Is the appliance screen an LCD panel?
While using the appliance, several pixel spots (red, green, blue, white, black) may appear on the screen. This phenomenon can be seen due to the characteristics of the LCD panel and has nothing to do with the performance of the monitor. This is not a malfunction, so use it with confidence.
