Problem: The desired input aspect ratio cannot be selected.
Solution 1 : The IN1404 can only scale up. Increase the output resolution until the desired aspect
ratio is available.
Solution 2 : Manually decrease the image size by using the output menu.
Solution 3 : Select a different available aspect ratio.
Problem: The output size will not decrease.
Solution : The IN1404 will only scale up. Increase the Output Resolution, and then reduce the
size of the output image.
Problem: The image on the monitor has multiple faint vertical lines.
Solution : Adjust the Input Total Pixels until the faint vertical lines move out of view or until
only one line remains. Refer to Advanced input settings on pages 23-28 to make the
necessary adjustment.
Problem: The image on the monitor has one faint vertical line.
Solution : Adjust the Input Phase to move the faint vertical line out of view.
Problem: Some characters on the monitor appear fuzzy.
Solution 1 : Adjust the Input Total Pixels until all the characters are sharp.
Solution 2
: Adjust the Input Phase until all the characters are sharp.
Problem: The monitor displays only the upper half of the signal.
Solution : The Input Scan Type is set incorrectly. For non-interlaced signals, select Input,
Advanced, Scan Type and verify that the Interlaced Setting is turned off. Select the
Interlaced Setting to toggle on/off.
Problem: The image on the monitor jitters up and down.
Solution : The Input Scan Type is set incorrectly. For interlaced signals, select Input, Advanced,
Scan Type and verify that the Interlaced Setting is turned on. Select the Interlaced

Solution : Your settings may be outside the range of predefined modes. Switch to the User
Defined Mode to allow for a full range of settings. Select Input, Advanced, Input
Mode, and User Defined.
Problem: The input total pixels setting will not decrease.
Solution 1 : The Input H-Blanking may be set too high. Reduce the Input H-Blanking to match
the input signal.
Solution 2 : The Input Active Pixels may be set too high. Reduce the Input Active Pixels to match
the input signal.
Problem: The input active pixels setting will not increase.
Solution 1 : The Input Total Pixels may be set too low. Increase the Total Pixels setting to match
the input signal. Refer to Advanced input settings on page 23 to make this adjustment.
Solution 2 : The Input H-Blanking may be set too high. Reduce the Input H-Blanking to match
the input signal.
Solution 3 : The Output Resolution may be set too low. Select an Output Resolution that is
greater that or equal to the Input Active Area.
