An information handling system display monitor transitions between flat and curved configurations by actuation of a shaped memory alloy wire within the display monitor housing. For example, a nickel titanium wire is heated by application of current across the wire to transition its crystalline form, thereby shortening the wire to adjust the configuration of a foldable display film, such as an OLED display film. Separate shaped memory alloy wires may be used to achieve foldable display film movement in each direction, or actuation of a shaped memory alloy wire in one direction may generate bias in a spring in the opposite direction that is released when a change in foldable display film configuration is desired.
