Introduction

This article relates to Cisco TelePresence System EX90.

Q. My computer is connected to the DVI-I input of the TANDBERG EX90, but the desktop is not displayed on the screen. Why?

A. There can be several reasons to this:

The EX90 input source is set to DVD

If both the DVI-I/PC and HDMI/DVD inputs are connected, make sure the input source is set to PC.

1. Tap the Adjustments icon in the bottom left corner on the inTouch main menu.

2. Select Settings > Source and set the source to PC. Note that the Source selector icon will only be visible if both input sources are connected.

The EX90 fails to detect the DVI-I input source type

The DVI-I input of the TANDBERG EX90 is capable of reading both digital and analog input signals. The EX90 will auto-detect the signal type by default. However, in some situations, it may be necessary to manually set up the EX90 to the correct input signal type.

1. Tap the Adjustments icon in the bottom left corner on the inTouch main menu.

2. Select Settings > Display settings and set the DVI Mode.

The computer does not support the resolution

The computer is not capable of outputting any of the supported input resolutions defined on the EX90.

The computer graphics card does not have the latest driver installed

The cables are not connected properly
