A2000 picture problem

[glitch]

Black and white output on the composite out port on the motherboard is normal.  Did you not get anything out of the composite out on the 2300?

Your Samsung plasma display may not be able to sync low enough to see anything off of the RGB port, so that might be normal.

Try the 2300 again and let us know.

With the little toggle switch in all three positions?

The switch gives computer video only in one position, video only in another and computer video overlayed on top of video in the other.  This is good!

Could you put a composite signal through the genlock to see whether it is oddly coloured as well?

Good luck!
