The video quality of several CPT monitors
seems to be a strong function of how long they
have been powered on! The monitor currently
on CADR-4, for example, looks perfectly ok
for a quite a long while after powerup, but
eventually becomes barely usable.
This probably also explains why a number of
monitors flushed for "poor focus" work perfectly
OK when tried later.
We should determine what causes this. (Probably
something getting hot).
Until we can work out a better solution, I ask
users to turn off certain CPTs when they are not in
use. Currently, I think CADRs 1,4,9, and 10 will
benefit. Hopefully, we can soon come up with
a real fix.
