X11: The Displayed Image Is too Small or Distorted
Support knowledgebase (cg_bildstoerung)
Applies to
SuSE Linux: Versions since 5.3
Symptom
You have configured a graphic card with SaX, but the displayed image is too
small and can be not resized by using the monitor's setting functions.
The image may also be horizontally distorted or a bright stripe
at the upper or left edge may be displayed.
Cause
In most cases vertical or horizontal deflection frequencies have been set
too high. SaX uses the values entered or retrieved from the monitor database
to calculate a modeline with the highest possible refresh rate, since this is
preferred by most users.
Obviously, the monitor's deflection unit does not cope with the
high frequencies, thus distorting the image.
Solution:
Please reduce the highest admitted value for vertical and horizontal deflection
frequencies in SaX at menu item `Monitor'->Properties. The displayed image
will be usually clear and accurate by reducing the vertical deflection frequency
to approx. 85 Hz. Check now if the image is displayed correctly.
