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:
- Navigate to Start>Run.
- In the Open field type, DxDiag, and select Ok.
- The DirectX Diagnostic Tool opens.
- Select each display tab for each display monitor.
- In each display tab, search in the Device field to ensure that the NVIDIA Graphic Card is listed.
- If so, the root cause is the Graphics Processing Unit (GPU).
- Next, improve the NVIDIA Graphics Card performance and boost the Frames per Second (FPS).
