One other thing I've found (at least with my Sharp):  If you put the 
picture beyond the top left corner, it will not sync properly.  I get 
horrible images, lost colors, ghosting, etc.

So I set up the modeline to intentionally shove the picture to the 
bottom right and to reduce the image, even if it means huge black bars.  
Once I have a sync, then I start moving the picture up and left and 
filling the screen.  (This takes far too long, as I am too often 
interrupted by the mandatory 87th viewing of Cars, 20,000 leagues under 
the sea, or some such emergency.  :-) )
