Actually the best solution in Amiga mode is to use a ScreenMode requester
and let 'em pick for themselves...

Yes - I tried this again to be sure:
A1400T NTSC Amiga
Composite output hooked to TV (tested with "forced" screens, and with
screens selected with ScreenMode requester)
Screen
NTSC lo-res : OK
NTSC hi-res laced : OK
PAL lo-res : picture "rolls" - if corrected with vertical synch
(very tricky to stop rolling) bottom of screen is not shown
PAL hi-res-laced : same as PAL lo-res
Output to PC style Multi-synch monitor through flicker-fixer/scan-doubler
card:
All standard PAL and NTSC screenmodes OK (including Blitz-mode)
Normal RGB output - can't test (I have no monitor that can use it)
The problem for NTSC TV's is simple - there are just too many scan lines in
PAL modes to be displayed by a NTSC TV
