I have 3 Panasonic crt tvs, one built in 2001 and 2 built in 2004. On each the settings scale for color, brightness, picture, and sharpness goes from 0-63. Anybody know why that is? Is 63 supposed to represent 100, or did the engineers figure there was no beneficial reason to allow the user to go beyond 63?
64 bit digital including that 0, probably D-to-A converter steps. My old 27" has that one and 16, 32, and 128 in its service menu adjustment ranges. What's odd is my Panny WX50 uses -30 to +30 (including 0) in its user menu settings scale like you mentioned above; it would appear I lost 3 bits.
