Contrast

Television Contrast Ratio

Contrast basically means how much white is in the picture on your television screen. If you have a high level of contrast, the white objects likely aren’t visible. But if you have a low level of contrast, your dark objects likely aren’t visible. When you’re calibrating the contrast on your television screen, you should consider using a calibration disc to help you out.

Calibration discs typically feature a screen that’s half black and half white. On the one side of the screen is a vertical line that is black in the white section of the screen and white in the black section. A contrast level that is too high makes the line bend, as the television monitor has trouble holding the white level.

When you’re adjusting the contrast, you should also check out the sharpness controls on your television. Make sure that your sharpness control is turned off or is at its lowest possible setting before attempting to gain proper contrast level. When your contrast levels are too high, blooming occurs. Blooming is a condition in which white areas in the picture begin to expand as the contrast is turned up. This is caused by your television monitor not being able to control the white level at that setting. The proper white level should be found before the point that blooming begins to occur.

You should also know that brightness and contrast affect each other as well. The calibration discs for your contrast are great at helping you understand the settings and how they affect each other. Before you jump into getting the settings correct, it’s a great idea to sit down and carefully watch and listen to the description of the test, what to look for, and observe as the disc simulates changing the setting.

When you adjust the brightness on your television, you’ll want to check the amount of light you have in the room coming from windows and lighting fixtures. When you’re setting up the contrast and brightness settings on your television, make sure your room as the typical amount of ambient light. A typical amount is the amount of light you would have in the room as you normally watch television. If you typically watch television with the shades drawn and the lights off, then those are the room conditions you should use when performing video calibrations.
