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.)
