Yeah, but if the DSUB cable was fat enough, the fact that the RGB
signals were bundled wouldnt make any difference, provided they were
all properly individually shielded (they almost always are these days)

Ive NEVER seen an extention cord for a monitor (at ANY cost tho some
are worse than others), on the other hand, that didnt severely
deteriorate picture quality. I think this is a capacitance issue - the
monitor is calibrated at the factory for a particular cord ...
