Solution for playing video file jaggedness under Win7

Sawtooth is a non-smooth line in the index code image that can be seen from the slash and the edge of the object. We also call it "confusing phenomenon", the phenomenon that the line is level one level (sawtooth phenomenon) is determined by the nature of the square of the pixel. As the resolution of the sensor or photo increases, the visible sawtooth becomes less and less noticeable. Since Windows 7, there has been a problem of jaggedness in playing video files. Even if you look at online video files, such as popular, UUSee, and Thunder, there are similar problems. At first, many users thought that RealPlayer, Storm Video, Thunder and other players were not compatible with Windows 7, but users later found that the problem of switching to other video players still exists.
Generally, the problem of mosaic, blur, and jaggedness in the playback of audio and video files under Windows 7 is related to the graphics card driver. For example, poor compatibility or driver mixing may cause such problems.
