Resolutions
As a handy reference this table indicates the different scanrates,
and screenmodes available. This table is based upon information
from a wide range of sources, particularly articles written by
Simon Goodwin.
The table is broken down into six headings.
Scanrate - Indicates differing standard screen
sizes. NTSC is an American standard made up of 525 screen lines
refreshed at 30 times per second. PAL is a European standard
that consists of 625 screen lines, refreshed 25 times per second.
Screenmode - Highlights the name of the
resolution.
Resolution - The number of horizontal and
vertical pixels that can be displayed on screen. The higher the
resolution, the greater number of pixels there are and the better
quality the picture.
Colour Range - The number of colours available.
For example NTSC Low Res allows a range of colours from 32 to 4096
on screen at once.
Chipset - Indicates the Amiga chipset required
to use this mode. "All" suggests that every Amiga is capable of
displaying this mode, Enhanced refers to the ECS chipset, and AGA
indicates AA-based Amigas such as the A1200 and A400
Genlock - A Genlock is used for video work,
outputting to a video display. This indicates if the mode is
compatible or not.
