Cable guide: Displayport


DisplayPort (DP) and Mini display port (MDP) are two connectors that are beginning to emerge in more and more graphics cards and monitors. The only different between the contacts, the physical size. Just as HDMI has become the replacement for Scart, it seems like DisplayPort is the replacement for DVI. DisplayPort has in fact many benefits, including the connector is much smaller and handier. In addition, the standard developed by Vesa and they take, unlike HDMI, no license fees from product manufacturers who choose to use the connector.

Advantages of DisplayPort:

  • The contact has in some cases a locking feature (optional).
  • The connector attaches automatically and released by pressing a button (instead of the screws on the VGA and DVI).
  • Support for audio transmission, but it is up to the manufacturer of the product whether to send audio from the contact or not. Apple’s first Macbook Pro computers with Mini Display port had such support only image but from 2010 models, they send also sound out of touch. As regards the HDMI, the standard audio. Neither VGA or DVI standard supports audio at all.
  • The connector is much smaller than both VGA and DVI.
  • Connector can output a small drive current in the cable for example. conducting an active converter.

Just as HDMI has DisplayPort existed in several versions. DisplayPort 1.2 was launched in 2010 and is today considered the basic version of DisplayPort. The supports transmission of up to 3840 x 2400 in 60 Hz, which is higher resolution than Ultra HD 4k. DisplayPort can also transmit 1920 x 1080 in both the 120 Hz and 144 Hz, making the interface suitable for game screens. DisplayPort 1.3 was launched in 2014 and supports the so-called 5k resolution (5120 x 2880) at 60 Hz.

DisplayPort cable can carry multiple audio signals. This means that your computer’s graphics card can be connected to a monitor that in turn connect to another monitor. To do this, the screens have both inputs and outputs for DisplayPort. The graphics card on your computer must also be able to send out the signal to all devices.

At 60 Hz can DisplayPort 1.2 drive two displays at 2560 x 1600 or four monitors at 1920 x 1200. DisplayPort 1.3 can transmit signals to either two monitors at 3840 x 2160, four displays at 2560 x 1600 or seven screens of 1920 x 1200!
