Changing the computer’s video
resolutions
Depending on your computer's graphics capability, you may be
able to select one of several resolutions. Generally a computer-
either a PC or Macintosh- with 1 MB VRAM will generally run:
640 × 480 at 16.7 million colors (24 bit true color)
800 × 600 at 65,000 colors.
1024 × 768 at 256 colors.
As the resolution increases, the number of colors you can run
decreases. With 2 MB VRAM a computer will generally run:
640 × 480 at 16.7 million colors (24 bit true color).
800 × 600 at 16.7 million colors (24 bit true color).
1024 × 768 at 65,000 colors.
1280 × 1024 at 256 colors.

Notebook computers and resolution
standards
The unit is designed to project industry standardized video such as
VESA (Video Electronics Standards Association) or XGA
(eXtended Graphics Array). Notebook computers do not use indus-
try standards. They use whatever timing is necessary to match their
local LCD display. The end result is typically not standard. By
turning off your notebook's display, the timing parameters are a bit
more like the real VESA or XGA signal.
Outputting Notebook Type Personal
Computer External Output Signals
When a notebook type personal computer is connected for use in
projecting, a certain amount of knowledge is necessary for cable
connection, startup and the succeeding operations. Please refer to
the instruction manual of your notebook type personal computer
when performing the following operations.
1. Make sure that this device is receiving signals
from your notebook type personal computer.
The external signal may not be output even though the LCD
screen of the notebook type personal computer indicates such
output. Check by using the INFORMATION menu displayed
by this device (page 20, 21).
If 0kHz is displayed, there is no external output signal from the
personal computer.
2. If the notebook type personal computer is not
outputting the external signal, perform the fol-
lowing operation.
For IBM PC/AT machines, press either the [Fn] key or one of
the [F1] - [F12] keys.
Note
When displayed on the LCD screen of a notebook type personal
computer and this device at the same time, the projected video
may not be correct even the LCD screen display is normal. In
such case, turn off the notebook type personal computer display
and try using only the external output mode. (In some cases,
external output only can be set by performing step 2 above or by
closing the LCD panel.)
