Three notes when buying wide screen LCD
When deciding to buy a wide screen, consumers often wonder if this type of product is worth it to spend more money or the 16: 9 20-inch LCD screen is larger than the 4: 3 ratio.
Calculate display area
" Customer awareness of screen size is actually based on the height and width of the screen, " said Chris Connery, vice president of market research for DisplaySearch (USA). The 20-inch widescreen often feels like the product looks quite large, but in fact, it's smaller than a 20-inch 4: 3 system. In terms of the image size displayed, its area is only equivalent to a 4: 3 17-inch liquid crystal display.
" Customers can consider the number of pixels. A 20-inch 4: 3 screen and a native resolution of 1,600 x 1,200 will be about 1.92 million pixels and a 20-inch widescreen 1,680 x 1,050 will reach 1, 76 million pixels So, according to the number of pixels, the 4: 3 screen is more affordable, "Connery said.
Ability to take advantage of display space
Source: Krunker . " Of course, the pixel comment is based on the calculation of numbers and this loses the hard-to-see advantages of the widescreen, " Connery said. Wide screen space left and right allows users to monitor different types of documents when playing games in panorama mode or watching movies with 16: 9 ratio without seeing black bars located above and below.
Therefore, considering the price of pixels, the 4: 3 screen dominates, but the widescreen offers the feel that conventional screens can't.
Every inch doesn't make a difference
Users are often embarrassed when choosing a 23-inch or 24-inch screen. 24 inches means a longer product diagonal, but both have the same resolution of 1,900 x 1,200.
According to Connery, Apple's first 23-inch Cinema Display screen has a native resolution of 1,900 x 1,200, or 98.4 pixels per inch, close to 100 pixels per inch (ppi) - the ratio of normal eyes also see discrete pixels ".
Many other manufacturers quickly followed Apple and also built a 23-inch 1,900 x 1,200-pixel screen. However, a number of other companies, especially Samsung, found that the platform they were producing could be cut into 24-inch screens to market with natural resolution and constant cost. Although 24 inches will only have a ppi ratio of 94.3, the displayed image is not much different from the 23-inch screen.
