How to set up a 3 screen display using nVidia GTX graphic cards

First you will need 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. It is NOT recommended to have three different sized screens as it will be difficult to get the screens to line up properly and could lead to side effects like headaches, motion sickness, ect.

Certain NVIDIA cards can support 3 displays using a single NVIDIA graphics card. Plug in all monitors to the NVIDIA graphics card and be sure that they are connected.

Make sure to download the most up-to-date drivers for both your graphics card and your version of Windows (7, 8, or 10 — make sure to select the 64-bit option if you’re on a 64-bit version of the OS).

Configuring your monitors

To get to the configuration window in Windows Vista, you first have to open the Control Panel, then click "Appearance and Personalization,” then "Adjust screen resolution.”

In Windows 7 and 8 just right-click the desktop and click on "Screen resolution.”

In Windows 10, right-click the desktop then click "Display settings.”

If any of your monitors are blank or mirrored, click on them, select "extend desktop to this display,” then click "Apply.” you can now use all your screens to display programs.

Now it’s time to fine-tune your setup: click on each monitor and make sure it’s set to the recommended resolution (usually the highest one available). If you’ve set any of your monitors in a portrait (vertical) orientation, you can adjust the rotation in the Orientation drop-down menu. You can also drag and drop the monitors in the top of the window to match their physical location of your desk, both vertically and horizontally – if one of your monitors is a little lower than the other, slide it down a notch or two on the screen. Click "Identify” if you’re not sure which screen goes where.

Finally, click the center monitor (or whichever one you intend to be your "primary” screen) and click the box marked "Make this my main display.” This is where your Start menu, desktop icons, and program buttons will appear. Click "Apply” to see if everything is working, then adjust as needed.


Once all 3 screens are all showing up in windows you can now open up the NVIDIA Control Center by right clicking on the desktop and select NVIDIA Control Panel.

Under Display, click "set up multiple displays”

If you need help setting up the displays, you can get step by step instructions from NVIDIA's Support Page

Once this is done, open up the app.ini file (located in your My Documents/iRacing directory).

Take the resolution width and multiple it by 3. Example: If your screens were 1920 X 1080, multiply 1920 by 3 and enter that number, 5760, on the line fullscreenwidith=

Then click File, then click on Save. Next, open up your Renderer.ini file.

FindNumMonitor= and change the number of screens to 3.

Then click File, then click Save. Finally, Log onto a test session, if any other graphic changes need to be made select Options then Graphics tab.
