A display strut adjusting structure is located on a base seat of a display, comprises an altitude adjusting device and an angle adjusting device. An arc-shaped suppressing plate is located on a sliding plate of the altitude adjusting device, which can push the torsion member of an outer frame component with stability thus enhance the smoothness of the altitude adjusting operation. A braking bar at the end of the outer frame component restricts rotation, and allows strengthening of the stability of the adjusted angle between the display strut adjusting structure and the base seat. A concave ring is designed on the braking bar, when depressed the braking bar causes the concave ring to align with the pivot end, the outer frame component will rotate through the concave ring in relation to the pivot end, thus, adjusting the angle of the display strut adjusting structure and the base seat.
