Projection screen color cast

Jitter stripes appear on the projection screen Failure phenomenon: When using the projector, it was found that the projected picture showed horizontal stripes that kept shaking. These stripes scrolled from top to bottom in a scanning pattern, and re-searching the signal for many times could not solve the problem. Later, I replaced the VGA signal cable connected to the computer. The problem remains. Continue to connect the projector and the original VGA signal cable to another PC, and the projector can work normally. Obviously, there is no problem with the VGA signal cable and the projector itself, then the problem may be due to the PC connected to it. Therefore, immediately check the display parameters of the PC, and find that the display color, resolution, and refresh rate of the computer are all within the working range allowed by the projector, and the adjustment is still invalid. problem analysis: It seems that this fault is a very difficult problem. It has already ruled out the ad
