The H79 projector is the flagship of Optoma's Custom Series line. It features a single DarkChip3 DLP chip that outputs a 4500:1 contrast ratio at 1000 lumens, with an eight-segment color wheel. The H79's 23dB plex noise level makes it one of the quietest on the market. Just this July, Optoma introduced a less pricey version, the H78, with a 4:000:1 contrast ratio and 800 lumens of brightness.

The other crucial factor in determining the optimum screen size for a front-projection theater.com">home theater is the distance from the surface of the screen to the primary plex seating position in the theater. Assuming your system includes a video processor (line doubling, tripling, or scaling) for NTSC sources like DVD, a good rule of thumb is to be three to four times the picture height away from the surface of the screen at the primary seating position. For example, with a 72" wide screen, which has a height of 40.5" (16:9 aspect ratio, of course), the ideal seating distance would be between 121.5" (10.1') and 162" (13.5'). The idea is to sit as close as possible so that the screen subtends as large a field of view as possible, yet not so near that you can see the picture structure, whether that structure is made up of scan lines on a CRT-based projector, micromirrors on a DLP unit, or pixels on an LCD or D-ILA projector.

Begin the Dialogue Notice how your 6-year-old can always tell who got the most cookies? That's a developmental milestone. His heightened sense of fairness makes this an ideal time to enhance his cultural knowledge by focusing on a topic he's interested in. Begin a historical dialogue with your sports enthusiast about Jackie Robinson, for example. Or captivate your music lover by sharing Marian Anderson's life story. You should explain that these people faced great odds and were mistreated simply for the color of their skin. Yet they never gave up. Tell your child: These great folks are a part of our heritage. Their fighting spirit is inside you, and there's nothing you can't do--no matter what people may say or do to tear you down.
