Q: iMac G5 iSight detects external display when none is connected

Hi,

 

I purchased an old 17" iMac G5 iSight,in which the screen sometimes suddenly turns to blue and the resolution drops as it detects a VGA display even though no external display is connected. It even shown two displays in the preference panel.

 

I opened the iMac and checked the capacitors which look okay. I reinstalled the OS and it didn't fix the problem.

Do you have some idea where to look? Or does someone know how to disable external displays?

 

I found this discussion from another forum: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/172427

...but it's ubuntu so I don't understad what they're talking about?

iMac, Mac OS X (10.5.8), 17" iMac G5 iSight
