Black Screen Solution

Solution: Check if the screen graphics card has excessive overclocking amplitude, reduce the video memory frequency appropriately, and then reduce the overclocking amplitude.

(2) The screen appears as a "jagged" flower screen

Solution: Check if the connection line between the screen and graphics card is loose. When the connection line is loose, the screen will appear blurred.

Solution: Check the resolution and refresh rate of the LCD splicing screen. If these two settings are too high, it will cause a blurred display. Refer to the manufacturer's recommended best index to set them
