Apple Computer, Inc. July 2001
Video Display
The built-in video display uses a 15-inch CRT (13.8-inch viewable
diagonal). The CRT uses shadow-mask technology and has a dot pitch of
0.28 mm. The display has a fixed horizontal scan rate (60.015 kHz) and
supports three resolutions.
[305]Table 3-4 lists the resolutions and the vertical scan rates
supported. [yada yada] The display supports pixel depths up to 32
bits (millions of colors) at all resolutions.
The iMac computer has a port for an external video monitor. The
external monitor shows the same information as the built-in display, a
mode sometimes called hardware video mirroring. The external monitor
supports only the display resolutions that are available on the
internal monitor, as shown in [306]Table 3-4.
Table 3-4 Display resolutions and pixel depths
Resolution Vertical rate Pixel depth
640 by 480 117.233 Hz 32 bits
800 by 600 94.97 Hz 32 bits
1024 by 768 75.03 Hz 32 bits

It does do 1280x960, too, but it's kinda uncomfortable on my eyes.
