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

Poor contact can lead to "messy" and "mottled" screen patterns, which are the most common phenomena.

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 the latest version of other drivers. In fact, some of the latest drivers 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, preferably those 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 fails the first and second movement, check if 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 first 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 optimal resolution, there may be a screen distortion 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.
