Table 1 on the next page lists the various Macintosh models and the
possible switch settings. If your Mac is not listed here, please select
the model closest to it.

Select a column that has an ”X” in it, and refer to Table 2 to check if
your monitor supports the resolution(s) listed. Then, select a switch
setting that both your monitor and your Mac can support.

Settings B, H, and I in Table 1 and 2 are multimode settings, the
others are fixed mode. This means that you can change resolutions
in the Macintosh Apple®Menu under “Control Panel/Monitors”
without having to restart the computer. In “Control Panel/Monitors”,
more selections are available on many Mac models by pressing the
“Option” key on the keyboard while clicking on the “OPTIONS” button
on the screen.

Note: Restart the computer each time the rotary and switch

settings are changed.

The ON position in the DIP switches is the “up” position.

The first setting, “3 / All off”, is a fixed-mode setting. It is the only
setting that will work with the Mac IIci and IIsi. Older non-SVGA
monitors cannot support the resolution this setting produces.

SETTING THE SWITCH POSITIONS

DIP SWITCHES

Switch Descriptions

1. The rotary knob and DIP switches 1, 3, 4, and 8 set the

resolution of the monitor and computer.

2. DIP switches 5 and 6 set external sync. For Mac IIci, IIsi,

IIvi, IIvx, or any computer that uses “sync on green”, these
are to be turned OFF. For all other computers, they are to be
turned ON.

3. DIP switch 7 is composite sync and it is rarely used. Try

turning it on and observe if it improves results.

TROUBLESHOOTING

There is no image, or the image has no vertical hold.

1.

The monitor and the computer are not synchronized correctly.
Try changing the settings of both DIP switches 5 and 6, or just
DIP switch 7.

2. The monitor does not support the resolution selected.

Try changing to a different switch setting, and then restart
the computer.

There is no color in the image.

This is most likely caused by changing switch settings while the
computer boots up. Go into the “Control Panel/Monitors” in the
Macintosh Apple menu. Select the color depth you prefer, and
click “OK”.

The image is too small on the screen.

1.

Adjust the screen size by using the controls on your monitor.

2. If the monitor cannot expand the image to fit the entire screen

using its controls, the monitor simply cannot support that
resolution. Try switching to a lower resolution.

If your question was not answered here, please e-mail your
question to [e-mail] or call Belkin Technical Support
at 310-898-1100 ext. 2263.

Before calling, please ensure that you have all of your
equipment connected and powered ON, and that you are
at the computer.

Your Belkin VGA Adapter is capable of either “multimode” or
“fixed-mode” settings.

Multimode settings allow you to change resolutions anytime
through the Control Panel/Monitors in the Mac OS®, without having
to restart your computer. A MultiSync monitor may be required for
some settings, depending on which Mac OS and Mac computer you
are using.

Fixed-mode settings, unlike multimode, keep your monitor on one
resolution. In order to change resolutions once fixed-mode is in
effect, you must change the settings on your VGA Adapter, and
then restart your computer.

Finding Other Multimode Settings

To find other settings supported by your Mac, review Table 1.
Note: For example, the Mac LC II has an “X” in columns A and B.

Look in Table 2 for rows A and B. There, you pick your preferred
setting. Setting B is more desirable than A because it is a
multimode setting, and allows you more flexibility in choosing
resolution settings. Be sure your monitor supports the settings you
wish to use before proceeding.

Set your VGA Adapter’s rotary knob on 0 and all the DIP switches
OFF, except 8, as described on setting# B in Table 2.

Restart your computer. You will have the multimode selections in
your Mac Control Panel.
