Thanks, mauikurocat (maui black cat?). Yes, I have a Radio Shack closeby, and I'll get the part. Did seem like it twisted off all to easily, very surprised how easily it twisted off. So this appears to be a common issue and not just with the Envision monitors.

Edit: this connection piece broke off a TV tuner module that slides into a monitor. Monitor has vga to accept the coaxial cable basically. Maybe I'll try the vcr route, if that doesn't look right, I just use the envision for a 3rd monitor.
