- eDP (Embedded DisplayPort) is a standard widely used in laptops
- to drive LCD panels. This framework provides support for enabling
- these displays where supported by the video hardware.
+ This supports drivers that provide a display, such as eDP (Embedded
+ DisplayPort) and HDMI (High Definition Multimedia Interface).
+ The devices provide a simple interface to start up the display,
+ read display information and enable it.
