Note
•
Input timing should be within the horizontal and vertical frequency ranges in order
to set the screen size and position. Before registering a new signal, check its
horizontal and vertical timing specifications.
•
The factory preset timing is registered when the difference between the user
definable timing and the factory preset timing is smaller than the allowable
deviation; also, the polarity of their synchronizing signals must be the same.
