It may appear screen tearing problem when you use LCD Screen. Base on our repair experience, we summarized the following methods that can solve most of LCD screen tearing problems ( It’s best to exclude problems according the gradual process in practice).

First: Check the connection between the LCD display and graphics is loose. It is the most common phenomenon that apppear clutter waves.

Second: Check Graphic card is overclocked. If the Graphic card is overclocked to use, they often turn up irregular and discontinuous stripes. Then ,you should appropriately reduce overclocking range. First of all is to reduce the frequency memory.

Third: Check the quality of Graphic card. If Screen Tearing comes out after you have replaced Graphic card and practised the first and second step, you should check the Graphic card of anti-electromagnetic interference and the quality of electromagnetic shielding are qualified. Put some of the components that may result in electromagnetic interference away from the Graphics card when you installing (such as hard disk), then look at whether Screen Tearing is disappear. You should replace the Graphics card or doing home-made shielding if the Graphics card’s electromagnetic shielding function is ineligible.

Fourth: Check the display resolution or refresh rate set is too high. LCD resolution is generally lower than CRT monitors, if it exceeds the manufacturer’s recommended best resolution, there may present Screen Tearing phenomenon to you .

Fifth: Check whether have installed incompatible graphics card driver. Such cases are generally easily overlooked for the pace of the graphics card driver update is increasing (in particular, NVIDIA graphics card). Some users always install the latest version of the driver. In fact, some drivers are either the latest beta version, or specific for graphics card or a game-optimized version,sometimes using such drivers may lead to the emergence of Screen Tearing. Therefore, it is recommended you to use the graphics card drivers manufacturers provide.

Sixth: If you still can not solve the problem after having used five methods above, there may be the quality problems of displays. Please replace the other display.

Knowledge on Screen Tearing
Screen tearing is a phenomenon in video where a newly rendered frame overlaps a previously rendered frame, creating a torn look as edges of objects (such as a wall or a tree) fail to line up. This occurs when the video card or the software using it begins updating the actively-displayed memory in a manner that is out of sync with the monitor’s refresh rate.

Tearing can occur with most common display technologies and video cards, and is most frequently seen on systems where horizontally-moving visuals are commonly found, such as in slow camera pans in a movie, or classic side-scrolling video games. The material being shown may also exhibit vertical stretching or shrinking, or repeated parts of images, during vertical motion, depending on the nature of the video.
