Converting TTL monitor to Analog

I'm acquainted with the effect, but not in the context of this class of device.
It must not like to show itself in the range of brightness in which the monitors
I've tried this with in the last day or so opeprate. This suggests we're making
a mountain out of a molehill, at least in the context of the problem at hand.

How does that relate to the "digital" vs. analog debate? I can see how sweep
rates figure in, but the input signal levels?
