i'm using my iMac 27" as external monitor for MacBookPro (via minidisplayport cable).

Recently i noticed that i can't change brightness on iMac (when used as external monitor). Previously i was using iMac keyboard to adjust volume and brightess even when connected to MBP.


I'm sure it was working before. I suspect 10.6.8 update broke something.

Can anyone confirm? Do you have a solution?

Full brightness makes iMac screen unusable for me. :/




iMac, Mac OS X (10.6.8)
