That's very possibly your problem.

I would suggest regardless you get a Commodore 1950 or 1802 and try
those, with the proper cable (four wire). It's very possible that
I am wrong, but I would rule out the possibility that you have the
wrong monitor/cable combination first. I know that with the Amiga
systems this is also an issue.
