I finally figured out how to make the VGA out work on my tv and external monitor. I was getting everything from blue and gray screens to stripes. I hadn't seen this posted before so I thought I would post it here.
When I follow this procedure, it works every time:
2-open Display sys pref 3-change to 800 x 600
4-turn external monitor off (for my tv I have it set to pc before turning it off)
5-plug the rgb cord in to your mini
6-turn on the power to your monitor
once working, you can change your mini display back to 1024/600. You can now change settings, like adjust the color on external monitor, or alignment of the two screens, etc. The next time you follow these steps, the settings are remembered.
