A display adapter adapts a display, such as a laptop display, to a projector display panel for use with an overhead projector. The laptop display is detached from a laptop CPU and physically and electronically connected to the adapter. The display adapter has a parallel conductor and electronic interfacing circuitry to interface the display with the computer CPU via the parallel port of the laptop. The adapter has an enclosure with a central body and two extendible sleeves slidably mounted to the body to move between an expanded position and a collapsed position. In the expanded position, the sleeves project outward from the body in opposing directions. In the collapsed position, the sleeves are slid inward relative to the body toward each other to an abutting relationship. The enclosure also has two support arms movably mounted to the first and second sleeves, respectively, to move between an opened position and a closed position. When the adapter is arranged with the sleeves in their expanded position and the arms in their opened position, the display mounts to the adapter and is supported horizontally by the support arms a safe distance from the projector light surface to prevent overheating. The extended sleeves cover one entire side area of the projector light surface adjacent to the display to block all peripheral bright spots left uncovered by the display. The adapter body has a recess sized to hold a remote control handset, such as an IR device. When the sleeves are extended to the expanded position, the recess is exposed to permit removal and replacement of the IR device. An IR port is formed in the body and exposed when the sleeves are extended to receive IR signals from the IR device.
