A method of controlling a liquid crystal display monitor (2) is disclosed. The monitor has a liquid crystal display panel (4) having a plurality of pixels, a digital to analogue converter (30) for inputting image data to the display panel, and a backlight unit (20) having discharge lamps (22). A controller (26) determines whether an average brightness of an image is above a predetermined threshold value and sets the backlight unit (20) to a lower luminance setting in response to determination that said average brightness is above said threshold value to avoid discomfort to a user viewing the monitor.
