I just hooked up an old CRT to my 12" powerbook. It works, but the screen on the external is very very dark. So dark that if I cannot make it better I'll have to throw the thing out. Yes, the brightness and contrast are set to brightest. I've fiddled with all the controls in monitor prefs. as much as possible. I got this monitor for free from my college (which didn't want it anymore), so perhaps that should tell me something. I'm assuming that this monitor is just dying and there's nothing to do. But before I just toss it, I thought I'd see if anyone had any ideas. edit: also worth noting that windows on the external seem to curve in towards the center. Not sure if that's a factor or not.
