The most likely cause for an LCD video display to show incorrect colors is related to incorrect cable connections. When the cables that connect the video source to the display are not properly connected, it can lead to poor signal transmission or incomplete data being sent to the display. This can manifest as distorted colors because the display may not receive the full spectrum of color signals needed for accurate image reproduction. Misaligned or damaged connectors can interfere with how colors are interpreted by the LCD panel, resulting in an incorrect display of colors.

While other factors can contribute to display issues, the specific nature of incorrect cable connections directly affects how colors are transmitted from the source to the display, making it a primary suspect in cases of color distortion. For example, defective power supplies might lead to a display not functioning at all rather than simply showing incorrect colors, and faulty display drivers typically result in broader issues with the image quality or functionality rather than isolated color inaccuracies. Incorrect resolution settings may alter the overall sharpness or size of the image but are less likely to directly cause incorrect color reproduction as compared to issues with the signal pathway itself.
