Hi

BDelay=93 for NTSC and ADelay=127, BDelay=114 for PAL (B,D,G,H,I). I'm guessing that the Ini file setting InitialBDelay is related
to BDelay. Does DScaler not set BDelay and ADelay when switching between PAL and NTSC?

The BDelay (ini parameter InitialBDelay) is different if you choose to save
settings by TV format : 92 for NTSC, 114 for PAL and 176 for SECAM.

this changing the luma boundary ? (modifies the whitest white we can get as well as the blackest black) ??

Michel, a person from the french forum, has made a lot of tests, analyzing
test patterns, with and without full luma range. He concluded the result is
exactly the same if you activate the full luma range and add 16 to brightness.
Same black and same white.
Personally, I make tests only for Pal, but I have the same conclusion.

So, I think we can advice to check full luma range (which is the default in
DScaler) and adjust correctly brightness.


Concerning ADelay, this parameter is not in ini file. Don't know the value used
and if the value changes with TV format.
