Or, just so nobody is left in the lurch, an apparently not faulty
brand new cable, that simply hasn't got any wiring between the two
pins that carry the EDID signals. Some cheap cables only bother wire
up the video, sync, and ground pins.
Yeah, that could be called "broken by design". :-)
And there are some monitors that don't bother to provide EDID, at
all.
Though, I only expect that slackness on very old, or cheap, monitors,
or television sets with VGA inputs.
I do wonder how well EDID circuitry handles hot plugging, and whether
it gets blown by people un/plugging while all the gear is running
(monitors and computers).
I never ever ever (un)plug a VGA cable on a live system. Not even on
laptops, where this is supposed to be safe. I had some very bad
experiences with doing that --- burnt graphics cards, burnt monitors,
burnt motherboards, etc. Since then I typically disconnect everything
from the power outlet before mangling video cables.
Best, :-)
