A mask assembly (46) for masking the non-active portions (24, 26) of a display screen (12) when showing a picture (14) in letterbox format has a pair of felt mask members (48, 50) that are transparent to infrared remote control signals (60) to enable receipt of the remote control signals by a remote control sensor (40) even though covered by the mask member (48, 50). The mask members are removably mounted to a display screen housing (36) by means of VELCRO-like fasteners attaching opposed end portions (76, 78) to vertical frame mounting members (66, 68) that, in turn, are semi-permanently attached to the display screen housing (36) by adhesive. The adhesive is hidden from view by the vertical frame members that are located adjacent to the sides of the display screen (12) to form a rectangular frame around the letterbox picture (14) and the vertical frame mounting members (66, 68) have an appearance like that of the mask members to produce a rectangular frame of uniform appearance without transverse mounting tabs or the like. Alternatively, the vertical frame mounting members are attached to the display screen housing (36) by a vertical loop (FIGS. 4, 5 and 86, 88, 93) surrounding the housing (36), by fasteners at the back of the housing adjacent the top (89, 91) or by means of counterweights (87), or are eliminated entirely and the mask members (48, 50) mounted to the housing (36) by means of a horizontal mounting loop (FIGS. 6, 7 and (94, 96, 98, 100).
