Take a look at a picture in a color junk mail or color newspaper ad, one for a discount warehouse or similar.

If you can see this effect on a Plasma HDTV set or an LCD HDTV live..

I guarantee you will remember it.

However, this is not always the fault of the panel. This can be an artifact caused by the signal, whether it is a poor quality TV transmission, DVD player or other source.

How to know for sure?

You need to ask the sales person to put on a DVD of known quality, if you can, get one to bring along yourself.

A movie that you have seen, knowing what you know now, will make it so much easier to notice if the set in question has a problem with the solarization effect.

Many forums and expert sites suggest viewing Apollo 13, but you can also use Terminator 2 or Pirates of the Caribbean which has the THX calibration utility in the menu area.

Many DVD discs available now have this handy item on the disc menu.

Just follow the instructions on the THX menu, (You can simply ignore the Blue screen section) and you will be able to calibrate your TV and that alone is worth much more than the movie cost.

You will want to look more closely at pictures on all the HDTV models you look at after you read this article.

Remember, if you can see the problem and it bothers you, leave the set in the store!

A good quality Plasma or LCD well set up (with quality input signals) can be very impressive and can be really enjoyable to watch.

Bear in mind, many people have put up with an old school CRT TV set with convergence (color alignment) errors, weird color, burnt picture tubes and contrast and brightness trouble for years.
