  35. Large, High-PAR, High-Lumen Displays • DAR changed from 4 : 3 to 16 : 9 • Displays can be large • LCD screens • Digital projection • Pixel densities can be high • Color can be brilliant

  36. HD Technology

  37. Digital Versatile / Video Disk (DVD) • Replaces • CD-ROM (also supported by player) • Audio CD (also supported by player) • Laser videodisc • Offers support for 4 x 3 DAR • Maximizes HD with 16 x 9 DAR and high computer PAR
