How to deal with the blurred screen problem of the stretched LCD bar screen? (15/LCD bar screen)

With the rapid development of science and technology, high-definition display products represented by liquid crystal display technology are gradually applied in various fields of society and play a pivotal role.

So about the stretched LCD bar screen, how to deal with the blurred screen? What should I do if the LCD module is blurred? Since many engineers first contacted or developed and used liquid crystal modules (LCD), occasionally the problem of LCD module blurring occurred. In response to such problems, Kesy Tech?has summarized the following experience for you guys?to check, as follows:

First, check whether the connection between the LCD?strip?screen and the video card is loose. Poor contact results in a "messy" and "mottled" screen, which is the most common phenomenon.

Second, check if an incompatible graphics driver is installed. This situation is generally easy to overlook, because graphics card drivers are updated faster and faster (especially NVIDIA graphics cards), and some users are eager to install the latest version of the driver. In fact, some of the latest drivers are either beta versions or versions optimized for specific graphics cards or games, and using these drivers can sometimes result in a blurred screen. Therefore, it is recommended that you try to use Microsoft-certified drivers, preferably the ones provided by the graphics card manufacturer.

Third, check the quality of the video card. If there is an issue with the display screen after replacing the graphics card, after the first and second movement fails, 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 a hard disk), and then see if the blurred screen disappears. If it is determined that the electromagnetic shielding function of the video card is not closed, the video card or self-made shielding cover should be replaced.

Fourth, check whether the graphics card is overclocked. If the graphics card is overclocked, there will generally be irregular and intermittent horizontal stripes. At this moment, the overclocking fluctuation should be reduced appropriately Please note that the first step is to reduce the video storage frequency.

Fifth, check whether the resolution or refresh rate of the bar LCD screen is set too high. The resolution of LCD screens is mostly lower than that of cathode ray tube displays. If the resolution exceeds the optimal resolution recommended by the manufacturer, the screen may appear blurry.

Sixth, if the problem cannot be solved after using the above five steps, the quality of the strip LCD screen may be affected. At this point, please try another screen to test.

At present, the stretched?LCD?strip?screen has various sizes, clear displays, and rich functions. It has been widely used in retail, transportation, banking, enterprises, and other industries. I hope the above sharing will be helpful to you guys.
