	*sigh*, why ME?!  Here I am with my wonderful new Sony MultiScan, only 
it's not so wonderful.  The display is very sharp and very steady, but it's 
twisted.  Here is a more precise description of the problem(s):

	The display has an hourglass shape, that is, the scan lines toward the 
top and bottom of the screen are longer than those in the middle, making 
vertical lines bend outward at top and bottom.  This effect is slightly more 
pronounced near the top left corner.

	The whole screen image is rotated slightly, but noticably, clockwise.  
I.e., the scan lines are not quite horizontal; instead they end up lower on the 
right than they started out on the left.  The scan lines also do not appear
completely straight, but this may be an optical illusion due to the other 
problems and the convexity of the tube.

	The right edge of the display, just where the beam shuts off, is ragged.
About 2mm of each scan line is slightly darker than the rest, and this narrow
vertical zone flickers.  I suspect this is normal, but when the horizontal
position control is adjusted to move this region behind the bezel, there is not
enough overscan on the left edge, even at maximum horizontal size.  The left 
edge is sharp, but has the hourglass problem.

	All of this is with NTSC, both interlaced and non-interlaced.  I've 
tried wiring the sync both horizontal/vertical and composite, each with the 
same results.  
	Has anyone had similar problems with this Amiga/Sony CPD1302 
combination, and been able to fix them, specifically the lack of sufficient
overscan?  Can anyone tell me what it'll take to straighten out the
electron beam?  Does the monitor need to go into the shop?

	Please dispense wisdom, o video wizards!  And AdvThanksance x 10^6!!
