Clear as mud.
Monitor = display. This is physical.
Screen for X purposes is comprised of from 1 to N displays aka 1 to N monitors,
and most often is. It's a logical construct in which displayed output can be
either mirrored (cloned) or discrete (unique).
IME, two cables simultaneously connected from one GPU to one display is a
formula
for failure, unless the display specifically supports multiple simultaneous
discrete inputs, such as PBP, POP or PIP.
