At present, the mainstream size of the TV market is between 42 inches and 55 inches. However, many comrades always look for the big screen with a good attitude when they are buying. They think that the bigger the screen, the better. This seemingly reasonable idea is actually not correct. In the previous pre-purchase guide, Xiao Bian asked everyone to first consider the TV function they needed, and this time it was for everyone to consider the viewing distance. What is the viewing distance? It is the actual distance of the TV from the viewer. If the distance is too far or too close, it will have a bad influence. For example, if you look at the distance too close, it may cause visual fatigue, and the screen will have a slight graininess and become less realistic. If you look at the distance too far, the details in the picture will be lost. When you watch TV, some subtitles and other small fonts will appear unclear and other undesirable conditions, thus affecting the viewing. So how does the viewing distance count? This depends on the size of your living room. Here is a simple calculation formula: TV's best viewing distance = TV screen diagonal x 0.0635. For example, for a 55-inch TV, the calculated result is 55x0.0635=3.4925 meters and 3.5 meters. Then for a 55-inch TV user, the distance of 3.5 meters is the best viewing distance. Of course, we can also calculate the size of the TV that is suitable for the size of the TV. For example, if the viewing distance is 3 meters, then use 3 ÷ 0.0635 = 47.244 ≈ 47 inches, then you can buy 47-inch TV is most suitable. Of course, everyone does not need to be too strict in terms of size. For example, if the distance is about 2.6 meters, then 40-inch or 42-inch TVs can be selected. Attach the TV's best viewing distance table, and everyone can choose the TV size based on this table.
