How can I reduce the LCD signal noise?
Noise on an LCD signal can be reduced with a termination resistor and capacitor that can be tuned to the cable characteristics. This will allow you to soften the edges and reduce the noise. If the screen tears sideways, there is generally a problem with noise on the horizontal sync signal causing irregular resets to the left-hand side of the screen. If you see a vertical rolling effect, it is generally noise on the vertical sync line or a missing sync signal.
