Studio Display and 9.2.2
Posted by: jack on 2018-01-07 14:15:53
I'm running 9.2.2 on a QS G4 with a Studio Display.

The display functions fine, but I'm not able to control brightness or use the USB on the rear. Is there some sort of special software I need to make this work?

Likely a silly question, but you are using ADC and not running it through a DVI converter correct?

Yeah, ADC connector plugged right into the card. Nothing in-between.

I have another QS with Mac OS X on it. I'll have to give the display a shot there to make sure there's nothing wrong with the display itself.

I have a Studio Display with my Cube and there wasn't anything additional I needed for the USB ports to work, and the Monitors control panel recognized it was a Studio Display and gave me the brightness slider without me having to do anything special.

I will be interested to see if you figure this out.  My Studio Display and QS G4 do the exact same thing.  Power button works fine, brightness and USB ports do not.  I don't recall that it matters what operating system - stuff just flat out doesn't work.  Pretty much factory stock hardware configuration on the G4 too, makes me think that it's a software issue.

So I did a bit of fiddling:

For me, it's definitely not software related. I tested on Mac OS X (on another QS), and it worked fine. Then, I went back to test it on the 9.2.2 machine, and it worked. Briefly.

The brightness would occasionally disappear out of the control panel, and USB devices would occasionally disconnect. I honestly think it's just a flaky connector.

Next thing to try is to swap the two graphics cards, see if the connector from the card in the OS X machine is any better.
