On the Source LUTs tab, you can select lookup tables (LUT) to control the display of grayscale layers; alternatively, you can select to have the layers re-enhanced automatically.
Auto re-enhance
Select this check box to apply a new visual enhancement when the layer display changes (for example, after panning or zooming).
With the check box selected, a new enhancement is computed using the currently viewed pixels each time the display changes. With a clear check box, the layer enhancement is not adjusted automatically each time the view changes.
