View Full Version : Serious brightness issue (causing blindness!)

Jun 10, 2011, 02:41 PM
I really need your help, I'm becoming blind here. Everytime I connect my MBP to my iMac to use as an external display, the brightness of the iMac's screen gets to its maximum and I have found no way to change the brightness. I tried to lower the brightness on my iMac before hooking it up to my MBP, no luck. i've tried to find an option to change the brightness but there's only a slider for my MBP's screen not for my iMac's (see print screen, okay it's in dutch but "helderheid" is translated to "brightness").
I've had this issue in SL as well, but when I changed the brightness on my iMac it would stay the same when I hook it up to my MBP....

Does anyone have a solution for this? Because it's really hurting my eyes...

Oh, I also tried to do screen sharing from my MBP, so I could go to settings on my iMac, but the brightness slider isn't there as well...
