How to Manage Display EDIDs on Quadro and NVS Boards

This article applies to all desktop and mobile Quadro and desktop NVS boards on Windows XP, 7, and 8, as well as Linux.

With the R256 and newer display drivers, all Quadro and NVS boards have an integrated EDID management system accessible through the system topology viewer in the NVIDIA control panel. The management system provides an easy way to apply an EDID when the A/V infrastructure cannot provide the correct EDID. When an EDID is loaded, or forced, through the management system, the driver ignores display hot-plug actions.

How to Export an EDID (Windows)

Step 1: Open the NVIDIA Control Panel and click on View System Topology.

Step 2: Locate the display which you want to export and click the EDID link under it:

Step 3: In the EDID management window that appears, click Export EDID… and save the EDID. The NVIDIA control panel saves the EDID as a text file.
