This should be done when the LCD splices the wall screen

With the continuous expansion of LCD panel market, LCD panel as an electronic product, even an industrial product, can not avoid some small problems. When it comes to LCD panel mosaic, what should customers do first? Cardiff suggests that you should first consult the LCD panel manufacturer you purchased, and then follow the prompts to carry out the following operations.

1: Check whether the connection between the LCD splicing wall and the video card is loose.
In general, the mosaic LCD screen is the most common phenomenon because poor contact will lead to "clutter" and "speckles".

2: Check the video card for excessive overclocking.
If the video card is used excessively, irregular and discontinuous stripes will generally appear. So at this time, if there is a mosaic LCD screen, the overclocking amplitude should be appropriately reduced. Note that the video memory frequency should be reduced first.

3: Check the quality of the video card.
If the LCD splicing screen still has the problem of blurred screen after replacing the video card, and the first and second methods fail to work, check whether the anti electromagnetic interference and electromagnetic shielding quality of the video card are qualified. The specific method is: install some parts that may cause electromagnetic interference as far away from the video card as possible (such as the hard disk) to see if the screen disappears. If it is determined that the electromagnetic shielding function of the video card is not up to standard, the video card should be replaced or the shielding cover should be self-made.

4: Check whether the resolution or refresh rate of the LCD splicing wall is set too high.

The resolution of the LCD splicing wall is generally lower than that of the CRT display. If it exceeds the best resolution recommended by the manufacturer, the LCD splicing screen may be distorted.

5: Check if incompatible graphics card drivers are installed.
This situation is easy to be ignored because the driver of the video card is updated faster and faster (especially NVIDIA video card). Some users are always eager to install the latest version of the driver. In fact, some of the latest drivers are either beta versions or optimized versions for a specific video card or game. The use of such drivers may sometimes lead to the appearance of a splash screen. Therefore, it is recommended that you try to use drivers certified by Microsoft, and it is better to use drivers provided by video card manufacturers.

Cardiff warm tips; If the problem of LCD mosaic screen still cannot be solved after using the above five methods, it may be the quality problem of LCD mosaic screen. At this time, please replace the other monitor for testing. If it still doesn't work, you can contact the corresponding LCD panel manufacturer - Shenzhen Shundarong Technology Co., Ltd
