— All video scopes have a Low Pass Filter setting in the video scope option menu that filters out a signal’s noise to make the scope graphs clearer to read. While this can act as an “x-ray” to better see detail in the scope graph interiors, it can make the highlight and shadow excursions on the graph seem a bit shy of where they actually are, so it’s recommended to enable the “Extents” option of whichever scope you’re using to get an unambiguous look at the maximum excursions in your scopes. Extents draws an outline highlighting all graph excursions to show you the true level of all overshoots and undershoots in the video signal, even when the Low Pass Filter is on.

Display Qualifier Focus in Video Scope Graphs
The Display Qualifier Focus setting in the video scope option menu helps you identify which features in the video image correspond to which parts of the video scopes. With Display Qualifier Focus turned on, choosing the Qualifier mode of the Viewer and moving the eyedropper around the image draws circles around the sampled pixels as they appear in the currently visible video scope graph. If multiple video scopes are visible, each scope will have an indication of the location of the sampled pixels that’s specific to each scope.
