Ok, you've gone out and bought a brand spanking new plasma Tv, but how do you make sure that you're getting the best photograph out of it? To do that you need to adjust the photograph settings on your plasma Tv, otherwise known as "plasma calibration" in the Av industry.
Before you start, you should know that the best calibration for your plasma Tv will depend on your source material (i.e. What you're watching), your input expedient (e.g. Dvd player or satellite box) and the estimate of ambient light in your home environment... Among other things. You should also be aware that your plasma Tv needs to be run in for at least 200 hours to allow the phosphors to stabilize, or else you will have to repeat your plasma Tv calibration in the future.

You may not own a plasma Tv calibration Dvd, so this description will try to walk you straight through the steps using facilely available material. Remember to use the best available relationship to connect your input expedient to your plasma Tv. In descending order, the cleanest signal (and hence best photograph quality) can be obtained via: Hdmi = Dvi > Vga = component > Scart (Rgb) > S-Video > Composite.
1. Adjust Brightness. This unmistakably determines the black level on your plasma Tv: too high a setting and black will look gray; too low and dark grays are swallowed into blackness. To set brightness to its proper level, naturally play a Dvd with lots of black scenes (e.g. Opportunity scene from Star Wars). Now crank your brightness up until the black on your plasma Tv look gray, then gradually dial your brightness down until the black in the movie Just matches the black on the black bars on top and bottom of the movie.
2. Adjust Contrast. This determines the white level and is responsible for how much light your plasma Tv unmistakably emits. To set distinction correctly, play a Dvd scene containing a shiny bald head/forehead (e.g. The Fifth Element). Now increase distinction until the bald patch is glaringly hurting your eyes, and then tone it down until you're satisfied that you can see all the information within the white.
3. Adjust Sharpness. For most poorly-encoded source material you want to use this to heighten the edges, but if done excessively this will introduce haloing and ringing around edges. It's best to bring up a "User Menu" (from your Dvd, satellite box, etc) to adjust sharpness: increase it until lots of ringing artifacts occur around the edges of the words, then decrease it until the ringing just disappears.
4. Adjust Color. Color can whether be too saturated or too dull... whether way the photograph will not look right, with the most noticeable errors found in skin tones and green foliage. As a rough guide, you can use a Dvd scene with a hand and tinker with the color until the color matches that of your own hand.
What I've described above is 4 basic steps for plasma calibration using only what's available to you. If you wish to strive for more accuracy you can get a Hdtv calibration Dvd, but you'll need to know which one to buy and how to use it to calibrate plasma Tv because the majority of them are still catered for the Crt market.
