Solve the problem of black screen left and right of LED screen

Step 1: Check whether the LED screen graphics card is overclocked. If the graphics card is overclocked, irregular, intermittent stripes will generally appear. At this time, the overclocking amplitude should be appropriately reduced. Note that the first thing to do is to lower the memory frequency.

Step 2: Check whether the connection between the LED screen and the graphics card is loose. Poor contact will lead to the appearance of "clutter" and "clutter"-shaped screens. It is a relatively common phenomenon.

Step 3: Check if the resolution or refresh rate of the LED screen is set too high. The resolution of the LCD splicing screen is generally lower than that of the monitor. If it exceeds the better resolution recommended by the splicing screen manufacturer, the phenomenon of the screen may appear.

Step 4: Check if an incompatible graphics card driver is installed. This situation is generally overlooked, because graphics card drivers are updated faster and faster (especially NVIDIA graphics cards), and some users are always eager to install the new version of the driver. In fact, some new drivers are either beta or optimized for a particular graphics card or game, and using these drivers can sometimes lead to blurry screens. Therefore, it is recommended that you try to use the driver certified by Microsoft, and it is recommended to use the driver provided by the LED screen manufacturer.

Step 5: Check the quality of the graphics card. If there is a problem of blurred screen after replacing the graphics card, if the previous tricks fail to work, you should check whether the anti-electromagnetic interference and electromagnetic shielding quality of the graphics card pass the test. The specific method is: install some components that may generate electromagnetic interference as far as possible from the graphics card (such as hard disk), and then check whether the LED screen blurred screen disappears. If it is determined that the electromagnetic shielding function of the graphics card is not enough, the graphics card should be replaced, or a self-made shielding cover should be used. Enbon
