Six solutions for LCD screens
During the operation of the monitor, it is easy to appear the phenomenon of LCD screen splicing. In the end how to solve this annoying problem?
The first move: Check whether the connection between the LCD splicing screen and the graphics card is loose. Poor contact can cause "clutter" or "noise"-like flower screens to be the most common phenomenon.
The second measure: Check whether the video card is overclocked. If the video card is over-used excessively, irregular and intermittent stripes will appear. At this time, the frequency of overclocking should be appropriately reduced. Note that we must first reduce the memory frequency.
The third measure: Check the quality of the video card. If the video card appears after the replacement of the video card, and after the first and second strokes fail to work, check whether the anti-electromagnetic interference (EMI) and the electromagnetic shielding quality of the video card are over. 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 should be replaced, or the shielding mask should be made.
The fourth measure: Check whether the resolution or refresh rate of the LCD splicing screen is set too high. The resolution of the LCD splicing screen is generally lower than that of the CRT monitor. If the resolution exceeds the best resolution recommended by the manufacturer, the phenomenon of flowering may occur.
The fifth measure: Check if an incompatible graphics card driver is installed. This kind of situation is generally easy to overlook, because the graphics card driver is updated faster and faster (especially NVIDIA graphics cards), 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. Using such drivers can sometimes lead to the appearance of flower screens. Therefore, it is recommended that you use Microsoft-certified drivers as much as possible. It is best to use drivers provided by the graphics card manufacturers.
The sixth move: If you can't solve the problem after using the above five strokes, you may have problems with the quality of the LCD splicing screen. At this point, replace the other monitor for testing.
