NEC Mt820 Projector Users Manual

							Changing Video Resolutions
Depending on your computers graphic capability, you may be able
to select one of several resolutions. Generally a computer- either a
PC or Macintosh- with 1 meg. of memory will run:
6402480 at 16.7 million colors (24 bit Truecolor)
8002600 at 65 thousand colors.
10242768 at 256 colors.
As the resolution increases,  the number of colors you can run
decreases.  With 2 meg. of memory a computer will run:
6402480 at 16.7 million colors (24 bit Truecolor).
8002600 at 16.7 million colors (24 bit Truecolor).
10242768 at 65 thousand colors.

Notebook Computers And Resolution Standards
NEC projectors are designed to project industry standardized video
such as VESA (Video Electronics Standards Association) or VGA
(Video Graphics Array). Notebook computers do not use industry
standards. They use whatever timing is necessary to match their local
LCD display. The end result is typically not standards. By turning off
your notebooks display, the timing parameters are a bit more like the
real VESA or VGA signal.
For an optimal projected image with a notebook computer, it is
recommended that you use the CUSTOM 6 memory data. This feature
is useful when an XGA image (10242768) is displaying with a
notebook computer supported by SXGA (128021024) and when an
SVGA image (8002600) is displaying with a note book computer
supported by XGA (10242768). See Source Menu on page 52 for
more information.
