1. A method of operating a high-pressure gas discharge lamp in a system for time-sequential production of colors suitable for synthesis of an image to be displayed, the method comprising the steps of: superposing a lamp current with one or more first current pulses having a polarity identical to a polarity of the lamp current to be changed, wherein the lamp current is an AC current and the first current pulses are generated prior to a change in the polarity of the lamp current; and adjusting the first current pulses with regard to their amplitude and/or temporal length and/or temporal position relative to the production of the colors and/or white segments of the image, wherein the temporal position of the first current pulses is adjusted by shifting phase of the lamp current.
