Introduction

This document describes how to ensure that the Video Graphic Display is correct in Webex on the Windows 7 or 10 platforms.

Problem

In a Webex, when you start your web cam, the video for all participants does not display correctly and appears cut off.

These images display the problem.

Solution

Confirm that the Windows 7 or 10 system uses the NVIDIA graphic card:

1. Navigate to Start>Run.

2. In the Open field type, DxDiag, and select Ok.

3. The DirectX Diagnostic Tool opens.

4. Select each display tab for each display monitor.

5. In each display tab, search in the Device field to ensure that the NVIDIA Graphic Card is listed.
