Not necessarily. At one of my jobs, we make a turnkey appliance that typically connects to a user- (or at least dealer-)supplied monitor, potentially with a locally-sourced cable.

Quite true. I have an old ViewSonic LCD which sometimes sends *wrong*/no EDID data even when the (VGA) cables are OK. -RVP
