This screen selects the type of genlock source and then allows fine adjustment of the
horizontal and vertical timing, and audio delay—relative to the source selected. There
are two ways to enter a value:
• Click and drag the slider.
• Click on the numeric value above the slider, enter a new value and press Enter to
commit the changed value.

Horizontal Output Timing, pixels (6.2)—This slider adjusts horizontal output timing
relative to the reference video already selected. When adjusting the horizontal
timing (H), this value specifies a number of pixels to offset, from zero to full line
width.
Horizontal Output Fine Timing—Further adjusts the horizontal analog output timing
(only) in finer increments than 6.2 (above)—in this case by sub-pixels. Each
adjustment of the control, from 0 to 127 adjusts the timing by 1/128th of a pixel.
Note: This fine timing control only affects the analog outputs.
Vertical Output Timing, lines (6.3)—This slider adjusts vertical output timing relative to
the reference video already selected. When adjusting the vertical timing (V), this
value specifies a number of lines to offset, moving the screen up to a half a frame up
or down.
