When the ArcGIS Pro graphics system detects a change in the computer's hardware configuration, the following error message appears: Changes in your graphics hardware detected. Close and reopen your map views to continue.
This message may display when your Graphics Processing Unit (GPU) drivers are updated, when your GPU fails or is reset by the driver, or when docking and undocking a laptop computer. When this occurs, ArcGIS Pro suspends rendering of the map views. You can close and reopen the map views to resume rendering.
If this error message appears frequently without your intervention, you may need to update your GPU drivers from the manufacturer's site.
