Hi,

You can't assume that. A Native LCD response is nothing like a CRT (it doesn't
have a power curve response), so all LCD displays process the signals to make 
them
respond more like a CRT. This processing can be quite intrusive, and
may take a form that wrecks any additivity assumption.

It's impossible to comment without anything to go on. Please email
me (_not_ the list) the .ti3 file in question.
