An Expert's Opinion About DisplayPort Interfaces

Greg Pepin, L-com Inc.

We consulted L-com Product Manager of Video Products, Greg Pepin, for information on the latest video interface type - DisplayPort.

Here is what he shared with us:


Question: What is DisplayPort?

Answer:
DisplayPort is a fully digital A/V interface that has been ratified by VESA (Video Electronics Standards Association) as an improvement over older computer monitor interfaces like SVGA and DVI.

As a voting member of VESA, I've been able to see its advancements and have experienced its amazing HD content.

DisplayPort High Definition Audio/Video Cables

DisplayPort cables offer a number of advantages over the older types, including:

  • All digital transmission. Crisp images and vibrant, deep colors rendered by the video source are displayed with pixel-for-pixel perfection on the screen.
  • Built-in audio. With DisplayPort cables, you don't need a separate audio line.
  • Easier locking mechanisms. Unlike the old screws in the flange, DisplayPort cables easily lock and unlock with the push of a tab on top and do not disconnect like HDMI connectors.

Question: How is DisplayPort different from HDMI?

Answer:

HDMI (High-Definition Multimedia Interface) was designed as a home-theater type of interface. DisplayPort is intended for computer/monitor applications. Both are similar and capable of achieving 1080p.

Question: What if I already have a DVI-I or HDMI video card and need to convert to DisplayPort?

Answer:

DisplayPort to DVI and HDMI AdaptersOne of the truly great advantages of DisplayPort is that it easily converts to other digital video formats. Simple interface adapters make the connection. Keep in mind that when you have analog signals, such as DVI-A or SVGA you must use a media conversion box to convert analog signals to digital signals.
