I've read alot about the benefit of calibrating a plasma panel, using a DVD such as the video essentials disc. However there dosen't appear to be enough ajustment on a normal consumer panel. i.e you can adjust contrast, brightness, colour and sharpness etc, but that's about it. How would you go about ajusting the colour temperature and individually adjust the red, green and blue colours. Unless you can alter all these other settings, how can you get the picture right?
