1. Check whether the video card is overclocked. If the graphics card is over-used, there will be irregular and intermittent horizontal stripes. At this time, the overclocking amplitude should be reduced appropriately. Note that the frequency of video memory should be reduced first.
2. Check whether the connection between LCD splicing screen and graphics card is loose. It is the most common phenomenon that poor contact will lead to "clutter" and "speckled" flower screen.
3. Check whether the resolution or refresh rate of LCD splicing screen is set too high. The resolution of LCD splicing screen is generally lower than that of display. If it exceeds the best resolution recommended by splicing screen manufacturers, there may be a phenomenon of flower screen.
4: Check whether an incompatible graphics driver is installed. This situation is generally easy to be ignored, because the update speed of graphics card drivers is getting faster and faster (especially NVIDIA graphics cards), and some users can't wait to install the latest version of drivers. In fact, some of the latest drivers are either beta versions or optimized versions for a special graphics card or game, and the use of such drivers may sometimes lead to the emergence of a screen. Therefore, it is recommended that you use drivers certified by Microsoft as much as possible, and it is best to use drivers provided by graphics card splicing screen manufacturers.
5. Check the quality of the graphics card. If there is a problem of screen display after replacing the graphics card, if the previous measures fail, you should check whether the anti-electromagnetic interference and electromagnetic shielding quality of the graphics card pass the standard. The specific method is: install some components that may cause electromagnetic interference as far as possible away from the graphics card (such as hard disk), and then see if the 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 made.
