Let me relate a small story that scared me to death....

I just got my A3000 and a 1950 monitor.  My monitor jiggled as well.
I read in the A3000 users manual that if 'jiggling' occurred there
was a small screw adjustment on the back of the A3000 to correct 
this.  Inside the "using the system software" manual was a little
plastic screwdriver.  I pulled it out and went to the little hole
on the back of my cpu.

I turned the screw.  The manual said you will hear a click as you
turn it.  This is normal, in fact there are 16 turns available.  I
turned.  I got the video solid and then it started again.  Sigh,
I turned again.  Somehow I had managed to miss the little screw
inside the machine and I was _pushing_ on the little rectangular
box that holds the screw.  

I messed my video up quite badly.  I ended up taking the system
apart and pushing the little rectangular box containing the dinky
screw til it was straight.   I then hurled the plastic 'A3000 
destroyer screwdriver' into the corner and broke out my little
screwdriver.  I got my video back, and now it jitters, but not
all of the time.
 
In conclusion, I am not thrilled with the A1950 monitor.  Out
of the 5 we got into the store, most of them are either really
crocked or jittering really bad.   I think I got the best one.

The moral of this story is -- be careful -- or you will get to
purchase a new motherboard.  
 
And the final moral is... throw that damnable little plastic
screwdriver into the garbage. :-)

I do _love_ my A3000 and my 1950 monitor.  Now. :-)
