So you've finally stepped up and ditched your bulky tube television for a sleek new flat-panel LCD set. Problem is, like most televisions, LCDs are preconfigured to make an impact on the sales floor of your local electronics superstore, not in your living room. These default settings are usually way too bright and garish to accurately represent real life. Here's how to properly set the basic picture controls available on most LCD sets to maximize your home-theater viewing pleasure.

Calibrate your LCD television

Before you get started with this project, we recommend that you have the following:

Calibrate your LCD television

Because most people turn down the lights to watch a movie, our recommendations are designed to deliver a better DVD picture in rooms with controlled lighting. Unless you're sitting at the minimum viewing distance for your LCD television's size (see the chart), you shouldn't watch movies in complete darkness because it can cause eyestrain. The ideal setup is to place a dim light directly behind the television and leave the rest of the room dark. You should also try to prevent any light in the room from reflecting off the LCD screen, as glare will hamper image fidelity.

Look for special "daylight" bulbs that glow at 6,500 degrees Kelvin. This is the standard color temperature that most producers use when creating movies and TV shows.

Wide-screen TV viewing distances
Your television should deliver the right-size picture for where you sit relative to the screen. Sitting closer to a smaller television means you won't have to splurge on a big screen. But if you sit too close, the picture quality will be substandard. Sit too far away, and you won't have an immersive experience.

42 inches	5.3	10.5

Calibrate your LCD television

By design, LCD sets have a bright fluorescent light behind their LCD panel. Called the backlight, this light source affects the brightness of the entire screen. Some LCDs have a dedicated backlight control. In a darkened room with carefully placed lighting, we recommend you lower this setting all the way before you begin adjusting the brightness and contrast. You can always raise it later if it proves too dim.

LCDs have smaller viewing angles compared with other TV types. You should always try to sit at eye level and directly in front of the screen when viewing and adjusting the image.

Technically called black level, an LCD's brightness control actually adjusts how dark the black sections of the picture appear. Excessive brightness can result in a two-dimensional, washed-out look with reduced color saturation. Images with brightness set too low tend to lose detail in shadows, and distinctions between dark areas disappear in pools of black.

Play a DVD that has letterboxing bars above and below the image and find a scene that has a roughly equal amount of light and dark material--preferably with some details in the shadows. Turn up the brightness control all the way, then decrease it until the letterboxing bars begin to appear as close to black as possible. If you notice a loss of shadow detail--for example, when people's eyes disappear into the depths under their brows--then you've set brightness too low. You may also have to adjust the backlight and contrast controls to recapture lost shadow detail.

Now set the contrast. High contrast can obscure details and distort lines in the image, causing eyestrain in dim rooms. Setting contrast too low robs the image of impact. Display a still image from a DVD of a white object with some visible details, such as someone wearing a white button-up shirt. Adjust the control up all the way, then reduce it until you can make out all the details in the white areas, such as the buttons and creases in the shirt.

In general, LCD sets can handle a higher contrast setting than other types of televisions. You can often set it as high as 80 percent without obscuring detail.

Tuning your color setting, or saturation, has a drastic effect on overall display quality. When there's too much color, the image looks garish and unrealistic. This distortion is most noticeable with reds, which are often accentuated or pushed by the television's color decoder. If there is too little color, the picture appears drab and muted. Setting color to zero results in a completely black-and-white image. Before you start fiddling with the color, find your LCD's color-temperature control. This important feature affects the set's entire palette of hues. Select the Warm or low option, which should come closest to the government's NTSC standard of 6,500 degrees Kelvin. If the picture looks too red for your taste, try the medium setting, though that often gives results that are way too blue.

Now find an image of someone with light, delicate skin tones, preferably a close-up of a face, on a DVD. Turn up the color control until it looks like the person has terrible sunburn, then reduce it until the skin looks natural, without too much red. If the rest of the colors look washed out, you can increase color slightly at the expense of accurate skin tones.

Generally, DVD images are best when proprietary processing modes such as autocolor, auto flesh tone, autocontrast, and noise reduction are turned off.

Calibrate your LCD television

For basic calibration, we recommend that you put the tint setting on your LCD television at the midway point. Another important control is the sharpness level. This function adds artificial edges to objects on the screen. Though the feature can sometimes help with soft cable signals, it almost always mars the already sharp image from a DVD. When watching high-quality movies, we recommend reducing the sharpness to zero unless you detect visible softening along the edges of text. (Use a DVD's menu screen to test this.)

Adjusting your LCD with the quick tips we've just mentioned will yield good results, but you can do even better by investing in a home-theater setup DVD. These store-bought discs offer tons of in-depth advice and calibration exercises for televisions and your entire home-theater setup. If you're game to devote the time these DVDs require, they're excellent tools. We especially like Sound & Vision Home Theater Tune-Up ($21.95), great for beginners looking for a quick way to tune up their systems, and Digital Video Essentials ($24.99), well suited for experienced home-theater fanatics.
