I just bought a 17" Studio Display (ooohhh..... droool) and noticed something odd. Whenever I launch iTunes 2 in OS9, the gamma of the screen changes to a slightly darker setting. I then quit iTunes, but it stays the same. It only shifts back to it's slightly brighter position when I reboot.

Anyone else seen this?

And while I'm at it, how in the world do you control the brightness of the display in OS 9? I obviously figured out how to press the brightness button on the display in OSX to reveal the monitor control panel (with brightness slider) but in OS 9 there isn't anything.

Never noticed the gamma thing. In OS 9, the brightness button on the monitor doesn't bring up the "monitors and sound" control panel? I never installed the monitor software because when I tried the installer would quit saying "this software doesn't work with this computer". Maybe my quicksilver is too new (?). Anyway, you should just be able to open the monitor & sound control panel manually to change the brightness.

Yup, the gamma thing happens on my 17" Studio display too. It's a bit different in my case though. There's no change when I launch iTunes, but when I quit iTunes, it switches to a lighter gamma, then after a half-second or so back to the one it had before.

It's interesting that these gamma quirks occur in both OS 9 in your case and OS X in mine. I wonder if this is specific to the 17 inch Studio Display, or if others are affected too. Perhaps all of Apple's LCD monitors? If it makes a difference, I've got my display connected to a 733 QS G4. I'm using iTunes 2.0 (haven't grabbed the 2.02 update yet).

Interesting. I noticed this yesterday when quitting an launching iTunes on my PowerBook G4. I think maybe it's a setting like Quicktime has that's "Theater mode" or something. Dunno.

Well, I actually have the Theater Mode extension turned off, so I don't think that's the cause of the brightness shift.

It would seem (novice here) that iTunes is engaging some video mode extension, I would assume it's "Visuals", when launched. It's kind of annoying...

I have a LaCie Electron 22blue CRT and have been noticing this for some time now. I keep forgetting to investigate it. I get the shift at iTunes quit, and as mentioned above, it seems to shift back after a second or so. I was thinking it was a profile thing. Maybe the monitor profile selected is temporarily disabled and then reselected? Sure would like to see this cleared up.
G4 450 AGP
OS X
iTunes 2.0.1 (but have noticed this back in 1.x)
