Firstly, check if the connection between the LCD screen and the video card is loose

      Poor contact can lead to
 

      Secondly, check if incompatible graphics drivers are installed

      This situation is generally easy to overlook, as the update speed of graphics card drivers is getting faster and faster (especially NVIDIA graphics cards), and some users urgently want to install other drivers. In fact, some drivers for sensitive words are either test versions or versions optimized for specific graphics cards or games, and using these drivers can sometimes lead to screen rendering. Therefore, it is recommended that you try using Microsoft certified drivers and drivers provided by the graphics card manufacturer.
 

      Thirdly, check the quality of the video card

      If the display screen shows problems after replacing the graphics card, and after [sensitive words] and the second movement failure, check whether the anti electromagnetic interference and electromagnetic shielding quality of the graphics card have been tested. The specific method is to install some components that may cause electromagnetic interference, try to stay away from the graphics card (such as the hard drive) as much as possible, and then see if the screen blur disappears. If it is confirmed that the electromagnetic shielding function of the video card is not closed, the video card should be replaced or a self-made shielding cover should be made.
 

      Fourth, check if the graphics card is overclocked

      If the graphics card is overclocked, it usually presents irregular and intermittent horizontal stripes. At this moment, the overclocking fluctuation should be appropriately reduced. Please note that the [sensitive word] step is to decrease the video storage frequency.
 

      Fifth, check if the resolution or refresh rate of the bar LCD screen is set too high

      The resolution of LCD screens is generally lower than that of cathode ray tube displays. If the resolution exceeds the manufacturer's recommended [sensitive word] resolution, there may be a blurred screen phenomenon.
 

     Sixth, if the problem cannot be resolved after using the above five steps, the quality of the strip LCD screen may be affected. At this moment, please replace the monitor with another one for testing.

      At present, the long strip LCD display screen has a variety of sizes, clear display, and rich functions, and has been widely used in industries such as retail, transportation, banking, and enterprises. I hope the above sharing is helpful to everyone.
