11Color/Tint control button (Col/Tnt) — This button selects the color and tint adjustment for the output display. The adjustment is made using the horizontal Adjust and vertical Adjust adjustment knobs. The adjustment range of color is 0 to 127, and tint is 0 to 255. See the “Image Adjustments” section in this chapter.
The Color/Tint control affects only composite video and
12Zoom control button — This button selects the
13Detail control button — This button selects the image detail (sharpness) adjustment for the output display. The adjustment is made using the horizontal Adjust and vertical Adjust knobs. The sharpness adjustment compensates for long cable runs. The horizontal Adjust knob controls the horizontal filter and the vertical Adjust knob controls the vertical filter. The adjustment range of each knob is 0 to 7. See the “Image Adjustments” section in this chapter.

Genlock and Vertical Interval Switching
For vertical interval switching (to allow clean switching between signals from several devices during the vertical blanking period of each signal), a composite sync signal can be applied at the Genlock In connector, and can also be passed to another device via the Genlock Out connector.
If the genlock connectors are used only for vertical interval switching, no horizontal or subcarrier phase adjustments are required.
Genlock setup
Genlock differs from simple vertical interval switching in that an external device (a black burst generator) generates a reference sync signal for the system, and every device that uses that signal has its output signal’s horizontal and subcarrier phases adjusted to exactly match that of the generator. This allows precise timing and full synchronization. Genlocked systems produce cleaner switches between inputs than do those without this type of synchronization.
