In Figure 4, the total pixels are adjusted incorrectly. There are several ways to set the total
pixels. It is best to set the total pixels according to the input signal specifications. Otherwise, if
the input pixel clock is known, the input total pixels may be calculated using one of the methods
shown below:
•
Check the On-Screen Menu: The input horizontal scan rate, as measured by the
IN1401, may be found in the options menu under SYSTEMS INFO on page 7.
•
Multiply the input active pixels by 1.3 to approximate the input total pixels.
•
Adjust the input total pixels to minimize any faint vertical lines that may be seen
within the image, as shown below in Figure 4.
The total pixels may be adjusted to move the lines closer together or further apart. Adjust the
total pixels until the lines are furthest apart or until they are completely out of view. If one line
still remains, it may be moved out of view using the phase adjustment. The input active pixels
and total pixels are interactive. Setting one may require readjustment of the other.
1. Set input total pixels according to input signal specifications.
2. Input total pixels = input pixel clock / input horizontal scan rate.
3. Input total pixels
≈
1.3 x input active pixels.
4. Set input total pixels to minimize faint vertical lines (see Figure 4).
5. After the input active pixels have been set correctly, adjust total pixels for the
correct active width.
