Cable to connect a color video monitor to an VT240

[cjs]

Obviously, the monitor does not support SOG. I found a manual of a similar (but not exaclty my type) monitor stating SOG compatibility.

Ah, good to see things got figured out.

This is something you have to be careful with when using PVMs: there are often models that look very similar but have substantial differences in the types of signals they will accept. And this can happen even between instances of the same model, depending on the options installed.
