User interfaces are provided that allow for the display of a target element that may be used to adjust a gamma value of a display device. The target element includes three layers. A bottom static layer is alternating light and dark lines, which in one instance may be black and white lines of equal height. A gray static layer is solid gray, and overlays some or all of the bottom static layer. A progressive layer gradually changes from a fully transparent are to an opaque area, and overlays some or all of the gray static layer. Additionally, a manipulation area is provided, which may be a sliding mechanism. The user may adjust the gamma to a higher value when the fully transparent area appears lighter than the opaque area, and may adjust the gamma to a lower value when the fully transparent area appears darker than the opaque area. |
