The present invention provides a flat screen display cover for a video display unit that is mounted to a wall. In an illustrative embodiment, the cover unit includes a frame, a box-like extension located behind the frame, and a movable cover attached to a roller that is located within and supported by the extension. A motor unit located within the extension is operable to rotate the roller so that the movable cover acts to cover and uncover the display panel. A mat is disposed within the extension and supported between the movable cover and the display screen so that when the art cover is removed from in front of the video display screen, the user will not see a gap between the border of the screen and the art frame. Various size mats, or the cutting of various size openings in a mat, allow for a single-sized art frame to accommodate a variety of display screen sizes, as well as a variety of art print sizes.
