It all depends on which Mac model you have, what video card is installed
(if relevant), what adaptor is used between the video card and monitor
(if appropriate) and what the monitor claims to support.

The standard resolution on my iBook is 1024x768, and it also supports
640x480 and 800x600 (interpolated on the LCD screen, all modes are also
available on the VGA-compatible output).

Older Macs and their monitors have fixed resolution (very old machines
were black and white).  More recently, multi-scan monitors became the
norm (as on PCs).

640x480 has been the lowest common denominator for a long time.  Most
Mac models have supported at least 800x600 for several years.

The early iBook models are worth noting - their maximum resolution is
800x600.  The iMac G3's default resolution is 800x600, but it also
supports 1024x768.

Slotted Macs and professional series laptops can also support multiple
video cards, with independent monitors which can have completely
different display modes, and which can be arbitrarily arranged by the
user.  This has been supported since about 1987 (Mac II).
