With the development of the high-tech era, the use of LCD splicing screen displays has become increasingly popular. However, due to users' lack of understanding of the internal structure of LCD splicing wall large screens, there are also many problems that may occur during the use of LCD splicing walls. One of the common problems is that the black color on the left and right sides of the monitor screen cannot be adjusted properly. How to solve the problem of black color adjustment on the left and right sides of the LCD splicing wall display screen?

Usually only 5 tricks are needed, and Shenzhen LCD splicing screen manufacturer Jintong Display teaches you how to solve the problem of black screens on the left and right sides of LCD splicing screens:

Step 1: Check if the graphics card is overclocking excessively. If the graphics card is excessively overclocked, irregular and intermittent horizontal stripes will generally appear. At this point, the overclocking amplitude should be appropriately reduced. Note that the first step is to reduce the video memory frequency.

Step 2: Check if the connection between the LCD splicing screen and the graphics card is loose. Poor contact can lead to the most common phenomenon of "clutter" and "dots" like flower screens.

Step 3: Check if the resolution or refresh rate of the LCD splicing screen is set too high. The resolution of LCD splicing screens is generally lower than that of displays. If it exceeds the recommended optimal resolution by splicing screen manufacturers, there may be screen distortion.

Step 4: Check if incompatible graphics card drivers are installed. This situation is generally overlooked because the update speed of graphics card drivers is getting faster and faster (especially NVIDIA graphics cards), and some users are always eager to install the latest version of drivers. In fact, some of the latest drivers are either test versions or optimized versions for a specific graphics card or game, and using such drivers may sometimes lead to screen flickering. So, it is recommended that everyone try to use Microsoft certified drivers, preferably those provided by graphics card splicing manufacturers.

Step 5: Check the quality of the graphics card. If there is a problem of screen distortion after replacing the graphics card, and the previous methods do not work, then the anti electromagnetic interference and electromagnetic shielding quality of the graphics card should be checked to see if they are up to standard. The specific method is to install some components that may cause electromagnetic interference as far away from the graphics card as possible (such as a hard drive), and then check if the splash screen disappears. If it is determined that the electromagnetic shielding function of the graphics card is not up to standard, the graphics card should be replaced or a self-made shielding cover should be used.
