Problem: The display device has a double image.
Solution 1: The IN1404 cannot separate multiple signal formats. Make sure that only one signal
is connected to each input.
Solution 2: The odd and even fields are not properly detected. For Component B and RGB
interlaced signals, the detection of odd and even fields can be corrected by selecting
Input, Advanced, Scan Type, then Invert sync.
Problem: The image on the display device is black and white (no color).
Solution: Set the input signal format to match the input signal connected to the rear of the unit.
Problem: The picture on the display device has hooking along the top.
Solution 1: Increase the input horizontal tracking to compensate for poor quality video signals
(such as from a VCR).
Solution 2: The display device may need different sync serrations. Choose a different output
sync from the sync format menu.
Problem: The image is frozen.
Solution: Freeze is activated. Press FREEZE to deactivate the freeze frame feature.
Problem: The image on the display device is the wrong shape.
Solution 1: The input aspect ratio is set incorrectly. Adjust the input aspect ratio to match the
input video signal.
Solution 2: The output aspect ratio is incorrect. Select an output resolution to match the display
device.
Problem: The image on the display device appears fuzzy.
Solution 1: Adjust the video sharpness until the image regains its detail.
Solution 2: Adjust the video noise filter until the image is sharp.
Solution 3: Change the comb or trap filter setting.
Problem: The output resolution will not decrease.
Solution 1: The IN1404 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.
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.
