In a device for displaying a video image with a source (44,44') emitting at least an intensity-modulated light bundle (39,39') and a deflecting device (41,4 2) for deflecting the light bundle (39,39'), for the angle-proportional scanning of Np image points in lines over an angle .alpha.p, and for the angle-proportional sca nning of the light bundle (39,39') of Nz lines of the video image over an angle .alpha.z, the source (44,44') emits two light bundles (39,39') which can be modulated independently from one another, the first light bundle (39) being modulated with the video information for the illumination of a first image point controlled by raster sca nning and the second light bundle being modulated with the video information for the illumination of a second image point, wherein the video information of the secon d image point is offset relative to the video information of the first image point by mz lines of an image and mp image points of a line, with whole numbers mz~Nz and mp~Np, and mz and/or mp~0, and an optical system (40) is provided which combines the two light bundles (39,39') at a common real or virtual point (54) situated i n front of or inside the deflecting devices in the direction of light propagation, the t wo light bundles (39,39') traveling apart proceeding from this real or virtual point (54) at a predetermined angle mz x .alpha.z/Nz in the image scanning direction and at a predetermined angle mp x .alpha.p/Np in the line scanning direction.
