1.7.4.8. H.TOTAL (for S.ANALOG input)
This adjustment is normally unnecessary. The optimum value is automatically set in
automatic input signal scanning.
Used to adjust a total horizontal dot number of an input signal. Incorrect H.TOTAL value makes
vertical striped noises or jitter noises on an image, or whole effective area cannot be displayed
even after the image position adjustment.
[Procedure]
1. Select H.TOTAL in the input memory menu (on the 3rd menu sheet).
2. Adjust to eliminate the vertical stripe noises by left/right button.
3. If the horizontal position shifts after the adjustment, adjust H.POSITION (chapter
1.7.4.1, on
page 58) again.

Incorrect CLAMP setting makes whole image darkened and uneven horizontal brightness
appears on the image. CLAMP is automatically set to the optimum value when you set
CLAMP START=0, CLAMP WIDTH=0.
[Procedure]
1. Select CLAMP START in the input memory menu (on the 3rd menu sheet).
