When using splicing screen products, we often encounter some situations for various reasons, such as flower screen, black screen, vertical line on the screen, etc. Although these problems will not directly lead to the scrapping of splicing screen, they will affect our normal use to a certain extent, especially in the case of monitoring, because the display of monitoring needs to be turned on 24 / 7, any negligence may allow criminals to succeed, Therefore, when encountering some simple problems, our users must learn "self" - help ", so there is no need to perform any operation. Everything depends on the after-sales service of the manufacturer.

Usually, splicing screen is the most common. If this happens, Weikang technicians suggest the user to check from the following places.

1. Graphics card driver

Most of the splicing screen is caused by the display driver. It is recommended to reinstall the driver first. If not, it can be replaced directly.

2、 Power supply

The power and time of power supply will affect the peak value of power supply to a certain extent, resulting in unstable power supply, thus affecting the display effect and blurring the picture.

3、 Connecting cable

We usually use Akihabara or lvlian brand when installing the splicing screen. We must make a comprehensive selection according to the distance of transmission. Because the quality of wire directly determines the quality of the picture, we warn users not to use wire to save costs, otherwise it will lead to many after-sales problems. If this happens, just wrap the line.

If the above three methods still can not solve the problem when the splicing screen is blurred, professional knowledge is needed to detect the hardware. Users are not recommended to disassemble the equipment by themselves.
