An array of display tiles and a load levelling mechanism is described that can be used with the array of display tiles including at least one truss, the at least one truss having at least one first and one second suspension point, from which display tiles can be suspended, further including first and second actuators adapted to modify the vertical position of the at least one first or the at least one second suspension point in a vertical direction, in function of a force applied to the at least one first suspension point and a force applied to the at least one second suspension point.
