This is first time on OC. Don't know if this question is "Appropriate", since it has nothing to do with overclocking. Searched the internet, and couldn't get an answer. I have a 3870 on a Mac Pro dual core from 2008. 10.5.6 and such. I haven't been able to get the tv(S-Video)out, to work. The dvi works great. When it's plugged in, it doesn't even show under system profile. Any suggestions would be appreciated. What I have it plugged into, is a Sony video monitor. Thanks.
