVI-to-HDMI adapters to feed modern displays with HDMI inputs, while using a DMS-59 graphics card, since the DVI signals are electrically identical to HDMI signals and do not require any kind of conversion.
