Teach you six strokes to solve Character LCD Modules splicing screen Huaping

The first one: Check the LCD splicing screen and graphics card connection is loose. Poor contact will result in a " clutter ", " noise " is the most common form of Huaping phenomenon .
The second measure : OLED Display Module Check graphics card overclocked . If excessive overclocking graphics cards , usually irregular , intermittent stripes. At this time , it should be appropriate to reduce the overclock . Note , first of all to reduce the memory frequency .
The third measure : Check the graphics quality . If after replacing graphics Huaping problems , and in the use of the first and second trick did not work , the card should be checked against electromagnetic interference and electromagnetic shielding whether the quality of clearance. Specific approach is: some of the parts that may cause electromagnetic interference as far away from graphics card installed ( such as hard disk ) , look Huaping disappears. If it is determined that the electromagnetic shielding function graphics , but off , replace the video card, or home-made shield .
Fourth trick : Check the LCD splicing screen resolution or refresh rate is set too high. LCD splicing screen resolution is generally lower than CRT monitors , if more than the manufacturer's recommended best resolution , there may Huaping phenomenon.
Fifth move : check if you have an incompatible graphics card driver. This is generally easy to ignore , because the graphics driver updates faster and faster ( especially NVIDIA graphics card ) , some users are always eager to install the latest version of the driver . In fact , some of the latest test version of the driver either , either graphics or game for a specialized version optimized for the use of such drives can sometimes lead to the emergence of Huaping . Therefore , it is recommended that you try to use Microsoft-certified drivers , the best use of graphics drivers provided by the manufacturer .
Sixth trick : If you use more than five strokes later, still can not solve the problem , there may splicing lcm module quality problems. In this case, replace the other monitor to be tested.
