Getting the most from that big high definition screen. Bloomberg Boot Camp, a report on today's technology. Lots of people have been buying those big high definition screens as prices have tumbled. But what they see at home…doesn't always look as good as it does in the store. A company called Datacolor sells a device it calls the SpyderTV that can help you tune the settings to deliver the best picture possible. Datacolor has been making machines for analyzing color for 35 years….including the ones that help match paint colors. Mark Hunter, technical director of home theatre products, says the Spyder uses a measurement device on your TV….that plugs into a USB port on a nearby computer…

"And it measures color and luminance coming out of the display. And we ask the user to put a DVD in their DVD player and we put up test patterns and then we measure them to see what they actually look like coming out of your display. And we tell the user how to adjust their brightness and contrast and color and tint and color temperature preset. We tell them exactly where to put all those settings, put your brightness at 37 and your color at 17."

The SpyderTV can make a big difference. While the 200 dollar price may not have seemed like a big deal when most HD TVs were selling for five or ten thousand dollars….it does seem high today when many screens are selling for a thousand dollars or less. Bloomberg Boot Camp, I'm Fred Fishkin.
