Abstract
A system for displaying images of varying resolution (i.e., XGA, SVGA, VGA) on a pixel-addressed screen surrounds selected-resolution images with blanked rows above and below the image and blanked columns to the left and the right of the displayed image. During the vertical blanking period, switches in the vertical scanning circuit blank non-image rows above and below the image, and, during horizontal scanning, switches in the horizontal scanning circuits blank columns on the left and right of each horizontal line so that the display image is bounded by a blanked screen portion. A black signal from a black-signal generator drives each blanked pixel to frame the displayed image in black.
