Back then, the OP appeared to use "hardwired" differently from how I would. I've never seen a monitor that could be hardwired to anything: all have had sockets on the back. Ditto personal computers. My monitor with the flickering colours was firmly attached with screwed-down D plugs. That doesn't guarantee electrical reliability of the individual pins. OTOH I've only experienced Out of Range complaints when guessing the settings for a new (to me) monitor/TV. Cheers, David.
