Apple Studio Display 15-inch LCD: Vertical Gray Bar With Monitors & Sound

I have an Apple Studio Display 15-inch LCD and when I adjust the horizontal position to the maximum position, either to the right or to the left, through the Monitors and Sound control panel, I notice a 1/4 inch vertical gray bar going down the edge of the screen. Is this normal?

Yes, when you move the position of the display (raster) all the way to the left or right of the screen, you are displaying an area of the display which is outside of the usable area. This area can be various colors other than gray.

To correct this problem, adjust the screen position, through the Monitors and Sounds control panel, so that the raster is centered in the usable area of the display.
