I just added a A2320 (video enhancer) and A1950 (multi-sync monitor) to my
Amiga 2500/030. I am really happy with it but I have noticed a few little
things, and I don't know if they are normal with the new hardware, or if they
represent a probelm.
1. I have the screen adjusted so that there is no black border, and I have
the H-SIZE switch on the monitor set to ON. If I use the by-pass switch on
the A2320, the screen jumps about 3/4" to the right, so that there is a black
border on the left. If I use an external genlock, it is also off-center by
the 3/4" so I have to wither have the genlock centered, or the A1950.
2. If I have any interlaced graphics moving on the screen, they still seem to
flicker (not stationary objects). If I scroll text in an interlaced CLI, you
can't read the text until it stops scrolling. Could this be a problem with
the Agnus? or the Blitter? I have had a heat sensitive Agnus in the past,
and suspect that this one might be bad as well.
3. I have my terminal screen set to a light grey, and if I'm not going blind,
then the grey seems to grow lighter and darker, while I am using it.
4. Lastely, in addition to the artifacts on the top scan-line I have also
noticed that if I make the right black border visible, that there is an
intermetant jagged edge on the right border.
If anyone could tell me if any of these are normal, or if I might have a bad
A2320, A1950, or possibly something else, I would greatly appreciate it, I
want to get any problems taken care of while everything is under warranty.
Thanks much,

I would just adjust the 1950 such that I don't see this edge. I hope this helps answer your questions.
