One of the best ways to tune your TV to get the best picture quality is to use any DVD with the built-in THX Optimizer. This is a set of test patterns that play through your DVD player to your TV screen to help you adjust colour, brightness and so on.
To use the THX Optimizer properly you need a special pair of THX glasses (pictured) to carry out the calibration. We're offering them for just £6 including postage and packaging on ebay (opens in new tab).
They're a great way to help you calibrate your TV's picture to perfection, and can be used in conjunction with a number of DVD discs which include the THX Optimizer: all six Star Wars tiles, Titanic, Toy Story (1 and 2) and Indiana Jones and the Last Crusade, among others.
Find out how to use the THX Optimizer and calibrate your TV in our special THX blog.
