Hi,

I have a problem with a dark iMac (DV 500MHz) screen, and in my search for a solution I found the following on Apple's support forums:

[i]"Often this problem can be fixed by adjusting the transformer. I don't know if its necessarily correct to do, but I maintain a school full of computers, and have done this very thing many times.

Sup guys, I'm trying to figure something out with my display options in OS X.2.8 but I'm stumped. I thought maybe I could bounce it off you guys' grey matter. Sorry for being long-winded.

I'm trying to get my TV/S-vid out to mirror the VGA of my main Radeon 8500 AGP card. I have a ATI Radeon 8500 AGP 64MB and an ATI Rage Orion PCI 16MB both with 17" VGA monitors attached. If I hook up a TV/VCR to the TV/s-vid out on the 8500 it splits the 64MB VRAM to 32MB each as it should. I have three displays I can scroll across. That part's no sweat...
