Extron electronic IN1508 manual Horizontal Start and Vertical Start status indicator bars

Horizontal Start and Vertical Start status indicator bars

The input start controls adjust where the electronic scaling process takes effect. The input start and active area should be manually adjusted, if necessary, to match the input video signal, framing the active area of the input signal. If the start is set incorrectly, the switcher may add blank borders on the leading edges (top or left side) or it may crop the active area on the trailing edges (bottom or right side).

Figure 3-24 shows an image that is improperly started (as indicated by the dashed lines). If the horizontal start adjustment is set to less than the amount of actual blanking, the IN1508 starts scaling the input before the start of the active image.

This early scaling results in a blank border on the left side and cropping on the right side, and looks as if the image is shifted to the right.
