The black screen of the LCD splicing screen is not necessarily due to the damage of the LCD screen. Usually it may be caused by the graphics card settings, the splicing software parameter setting error, the coding dialing error of the splicing screen set-top box, the set-top box does not supply power (the power supply is broken), the driver board of the splicing screen is damaged, etc. Caused, so we have to investigate the LCD splicing screen system one by one.
The first step: Check whether the resolution or refresh rate of the LCD screen is set too high. The resolution of the LCD screen is generally lower than that of the CRT monitor. If the resolution exceeds the best resolution recommended by the manufacturer, the screen may become blurred.

Step 2: Check whether the graphics card is overclocked. If the graphics card is overclocked excessively, irregular and intermittent horizontal stripes will generally appear. At this time, the overclocking range should be appropriately reduced. Note that the first thing to do is to reduce the video memory frequency.
Step 3: Check whether the connection between the LCD screen and the graphics card is loose. Poor contact can cause "clutter" and "nozzle" shaped screens to be the most common phenomenon.
Step 4: Check the quality of the graphics card. If it is a black screen after replacing the graphics card, if the previous tricks do not work, you should check whether the graphics card's anti-electromagnetic interference and electromagnetic shielding quality is satisfactory.
Step 5: Check whether an incompatible graphics card driver is installed; it is recommended to use the driver certified by Microsoft as much as possible, preferably the driver provided by the graphics card manufacturer.
