To get the best contrast on the waterfall display set the REF LVL so
that the noise level is right at the bottom of the spectrum display.
And then adjust the SCALE to make the signals higher on the display.
The waterfall and spectrum use the same REF LVL and SCALE values, so the
more the SCALE is turned up the greater the contrast on the waterfall.

Tnx for all the responses. I may have poorly stated my question. What I was
trying to say is the waterfall traces seem dim both on P3 and on the monitor I
am using (dedicated to P3 SVGA). Even though signals seem relatively strong in
spectrum display, they are not bright and are monochromatic in the waterfalls
on both displays. Maybe that is just the way it is. I have tried adjusting SVGA
bias (didn't see noticeable difference) and LCD brightness.
