A method for detecting defects when mixed colors among color channels on a liquid crystal monitor is disclosed. The disclosed method utilizes the interference of four channels of red, green, blue and white colors to check whether a detected liquid crystal monitor can normally show the mixed colors. A rectangular channel drawing is shown on a liquid crystal monitor; wherein the most upper left point, the most upper right point, the most lower left point, and the most lower right point are respectively allocated by red, green, blue, and white pixels. Each color channel then extends separately along the diagonal direction and accompanied with color intensity gradually decreasing to obtain an interference diagram that contains several arc stripes on the rectangular drawing. Accordingly, those defective pixels will be clearly indicated in the rectangular channel drawing because they are usually flashing visually. Additionally, color sensors can be employed to further analyze the channel weights of each pixel of the detected liquid crystal monitor, and the detecting information can be further illustrated by using a menu or a display window according to the display mode of a liquid crystal monitor currently used.
