Need to pay attention to what to buy LCD Monitor

Users questions: What brand of any type is better thank you, we purchased 7,777,771 screen size LCD, the first to consider is the "face" size. For LCD monitors, its panel size is the size of the viewing area, and CRT displays that have. The same parameter specifications Monitors, LCD CRT viewing area than the larger, usually 15-inch LCD is equivalent to 17-inch CRT, 17 19-inch LCD is equivalent to CRT, while 19-inch LCD is equivalent to 21 inches CRT. Since each person's habit of using the different eye and head users The difference, which determines the purchase of the display screen size is different. If you normally used word processing, Internet, office, study, etc., 15-inch LCD monitor should be more appropriate. If you usually have a lot of games, audio and video entertainment, graphics and other purposes, 17-inch LCD Monitor Performance of the more prominent. If you usually want to use a computer to feel the DVD large, 19-inch LCD monitor can meet this need. 2, the current response time, LCD displays the largest selling point is to continually improve the response time of 25ms from the beginning to today's gray 4ms, fast speed upgrade People amazed. Response time determines the display screen shows the number of frames per second can, usually when the screen display faster than 25 frames per second, the human eye will quickly transform the image as a continuous screen. Playing DVD movies, playing games such as CS, to obtain the best results, need to speed screen display Degrees in more than 60 frames per second, response time of 16ms to meet the above requirements, that is, the smaller the response time, rapid changes in the effects shown in the picture more perfect. The mainstream of the market of LCD response time is 8ms, cost is quite high, as high as 125 per second display rate May be comparable CRT monitors. There is no requirement for the high number of consumers to say, 12ms, 16ms products is a good choice, daily learning, Internet, video entertainment, games and other requirements are fully meet. But in the face about to dispose of 25ms products, consumers should not The consideration. As for the already available and will become the future mainstream 4ms gray-scale products, as chosen in our society, if the price is higher than the price of their own hearts, consumers can first hold out. Also, note that response time is divided into Tr (rise time) and Tf (fall time) of two parts, From black to white to rose, white to black is called down, the response time is the sum of these two values. But some companies just marked the two values of a, in order to mislead the consumer, so you know at the time of purchase must be clear. 3 LCD brightness * contrast between liquid and crystal is among the substances Itself does not light, the backlight brightness determines its brightness. In general, the higher the brightness of LCD display, showing the colors more vivid, realistic effects the better. That the brightness of liquid crystal display unit cd * m2 (lm), general brightness of LCD 250cd * m 2. If the brightness is too low, the colors displayed will Pianan, look for a long time will feel very tired. Contrast is the brightness ratio, which is in the dark room, divided by a white screen brightness under the light under the black screen. So the more white light, more dark black, the higher the contrast ratio, the more clear and bright display screen, The level of the stronger sense of color. General 300:1 contrast ratio LCD display, some good can achieve 400:1, whereas the traditional CRT monitors up to 500:1. If the contrast is less than 250:1, when we look at the screen will produce fuzzy feeling. Often used for computer games or Consumers who do graphics, should select a high contrast LCD display. Large soft spot on the DVD users, high-brightness * High contrast LCD display is the most appropriate choice. Of course, is not the brightness, contrast, the higher the better for a long time watching high-brightness LCD screen, the eye is equally Fatigue, high brightness LCD monitor will cause excessive loss of the lamp, influence life. 4 As the viewing angle LCD light through the LCD to near vertical angle shot forward, and this we observe from the other point of view of the screen, it does not look like a CRT monitor can be seen as Very clear and will see significant color distortion. This is caused by the size of visual angle. Specifically, the viewing angle is divided into horizontal and vertical viewing angle viewing angle. In the choice of liquid crystal displays, it should try to select the viewing angle of the product. At present, the liquid crystal display, but basically in the 140 degree angle
