Hi all!

I am not sure this is the right NG to ask the question – but I’ll give it a try.

Last week I bought a new TFT monitor (Sony SDM-S93) for my trusty G3 B&W running OS X and Adobe CS. After connecting the new panel sometimes RGB is off, only purple and green.

After switching the OS on the first time, the desktop image was purple-green (PG), only the original desktop images from Apple were displayed correctly. Checking a second G3 gave the same result. Using my scanned images colors were off.

What is happening – I don’t know, sometimes colors are OK and now they are off again.

Opening a .TIFF image in PS now is PurpleGreen only, opening the same image in Illustrator is RGB as it should be.

– using my older CRT monitor colors were OK in same setup – using a smaller and cheaper Sony TFT colors are OK in same setup

I can’t put my finger on yet but I get the feeling that PS is interfering somehow with general display settings.

Any thoughts on this – anyone??

It maybe that the monitor itself is at fault. After upgrading the second Mac to OS X 10.3.4 I made a comparison between the two TFT displays in the OS Calibration app:

Older SDM-S51:
native white point 9242 Kelvin
selecting or de-selecting the <Use native white point> checkbox does not make much difference.

New SDM-S93:
native white point 5759 Kelvin
selecting <Use native white point> gives good colors in calibration window, deselecting turns everything monochrome pink no matter what the position of the color temp slider is.

I tried to <Grab> the pink display colors but after going back to native white point (check box selected) the colors in the TIFF image were normal too.

The abnomalities must be in the display.

Sliding the white point slider back to 5317 K gives a very strong monochrome pink, moving it further to the left to 5292 K and lower, I get two colors – green and pink.

I’ll take it back to Sony tomorrow.
