keeps saying that the TV is not connected
but it most certainly is... I spent $20 on a replacement proprietary cable so I could make the video out work
any ideas? 1/11/2007 9:12:40 PM |

What driver release do you have for it?
Was that the original video card or one you added on? 1/12/2007 12:12:21 PM |

I'm running the most recent Rage 128 Pro driver from ATI (circa 2001 I think)
it is a discontinued product... but ATI's support sucks anyway so that shouldn't much matter
--
I think the problem might be that the video device I'm hooking this into (an RF modulator) doesn't have enough impedance for the card to recognize that it is attached to a video device
reading some forums has led me to believe that I should make a video cable with a 75 ohm resistor soldered in there somewhere
anyone have any experience with this? 1/15/2007 2:38:00 PM |

sounds to me like you've got your solution 1/15/2007 2:39:39 PM |

yeah but I don't know exactly how the cable should work
what I have read suggests that I should solder the resistor from the core to the shield of the cable... essentially shorting it
my question is: is this a pass-through cable? I should just put the resistor in the middle of an existing video cable? 1/15/2007 2:41:37 PM |

I don't have any experience with this in particular, but shorting the cable doesn't sound like a good idea. 1/15/2007 2:45:25 PM |

that's what I was thinking
where are my A/V and electronics nerds?? 1/15/2007 2:47:33 PM |

Soldering a resistor between two points is not "shorting" a connection you morans. 1/15/2007 2:59:22 PM |

oh yeah?
so... on an RCA cable I've got the two parts - the center pin and the shield
can you explain to me why placing a resistor between these two parts doesn't short it? will this work? 1/15/2007 3:13:02 PM |

The RF modulator has some sort of characteristic input and output impedance. It should be 75 on both ends, but maybe it isn't. Sticking a 75 ohm resistor between the center pin and ground means you are paralleling the input impedance of the modulator with the 75 ohms. If for some reason the RF modulator has a very high input impedance (which is maybe why your card can't detect it), then the 75 ohms will dominate getting you the impedance that the card is looking for. 1/15/2007 3:21:51 PM |

awesome
I'm going to make this cable as soon as a friend brings some resistors over
[Edited on January 15, 2007 at 4:16 PM. Reason : hopefully I've got something that adds up to 75 ohms in there] 1/15/2007 4:15:51 PM |

hmmm
didn't seem to do the trick
the RF modulator's light stays on now as if it were receiving a signal
but my software still doesn't recognize that a TV is connected
is there some way to force TV out? 1/15/2007 9:23:52 PM |

hmmm this is still a problem
god damn this card 1/23/2007 12:28:13 PM |
