Solution: The above situation is likely to be due to loosening of the connecting line between the LCD splicing screen and the graphics card. As long as the connecting line is firmly connected, the situation of "clutter" and "spotted" can be improved.
Common symptoms II: Irregular, intermittent stripes on the screen
The solution is to check whether the video card is overclocked. If the video card is overclocked frequently, the above situation will often occur. At this time, the overclocking amplitude should be properly reduced, but it should be noted that the memory frequency must be reduced first.
Common symptoms 3: If there is a Huaping, but the above two measures did not take effect after use
Solution: After the above situation occurs, the user must check the quality of the video card. The user can check whether the anti-electromagnetic interference and electromagnetic shielding quality of the graphics card pass. The specific method is: Place some components that may produce electromagnetic interference away from the video card installation (such as hard disk) as far as possible, and then see if the video screen disappears. If it is determined that the electromagnetic shielding function of the graphics card is off, the graphics card or the self-made shielding cover should be replaced.
There is also a way to solve the screen splash screen, that is to check whether the incompatible graphics card driver is installed. This situation is generally easy to overlook because the graphics card driver is updated faster and faster, and some users can't wait to install the latest version of the driver. In fact, some of the latest drivers are either test versions or versions that are optimized for a particular graphics card or game. Use of such drivers can sometimes cause corruption, so users should use the drivers provided by the graphics card manufacturers as much as possible.
LCD splicing screen maintenance tips:
1, intermittent rest. LCD splicing screens can easily overheat certain pixels due to prolonged work. Once it exceeds the limit, it will lead to permanent damage, and this leads to the so-called "bad point." Because the pixels of a liquid crystal splicing screen are composed of liquid crystals, when they are continuously operated at full load for more than 96 hours, they will accelerate to aging, and even burn out in severe cases. Therefore, if the user must work for a long time, it is best to intermittently allow him to rest for a while, or often to change the screen appearance at different time intervals, because it is necessary to reduce the brightness while waiting for work, or it is in the screen saver mode. The next operation for a while, this effort can not only delay the aging of the LCD screen, but also to avoid hardware damage.
2, find someone to repair. LCD splicing problems, prohibit the assembly of LCD splicing screen (especially for ordinary DIY interest is even more so), once the LCD splicing screen is not working properly can find a vendor to help solve. Since the transformer in the LCD backlighting assembly may still have a high voltage of 1000 V (albeit a micro-current) after being turned off for a certain period of time, non-professionals may cause new failures of the assembly if not handled properly.
3, reduce the collision. The LCD display screen is very fragile and delicate, and its impact resistance is poor. This is because the LCD contains many precision glass components and agile electrical components that can cause damage to the LCD screen and other related components in the event of a strong impact. So be sure to avoid strong shocks. At the same time, we must pay attention not to exert pressure on the surface of the LCD screen, such as pointing a certain part of the screen with a finger, which can easily cause an increase in the number of dead pixels.
4, properly handle the dirt. Once the surface of the LCD panel is found to be dirty, the dirt should be removed using an accurate method. The media used is preferably a soft, non-fibrous material, such as absorbent cotton, lens paper, or a soft cloth, and then wiped off with a little glass cleaner, prohibit the use of chemical solutions such as alcohol, can not use rough Cloth or paper items, because these materials are prone to scratches. Here we must remind everyone that do not directly spray the cleaning system to the surface of the screen, it is very easy to flow to the screen inside the LCD screen resulting in short-circuit failure, causing unnecessary losses.
Common Symptoms One: There are "clutter" and "noisy" phenomena on the LCD screen
