Just curious...
How liniar they are depends on your definition of that term. They seem to
respond well to an R=G=B gray balance if thats what you mean... with the
exception of Apple LCDs which have a hack that makes them well gray balanced
already, while not displaying balanced curves on measurement (one of those
Apple quirks). LCDs do not, however, have nice smooth gamma shaped curves,
varying from slightly off shape curves to ones with zig zag angles and near
reversals in them. So for all LCDs except Apple's you do indeed want to bring
the curves to 2.2 (or 1.8 or some such) but its still interesting to see what
the native gamma is, and occasionally useful to match it, for testing
purposes.
