Important if several people to watch TV at the same time and the spatial relations are so stored that not all viewers can head-on look on the screen. Image construction time (response time) the pixel response time is measured in milliseconds. It specifies the amount of time in which the liquid crystal in LCD cells to align, to let the light of the background lighting or to disable. For faster panning may occur again in LCD technology to short-term fray of individual parts of the image, a problem that occurs sometimes when running quickly across the screen text like the stock ticker or film credits. A short response time is therefore desirable. 8 ms are a good value, about 20 MS will be tedious, the majority of equipment currently has response time of 12 to 16 ms. The contrast contrast ratio describes the lighting ratio of black and white pixels. The higher the value the better.
A high contrast value ensures brilliant and colorful images. Read more here: Dr. Paul Craig Roberts. The contrast ratio of plasma televisions is well above the by CRT equipment. However, the contrast is not necessarily an indicator that can be used for direct comparison of models. The discovery of the contrast ratio is not standardized, so the calculation is whether the manufacturer. This strong differences occur, because E.g. a manufacturer determines the contrast ratio in daylight conditions and the other in abgedunkeltem space. Sound stereo sound is now standard.
Moreover, offer some models of Dolby Digital. Who makes however high demands on the sound not passes system to a home theater. Just when LCD TVs must, due to the construction, compromising the speaker laugh made are. Deep bass is hardly possible. Integrated surround solutions (virtual sound) drive up the price of TV unnecessarily in the height, and offer no real alternative to the home theater. In addition to the speakers, you will need a decoder, which can accordingly break down the tone and distribute.
