Problem: The output resolution can not be set to some of the lower settings.
á Solution 1: The IN1408 can only scale up. Resolutions that would result in scaling down are
not available. If a lower output resolution is desired, connect a signal with a lower Input
Active Area.
á Solution 2: The Active Pixels / Active Lines may be set too high. Reduce the Input Active
Pixels / Input Active Lines setting to match the input signal.
Problem: The desired input aspect ratio cannot be selected.
á Solution 1: The IN1408 can only scale up. Increase the output resolution until the desired
aspect ratio is available.
á Solution 2: Manually decrease the image size by using the output menu.
á Solution 3: Select a different available aspect ratio.
Problem: The output size will not decrease.
á Solution: The IN1408 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.
á Solution: Adjust the Input Total Pixels until the faint vertical lines move out of view or
until only one line remains. Refer to the Advanced Input Settings Section on pages 29-35 to
make the necessary adjustment.
Problem: The image on the monitor has one faint vertical line.
á Solution: Adjust the Input Phase to move the faint vertical line out of view.
Problem: Some characters on the monitor appear fuzzy.
á Solution 1: Adjust the Input Total Pixels until all the characters are sharp.
á Solution 2: Adjust the Input Phase until all the characters are sharp.
Problem: The monitor only displays the upper half of the signal.
á 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.
á 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
Setting to toggle on / off.
Problem: The image on the monitor has jagged edges.
á Solution: The odd and even fields are swapped. For interlaced signals, the odd and even
fields can be switched by selecting Input, Advanced, Scan Type, then Swap Fields.
