To choose the right one LCD TV for you
ByHow to choose the size of my TV?
Here are the most important criterion in choosing your TV. Not an inveterate viewer but you are attracted by the giants of the market? Do not throw our heads down on 52 inches of your dreams. To know what you can leave groped, you need to do some math! The era of having to place the television picture tube more than 3 meters to the couch to get a more fluid!
Thanks to high definition, closer to the TV without fear for the quality of the images or visual fatigue. Maintain a certain distance but it is advisable to take advantage of the 16 / 9 format on your TV screen. The ideal distance between you and the HD screen is proportional to its height and its technology.
So with an HD Ready 42-inch (107 cm), you’ll be at about 2.5 m away from the screen. Conversely, with a Full HD LCD screen the same size, you can place the sofa just 1.6 meters away! Then calculates a distance equal to 4 times the height of the screen to an HD Ready and 3 times for a Full HD.
The HD for everyone
Just heard of it everywhere! However, the difference between HD Ready and Full HD not you just clear. HD technology is divided into two certificates: HD Ready and Full HD picture resolutions that have very different. A TV HD Ready with a resolution of 1,280 x 720, has at least 1 million pixels and a Full HD with a resolution of 1980 x 1080, it offers twice as much.
As we have seen, this difference is not fundamental to your choice will be based rather on audio and video accessories available and their compatibility with the HD technology. A TV LCD HD Ready tends to fit the standard image in its resolution that is to say to make her go from 720 x 576 pixels to 1,280 x 720 pixels, a process that affects, of course, the quality of the images. If, therefore, a Full HD TV has to make a standard image in a resolution even higher (from 720 x 576 pixels to 1980 x 1080 pixels) image quality will be even more damaged. Therefore, contrary to what one might think, Full HD technology can be fully exploited only if you have HD compatible accessories (a Home Cinema, a video game console, an HD tuner, a Blu-Ray, etc …).
If you’re thinking just now entering the world of high definition, choose an LCD TV HD Ready, able to offer you a better rendering of images “standard” (DVD, Freeview, satellite).
Reactivity of LCD TV
Nowadays, most LCD televisions has a active matrix or TFT, capable of offering millions of colors and even billions of colors, response time and a more fluid and fast. However, the presence of static images (the logo of a channel or a continuous strip of information) are likely to “burn” of pixels. To resolve this problem, some LCD TVs are equipped with a system called “auto pixel shift” that limits the number of pixels “dead”.
Improve the performance of your TV
In this section, we will not get more than size or definition of your LCD television, but rather how to use its settings to increase your comfort. To get more natural looking images, you should choose a screen contrast and brightness by moderate non glare. Manufacturers tend to swell these values by providing impressive dynamic contrast ratio. Directs your research rather than on the quality of static contrast, a figure that can determine how your TV is able to distinguish between dark gray and black.
The average is between 1:1000 and 1:6000, depending on the size of the screen. In most cases, for each type of program, there are ways of improving the image suitable. Just a button on the remote control to create the right atmosphere, but you can always choose to adjust the image yourself.
