What is the appropriate size of a TV?

Generally, the size to buy is determined based on the area of ​​your living room and viewing distance.

In fact, the relationship between size and distance is not absolute. The size of the TV is related to the distance and resolution of the video source.

At present, the TV signal sources, such as CCTV and IPTV, have basically reached 720P. For a 720P video source, taking a living room with a viewing distance of 4 meters as an example, a 65-inch or 70-inch TV is more suitable.

Notice:

The smaller the TV, the better it protects eyesight. When the video picture is moderate, the larger the screen and the higher the resolution, the more comfortable the human eye will be, and it will protect eyesight.
