Full HD or 1080P refers to a set of standards for high resolution video. 1080P refers to 1080 vertical lines of resolution. Many new TV's, projectors and Blu-Ray players are capable of producing this level of resolution.

This level of quality is typically as clear as most people can resolve at typical living room distances.

Typically, you need an HDMI cable that is up to standard as well as a Blu-Ray Player, TV or Projector.
