I tired hooking up my multisync monitor I have hooked up to my DEC 3000, but I don't think the graphic card is set to a setting within the monitor's range, as nothing shows up.

Do the DEC 3000 have a VGA port?

No it has a 3W3 port and the cable outputs to BNC connectors.
One built-in and one on the add-on graphic card.

Aha. So it's video signal with sync on green. You need to have a monitor 
that can handle this. Many today don't...
That is most likely your problem, and not frequencies...
