A method and system of controlling a display device on a work machine having grade control

A display system and method for a work machine having grade control is disclosed. The display includes a frame, an attachment coupled to the frame, a first sensor, a second sensor, and a controller. The first sensor is configured to generate a first sensor signal indicative of a frame angle relative to a direction of gravity. The second sensor is configured to generate a second sensor signal indicative of an attachment angle relative to one of the frame and the direction of gravity. The program instructions cause a processor on the controller to receive a first sensor signal, a second sensor signal, and a target grade input; determine a cross slope and a mainfall, and control a display device to display a singular graphic of the position of the attachment relative to the target grade.
