I've always been wondering. On most Sony PVM's there's BNC in and out connectors. We can connect to either in or out and get a good picture. What's the danger in using both the in and out connectors simultaneous and effectively giving us two RGB/Component connectors at the same time. I'm asking because the BKM-129X is almost impossible to attain and I don't want to damage my gear.

You should not use the 'out' connectors as an input. You need to put 75 Ohm terminators on the 'out' BNC jacks. Without the terminators the signal will be distorted (probably too bright).

That's on the BVM's. Almost all PVM's have 75 Ohm auto termination. I do have terminators on every out just in case.

Iirc because you need to have a 75 ohm termination. Just get a switch.

I have two 20L4 PVM's with their own scart switchers but I wanted to put one PVM in storage. Well need to use both of them I guess. Or perhaps pull the trigger on BKM-129X.

Just feed one scart switch into the other then connect that to the pvm.
