Bending
Description
The image hooks, bends, or tears toward the right side of the screen.
This is noticeable on vertical lines near the top of the screen.
Probable cause
This problem is related to sync. The display device is not locking onto
the video as it comes out of the vertical blanking.
Possible solutions
1. Use the vertical shift control to lower the position of the image. See
“Adjusting an image” on page 3-5.
2. Use separate horizontal and vertical sync output.
3. Try using a sync termination adapter (ASTA).
