Here is how to setup the NVIDIA Surround feature to have a continual display across multiple monitors with a NVIDIA graphics card.
1. Open the NVIDIA Control Panel by right clicking any empty space on the desktop.
2. On the navigation tree on the left, under 3D Settings, select the Configure Surround, PhysX.
3. On the Configure Surround, PhysX options, you will see a Surround configuration with a box labeled Span displays with Surround available. Click on it to check it. Once checked, a button or “Configure…” will appear right below. Click on that to bring up configuration for Surround.
4. The NVIDIA Set Up Surround window will come up. From here you can configure the monitor setup. By default, if you have three monitors in a row, you will want Topology at 1 x 3.
Otherwise each monitor will have a large number that will show up on each that will reflect what is showing on the settings. You will need to make sure you configure the display to how they are lined up (i.e. if the left monitor has 3, make sure the settings reflects that by dragging the monitor).
5. Once you have everything you need, click on the Enable Surround below. The displays will now stretch everything out to act like one monitor and you can turn on a game to play with the 3D Surround.
6. If you are finished with it and want to turn it off, you will simply need to return to the NVIDIA Set Up Surround and click on Disable Surround.
