DVD Test Patterns: A Free Way to Calibrate Your TV

You do not need a professional calibrator to fix the most common picture problems. Many DVDs include hidden or menu-accessible test patterns, and a few dedicated discs exist for exactly this purpose. With one of them and twenty minutes, you can set brightness, contrast, color, and sharpness more accurately than any showroom preset. The result is a picture with more shadow detail, cleaner whites, and less artificial edge enhancement.

Which discs include useful patterns

The THX Optimizer appears on many Pixar, Disney, and Star Wars releases and is usually found in the setup menu. Dedicated discs such as Disney WOW, Avia II, and Spears and Munsil offer a more complete set of patterns and instructions. Any DVD player can display them, which makes this one of the cheapest calibration tools available. You only need the disc, the player, and the remote for your TV.

Start with brightness, not contrast

Brightness controls black level, and it is the setting most often wrong out of the box. Load the black-level pattern, which usually shows a series of dark bars and a reference patch. Turn brightness up until the darkest bar becomes visible, then back down one step so it just disappears. If you go too far, black becomes gray and the picture looks washed out; too low and shadow detail vanishes into a single black mass.

Set contrast with the white pattern

Contrast controls peak white. Use a pattern with bright steps and a reference white rectangle. Increase contrast until the brightest step stops changing, then reduce it slightly. If white clips, clouds and bright walls lose texture and take on a flat, glowing look. On modern TVs, a contrast setting between 80 and 95 is common, but trust the pattern rather than the number.

Color and tint need a blue filter

Color saturation and hue are best set with a blue filter, which some calibration discs include as a cardboard viewer. Look through it at the color bars and adjust until the blue and cyan sections blend correctly. Without a filter, you can still use skin tones as a sanity check: faces should look natural, not orange or green. Avoid the vivid preset, which exaggerates saturation and makes everything look artificial.

Sharpness should usually be low

Most TVs ship with sharpness cranked up, which adds halos around edges and amplifies film grain. Display a pattern with fine lines or text, then lower sharpness until the halos disappear. On many sets, the neutral point is zero or just above it. A softer but clean image is more accurate than a crisp image with white outlines around every object.

Know the limits

DVD patterns cannot set white balance, gamma, or color management, and they cannot compensate for a bad viewing environment. They do fix the basics that matter most. Use them in the lighting you normally watch in, and avoid changing settings late at night when your eyes adapt differently. For related adjustments, see our guide to DVD player picture settings.

Calibrate each input separately

Televisions store picture settings per input and often per picture mode. If you calibrate the DVD player while the television is set to cinema, then switch to game mode for a console, none of your work carries over. Write down the final values, including brightness, contrast, colour and sharpness, and copy them to every input you use with a disc player. A second DVD player connected by a different cable will usually need slightly different settings as well.

Recheck the patterns after any firmware update or factory reset, because manufacturers sometimes change the default processing. If the set has a store or vivid mode, avoid it entirely during calibration; those modes deliberately exaggerate contrast and colour and will make the test patterns useless.

Try it this weekend

Find the THX Optimizer on a disc you already own, or borrow a calibration DVD from a friend. Write down the before and after values, then live with the new settings for a week. Once you see shadow detail you were missing, you will not want to go back. If you use a projector, our projector setup guide covers the connection side.
