Yes, you have a defective 1950 monitor.  Take it back to the dealer you
got you system/monitor from and get it exchanged.  Some of the first
couple thousand monitors had a vertical jitter problem which was later
fixed.  The offical policy on this is to get it exchanged at you dealer.
I would see what the serial number on the back of the monitor is and
only exchange it for a monitor with at least a couple hundred larger
serial number on it.
