ADC Gain and Grey Scale Alignment
The table below shows a number of NVM settings used for
each model of TV set. Be sure to use the correct editor in the
SAM menu (NVM Editor or SC NVM Editor), because the first
one is used for the Hercules NVM, and the second one for the
SCALER (SC) part of the TV set. For further important NVM
settings, see also the other NVM tables elsewhere in this
manual.
Caution:
•
Do not change the NVM settings without
understanding the function of each setting, because
incorrect NVM settings may seriously hamper the
correct functioning of the TV set!
•
Do not change the Scaler NVM settings, as this will
hamper the DVI functionality of the TV set!
•
Always note down the existing NVM settings, before
changing the settings. This will enable you to return to the
original settings, if the new settings turn out to be incorrect.

The table below shows the NVM settings for panel selection,
based on panel size and manufacturer. Use the SC NVM editor
in the SAM menu to change the panel code at decimal address
320.
Caution:
•
Make sure to choose the right panel, because incorrect
NVM settings may seriously hamper the correct
functioning of the TV set!
•
Always note down the existing NVM settings, before
changing the settings. This will enable you to return to the
original settings, if the new settings turn out to be incorrect.
