Well after getting many questions about what display mode does what (not
many people have A4000's in Oz yet!).  I wacked up a little program to give
me all the info.  I hope it answers some questions for people....
 
Terms-
 
ECS is the SuperDenise/Obese Agnus (The one which allows 1 or 2 meg of chip
etc).  In all A600/A3000's and most recent model A500/A2000's.  Early
A500/A2000 models should be able to be upgraded to it.  A1000's and some
VERY early A2000's need major changes to allow upgrading to ECS.
 
AGA is the chipset that is in the A4000/A1200, there are no ways currently
to upgrade a A500/A600/A1000/A2000/A3000 to it.  Probably never will be.
 
Notes-
 All these monitors except the AGA DBLPAL & DBLNTSC ones are supplied with
 Workbench 2.1 or later.  I am using the 3.00 ones.
 The KHz/Hz might be a bit off.
 ECS/AGA means the mode requires ECS OR the AGA chipset.
 ANY means all chipsets released to the public.
 Some of the DBLPAL & DBLNNTSC modes came up as available with ECS I beleive
 this is a bug in 3.00 so I changed them to AGA only.
 VGAOnly is a special thing that you put in your monitors drawer to try
 to keep the frequencies fairly normal.  Many people are using it for
 better mode to mode screen positioning.  It does lose horizontal
 scrolling ability in the productivity type modes (multiscan, DBL etc).
 
This is without using VGAOnly:-
