The Output menu is used to select gamma correction and to turn frame lock on/off. Gamma correction can be used with displays that do not show the correct light level within a certain range. Proper setup requires test patterns and test equipment normally used by calibration professionals. Gamma correction curves other than exponential (default 100) must be made through a computer – see section 3.8. The default gamma selection is Gamma Corr Off.

Frame Lock

Synchronizes the output refresh rate to the input (default Off). When Auto is selected, the refresh rate will synchronize, overriding the setting in menu 8, unless the nature of the input prevents this lock. Frame Lock can be useful when the display accepts video-based refresh rates (50 Hz in PAL regions or 60 Hz in NTSC regions) and film-based rates (24, 48, or 72 Hz) thus making motion smoother when watching both types.

To use Frame Lock, set the output in menu 8 to 720p/24 or 1080p/24, or use the Live Video Settings Editor to load 720p/48, 720p/72, or 1080p/48. Set Frame Lock to Auto for all sources that you want to come out at the same frame rate as the input (or better yet program source layers, for example DVD1 and DVD2, such that Frame Lock is active in one layer and off in another – see section 3.5).

When playing a 50 or 60 Hz source that originated from 24 frame-per-second film, turn Frame Lock off (or change source layer) – the output refresh rate will change back to 24/48/72 Hz.

Test patterns from the following menu can be used to adjust the brightness, contrast, and color on your display by eye. Since they are digitally generated, these patterns can be more accurate than those played from a disc (some of which contain errors). Adjustments in previous menus are bypassed.
