Can P3 output to a monitor?

[Eric Swartz - WA6HHQ]

End of thread.

OT and way over the pain threshold for OT list posting volume.

Please, when you see a OT thread get too many posts like this, resist
the urge to reply via the list. Direct email to individuals works well too..

All of that is true in its proper context, but off-topic here because
NONE of it is limiting the present performance of the P3.

At present the frequency and time resolution are limited only by the
numbers of PIXELS in the small 480 x 272 display. There's a lot more
performance waiting inside the P3, and the VGA display will show it to
us.
