The TV picture is not good? From these two angles to explore

The poor TV picture effect may be caused by the input signal or the quality of the TV itself. This paper will discuss this problem from these two angles and provide corresponding solutions.

Input signal problem

When receiving a signal through an AV line, the picture effect may be poor due to the loss of line quality or transmission. In addition, the quality of the film source is also an important factor, and a low-quality film source naturally cannot present a high-quality picture.

The quality problem of the TV set itself

A simple detection method is to download a high-definition film source (at least 720P) with a USB flash drive, and then play it on TV. So you can judge whether it's the input signal or the quality of the TV itself.

Comprehensive consideration, take corresponding measures.

Considering the above factors comprehensively, we can understand the problem more comprehensively and take corresponding measures to improve the picture effect. For example, replace high-quality AV cable, improve the quality of film source, and replace TV set.
