Contrast ratio is a requirement that people seem more interested in finding a new HDTV. The contrast ratio is the difference between the darkest dark scene and the brightest light in the scene could see the screen. A beautiful high contrast ratio at 8000 to 1 or higher, give a picture of a real life and feel sharper. The exact ratio depends greatly on the route chosen by the manufacturer to measure to make the maximization of the contrast with the choice ofHDTV> another is a dubious plan. But there is one sure way to improve things, regardless of the TV data:
The key is to "trick" your eyes a bit '. Your iris (the "opening" of the eye) constrict in bright light and dilate in the dark light, is not it? If your TV room is completely dark, eyes are enlarged and sensitive to small amounts of light, then turn down the brightness on the screen to the dark areas appear completely blacks. This also appliesreduces the brightness of the lights so that the apparent contrast ratio.
If you are a weak light source, location as a small lamp behind the TV in an otherwise dark room, your iris contract a bit 'and allow you to turn the brightness a bit'. You can still see black as pure black, and is more brightness in bright scenes are so apparent and the contrast makes the image look better. Stifling your iris will also increase the sharpnessYour vision, such as stopping down the lens of the camera lens increases sharpness and depth of field. And the dark, the scattered light would not cause glare on the screen as a direct light or head.
Of course, also helps to find out if a particular HDTV really so good, contrast ratio that the producer said one. One way to discover this is the view wishlist view HDTV, customers compare the current one.
