RCA to VGA?

Is there some kind of adapter I can attach to a PC monitors VGA port so I can connect my camera to it and use it as a field monitor? I have an old, old Commordore 64 monitor which has that kind of input and the picture comes out clear on it, except the picture is continuously rolling vertically, so it's obviously not useable, or is there anyway to fix it?

There should be a setting to control vhold.

If not, check for ground loops. To debug ground loops, one solution is to have all wiring off the same power outlet... you might just want to isolate the monitor and video source to debug (like disconnect them, and reconnect them somewhere else).

2- Commodore monitors should have 2 RCA plugs in the back... you can make yourself that cable as follows:

Get a S-video cable. This goes into your camcorder... use the camcorder as a DV bridge if you need to see your NLE.
Get a RCA cable (male-male; almost all are male-male). Cut this in half.

Make a S-video to dual RCA male cable.
Strip open both cables. Shield goes to shield/braid, center wire to center wire. To start, just tape everything onto a business card and keep the wires seperate.
One of the RCAs will carry luma, the other chroma. Via trial and error, you should figure out which is which. So label them accordingly.

Once you got that figured out, either solder your cable or buy a new one. cablewholesale.com I think has em.

Hmm, at the back of the monitor there are little holes with "V.H' "V.S" and some others...I assume VH is vertical hold? How exactly do I use these settings...are they screws in those holes or what?

Probably screwheads on the shaft of a pot or coil. If you shine a flashlight in you should be able to see for sure. Use a non-metallic screwdriver (available at Radio Shack).

Ahhh, that helped...But the monitor is officially wonky. Luminance and Chromanance jumps, it also seems to lag...If I move the camera, the low-lights seem to take a half second to adjust...Shadows will move with the picture before being adjusted...But I guess 20 years will do that to monitor.
