NVIDIA Surround is a feature that allows multiple monitors to be reported to Windows as a single larger monitor. This allows programs to utilize true Fullscreen mode and still span multiple physical displays.
First it is very highly recommended that you use 3 monitors set at the same resolution. It is recommended, but not required, to have three monitors of the same make/model, though screens that are the same size will work.
Step 1: Ensure Compatibility
|Confirm that your graphics card has enough ports of the right kind to support your monitor setup.|
For example some cards may have 1xHDMI port, 1xDisplayPort port, and 2xDVI ports, making connecting three identical monitors difficult.
Step 2: Update Drivers
|Before configuring Surround, perform a clean installation of the latest version of graphics card drivers. This can help to prevent some issues from occurring.|
Note: Clean Install is a checkbox in the Custom installation process. This should be checked to ensure no old setting interfere with the Surround configuration.
Step 3: Navigate NVIDIA Control Panel
|Right click on your desktop background and select NVIDIA Control Panel from the context menu.|
Inside the NVIDIA Control Panel, select Configure Surround, PhysX
Step 4: Open Surround Configurator
|On the Configure Surround, PhysX page check the box for Span displays with Surround and then click the Configure button below it.|
Step 5: Define Monitor Layout
|A new window will pop up showing all connected monitors. There are three columns at the bottom containing settings.|
The Displays column shows the monitors available for selection. Check the boxes for each monitor you want to include in the merged display. Use the dropdown to determine the orientation. If your monitors are out of order you can click and drag them to reorder.
The Resolution column defines the size and refresh rate of the merged monitor that will be created. Typically these should both be set to the highest values available in the lists.
The Bezel Correction settings are for power users and should not need to be adjusted for most users. iRacing performs its own bezel correction before pushing the image to the merged monitor so the values in this menu are redundant and can make the image appear incorrect.
Finally, select Enable Surround. Your displays will flicker for a moment and then should come back in the requested mode.
Step 6: Run the iRacing Graphics Config
|The merged monitor will now be seen by the iRacing graphics config tool, as well as by the sim itself. You may rerun the graphics config tool to make sure settings are correct for this new setup. |
This can be done through the UI by clicking the helmet in the top right, selecting Settings, and then clicking Graphics Config.
