DisplayPort
What is DisplayPort?
 It's a new digital display standard. It started hitting the market in 2008.
 It's compared very closely to HDMI because of its looks and ability to transport video and audio signals which current computer display interfaces can’t do.
 It supports both external (box-to-box) and internal (Chip- to-Chip) display connections
 is royalty free unlike its competitor HDMI. HDMI currently has a $0.04 per device royalty and charges large manufacturers have a $10,000 annual fee.
Video Interfaces
 DisplayPort can replace all of the following interfaces
- DVI (Digital Visual Interface)
- LVDS (Low-Voltage Differential Signaling)
- HDMI (High Definition Multimedia Interface)
- VGA (Video Graphics Array)
