6 Troubleshooting

1 Introduction

This DVI to VGA Converter is mainly designed to connect DVI-KVM Extenders local
outputs to traditional VGA KVM-Switches. Additionally they may be used to convert DVI
signals of a graphic card, to be displayed on a VGA monitor – especially on older,
expensive beamers etc. Depending on a strange behavior of some display drivers, it cannot
be guaranteed, that it will work (on first attempt, without modifications) on each graphic
card. For further information on this, please contact ‘Technical Support’.

2 Quick Setup

This section briefly describes how to install your DVI to VGA Converter. Unless you are an
experienced user, we recommend that you follow the full procedures described in the rest of this
manual..

1. Connect VGA monitor cable to Converter.

2. Connect DVI-D graphic source to Converter.

3. Connect p.s.u. to Converter.

4. Power up the system.

3 Installation

For first-time users, we recommend that you carry out a test placement, confined to a single room,
before commencing full installation. This will allow you to identify and solve any cabling problems,
and experiment with the DVI to VGA Converter more conveniently.

• Check the power supply.

• Your DVI Source provides a 1920x1200 resolution. VGA cannot display the 1920x1200

resolution, because this has a timing with no black shoulders. VGA monitors cannot detect the
synchronization signals, if there is no black shoulder.

• The DVI2VGA Converter has a built-in, virtual ‘Digital DDC’ to show the graphic

source, that a DVI monitor is attached. As there is no possibility, to translate
‘analogue DDC’ from the attached VGA monitor, this virtual DDC simulates the
presence of a DVI monitor.

Some mal programmed drivers have strange reactions to this DDC information: Some
do only display the preferred (native) resolution. Others do, if you have 1600x1200
for preferred resolution, not display 1920x1080 because 1920 is bigger than 1600. On
the other hand, if you have 1920x1080 for maximum resolution, it will not display
1600x1200 because 1200 is bigger than 1080.

Under some circumstances, it is helpful, to deselect ‚Hide modes that this monitor
cannot display’ in … ‘Graphic Properties’ – ‘Settings’ – ‘Advanced’ – ‘Monitor’

You should receive the following items in your converter package:

• DVI-D to VGA Converter unit

• 1x 5V DC universal power supply for the DVI-D to VGA Converter

• This manual

• CPU cable (1.8m) DVI-D video (DVI-D single link male) connector – DVI-D video (DVI-D

single link male) connector

3.2 System Setup

To install your DVI to VGA Converter:

1. Switch off all devices.

2. Connect the monitor to the Converter unit

3. Using the supplied CPU cable, connect the converter to your DVI-D graphic source.

4. Connect the 5V power supply to power the unit.

Only use the power supply originally supplied with this
equipment or a manufacturer-approved replacement.

5. Power up the system.

3.3 Interconnection Cable Requirements

To connect the Converter unit you will need:

• DVI-D: Please ensure, that you use high quality DVI-D cables, to attach the system to your

CPU. The length of the cable should not expire 1.8m (6ft). The device should also work with
longer cables . however this can never be guaranteed. To our experiences, lengths above of 5m
normally fail.

• VGA: Please ensure, that you use high quality VGA cables, to attach the monitor to your

Converter. The length of the cable should not expire 1.8m (6ft). The device should also work
with longer cables . however this can never be guaranteed. To our experiences, lengths above
of 20m normally fail.

5 Supported Resolutions

The Converter can handle all known DVI resolutions up to 1920x1080. Nevertheless, there is only a
selection of most common resolutions stored in the DDC (EDID) table. If the converter does not
show any picture on the VGA output, it may depend on a missing resolution in the table or a mal
programmed driver, which is not able, to use any other than the preferred resolution. In this case,
please contact Technical Support, to program a user defined DDC-table.
