How to maintain the video wall?
If you find dirt on the surface of the LCD splicing screen, you should use the correct method to remove the dirt. It is best to use soft, non-fibrous media, such as absorbent cotton, lens paper or soft cloth, etc., and then wipe it off gently with a little glass cleaner. It is forbidden to use chemical solutions such as alcohol, and no rough materials are allowed. cloth or paper, as these materials are prone to scratches. Be careful not to spray the cleaner directly onto the surface of the display screen. It can easily flow into the screen and cause a short circuit fault inside the LCD splicing screen, causing unnecessary losses.
If there is a DVI signal on the graphics card that is directly output to the digital signal of the LCD, this new display method will not cause any pixel loss. However, when displaying a picture smaller than the optimal resolution, the LCD display adopts two methods. One is centered display. For example, an LCD splicing screen with an optimal resolution of 1024×768 displays a resolution of 800×600. , it just displays the picture with the 800×600 pixels in the middle, and the surroundings are shadows. In this way, the signal resolution also corresponds one to one, so the picture is clear. The only regret is that the picture is too small; the other is The enlargement method is to expand the 800×600 picture to a resolution of 1024×768 through calculation for display. Since the signal processed by this method does not correspond to the pixels one-to-one, although the picture is large, it is relatively blurry. Either display method is not ideal, so it is recommended to use the maximum recommended resolution!
