Need advice on JVC RGB Monitor

I've just realized a professional crt monitor thats cheap and easy to find in my country (BRAZIL).

JVC Brand, This is a picture of the inputs. Its bnc (?), but i think something is wrong. The number of inputs for each video signal is different from sony pvms. Someone knows?

INPUT A: They are composite video & mono audio inputs. INPUT B: No idea what that is, Y/C INPUT: No idea.
Sony PVM's have separate inputs for R,G,B + Sync (mainly BNC - 4 Connectors per Video input)

 

y/c is S-video, VTR is an Old SChool input for old vcrs and tape decks. i have adapters here at work that turn that y/c plub into either two connector BNC or standard 4 pin mini din

 

So, this is not a rgb monitor at all, it seems...

 

exatamente, Isso não brega

 

Input A is standard composite.
Input B (VTR) is like what Skyway said. It is an S-video signal over a special connector
The Y/C input is S-video using JVC's proprietary 7-pin connector.

So no RGB on this monitor.
