    Post resistor question with lcd and tv out

    I've read that the internal resistance in most lcd screens is not enough for my ati card to pick up when i use composite out. I take it I have to add in the 75 ohm resistor. I went to 2 radio shacks and none have it. They have resistors in the 80's. I'm guessing that should work but i want to know if anyone else has tried it.

    Works great. 82 ohm is what I used and it worked immediately.

    I'm using an 85ohm and it seems to work.

    I just was reading a manual for a camera I have and it needs 75 ohm on the composite video out too. They show using a BNC T connector to split the feed and then using one of the outs on the T feed your monitor on the other use a 75 ohm BNC terminator. It is basically doing the same thing as wiring in a resistor yourself but for testing it doesn't require any soldering. Only problem is you will most likely have to use adapters from RCA to BNC but those are easy to get as well. Proabably building a RCA to RCA cable with the 75-80+ Ohm resister is the best way to go.
