Re: Can’t adjust brightness on ADC monitor
(What's happening? I was sure I had posted this already...) OK, I did my homework better this time and it turns out the button on the screen's frame (Apple Studio Display 17) doesn't bring up the brightness dialog even when it's the only screen connected to the PowerMac. That's not as I remember it, but I can't say 100% sure that it has worked correctly in the past, because I've been working with several such screens. So I looked around where the display prefs are and moved them (there were two files) to the desktop, then restarted. The button's behaviour remained the same: it lights up when pressed, but no dialog box appears. Anyway, no new prefs file was created until I changed the profile of a monitor, which gives me the feeling these display prefs are not involved with this error. Maybe it's hardware, after all? Or the system software? I really don't know. I guess the next step will be to borrow a ADC screen and see how that behaves on this computer, or connect this screen on a different PowerMac. Now implies something has changed...what is it? Do you get the expected behavior back when whatever that is is undone? You should be able to do everything separately on the two monitors. Did you try trashing the display prefs?

Can’t adjust brightness on ADC monitor
I have two monitors on a PowerMac G4 (dual 500MHz): one is a Viewsonic on DVI, the other an Apple Studio 17 on ADC. Is it normal that I can’t adjust the brightness on the Apple monitor now? There’s no slider for it in the screen’s preferences, and pressing the button on the screen frame doesn’t bring up the usual dialog. Maybe I should mention that both monitors are connected to the same graphics card, a GeForce4 MX (AGP). If this is indeed the common behaviour, my theory is that the OS (10.4.11) can’t get a handle on the Viewsonic’s brightness, and then disables the software control for both. But I think it’s strange, given that other settings can be adjusted for each screen separately. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
