Apple Performa Plus Display M9102LL/D

[Shinobi Kenobi]

I just reinstalled Photoshop for the first time in a long time, and I'm configuring the gamma. Does anyone know what type of phosphors this exact model used? I guess I don't HAVE to set it to the correct ones, but I would like to. The service manual doesn't specify that info.

The available choices are:
EBU/ITU
HDTV (CCIR 709)
NTSC (1953)
P22-EBU
SMPTE-C (CCIR 601-1)
Trinitron

The display appears to be a Goldstar-built 14" shadow-mask CRT. These types of monitors were generally using the 1.8-gamma color space.

The choices you list are all incorrect; most are for non-Mac devices, with the Trinitron being the exception -- but your display is NOT a Trinitron display. Your best bet would be to generate your own ICC profile; if that's not an option, setting gamma to 1.8 will likely get you "close enough".
