There are many factors that users consider when choosing a TV. The viewing distance of the TV is also one of the key factors. Watching TVs of different sizes and different resolutions will have different viewing distances. If the size of the purchased TV is too large or too small to be placed in an indoor environment where the viewing distance is relatively fixed, the television viewing effect and the user's viewing experience will be greatly affected. How is the best viewing distance calculated?
For many families, television is placed in the home and the viewing distance is fixed. In fact, the TV size needs to be selected based on the viewing distance. But on the other hand, watching the same TV at different distances will have different effects. This is because the limitation of human eye structure will be affected by factors such as visual angle and visual acuity, and it cannot simply restrict the viewing distance.
In addition to TV screen size and the physiological structure of the human eye, TV display resolution is also an important indicator. This resolution refers not to the physical resolution of the LCD TV screen but to the actual display resolution of the screen display. For example, when a 1080p TV shows 1080p video and displays 720p video, we will have different feelings when watching at the same distance.
Appropriate viewing distance allows users to get the best experience The current best viewing distance calculation formula in the market is:
Best viewing distance = screen height ÷ vertical resolution 3400
If it is a 50-inch TV with 1080p resolution, then according to the formula, it is known that the best viewing distance is 1.96 meters.
Seeing here, it is estimated that another friend will ask, the best viewing distance for many 50-inch TVs on the market is much longer than the calculated distance. Does that mean that manufacturers have problems with product parameters? In fact, even if we bought a 1080p TV home, more time is watching cable TV. And cable TV often falls short of the 1080p standard. So according to the actual display resolution, we need to recalculate the optimal viewing distance.
If it is 720p resolution, after calculation, the viewing distance will become 2.94 meters, and if it is the old 480p level screen, the best viewing distance will be extended to 4.41 meters. That is, as the screen resolution decreases, the user needs to increase the viewing distance in order to be able to see a clear picture. So manufacturers generally choose an intermediate value as the best viewing distance for TV.
Therefore, the best viewing distance parameter provided by the manufacturer is not absolute, and the user can only use it as a reference when purchasing. Instead of referring to official parameters, it's better to experience the feeling of watching TV at different distances and then choose the TV size you want.
