The DSUB cable I have is the one which came with the screen. As it came together with a 21" Philips, I'd say that's probably as good as
they get.
BNC splits up into 5 cables which then connect to the screen with coax connectors. So less signal quality loss. Keep in mind that VGA is
an analog standard.
