Mini DisplayPort

The Mini DisplayPort (MiniDP or mDP) is a miniaturized version of the DisplayPort digital audiovisual interface. The features and signals are the same.

Apple announced the launch of the Mini DisplayPort in October 2008. In 2013, Apple installed this port on all new Macintosh computers : MacBook, MacBook Pro, MacBook Air, iMac, Mac mini, Mac Pro.
The Mini DisplayPort is also installed on laptops from manufacturers such as Alienware (DELL), ASUS, Microsoft, Lenovo, Toshiba, MSI and HP.

HDMI is a fully digital audio/video interface that transmits uncompressed encrypted streams. HDMI is used to connect an audio/video source (DVD player, Blu-ray player, computer or game console) to a high-definition TV.
HDMI supports all video formats, including standard, improved, high-definition definition and multichannel sound. HDMI encapsulanses video data by TMDS. Initially, the maximum HDMI transmission......

The Mini DisplayPort connector, invented by Apple, is increasingly used, both in graphics cards (some AMD and Matrox models) and in computers (Apple, of course, but also Toshiba).
With the release of the Radeon 5870 EyeFinity and its six Mini DisplayPort connectors (expected March 11), let's go back to this connection.

The Mini DisplayPort is a smaller version of the DisplayPort. The video features are identical to those of DisplayPort, but audio features are not available on all devices.
There are several ways to plug a screen into a Mini DisplayPort socket : with a native screen, via a (passive) adapter to DisplayPort (and a screen to that standard), through an adapter to DVI

The other simple solution is to use an adapter to DisplayPort and plug in a rare and expensive DisplayPort display.

signal transmitted on a DP socket.
But this signal must be sent from the graphics card through a TMDS, a component generating the signal.
Small problem, besides the fact that this mode limits the signal to a single link (1,920 x 1,200), there are sometimes fewer TMDS than outputs.
AMD's EyeFinity card should have only two compatible outputs.

The USB bus is also said to \Hot pluggable\, that is to say that you can connect and disconnect a USB with the PC on. The system installed on the PC (Windows, linux...) recognizes it immediately. The USB has a very interesting feature : it's the mode standby when not using the device. Also known as \Power conservation\ : Indeed the USB bus gets suspended after 3 ms if it is no longer used. During this mode, the co......

In fact, the Mini DisplayPort is beginning to democratize in devices, but display devices are still too rare.
