  "textContent": "The present invention relates to a method for operating a high-resolution projection headlight for a motor vehicle. The high-resolution projection headlight has an active LED pixel matrix light source which comprises an LED matrix monolithically integrated into a semiconductor chip with a plurality of light diode-based pixels and a driver circuit for separately controlling each individual pixel within the LED matrix. A current digital image of a sequence of images is continuously rasterized by means of a graphical controller from graphical data with at least one graphical object () and is provided for image reproduction with the projection headlight. A value for a thermal loading of the LED pixel matrix light source is continuously determined. During the rasterizing of a current digital image, surface areas () of the graphical objects () to be projected are at least partially masked with a masking () and modulated, provided that the value for thermal loading exceeds a limit value. The invention also relates to a corresponding projection headlight system for a motor vehicle.",
