How to set up a 3 screen display using 2 nVidia GTX graphic cards

Open the nVidia control panel

Under 3d settings select “Configure SLI, PhysX, Surround”

Select “Span displays with Surround”

Select “Configure”

You will need to configure the monitors so that the left monitor will display the Windows START button  and the right monitor will display the time

on the desktop.

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 1200 x 1920, multiply 1920 by 3 and enter that number 5760 on the line Fullscreenwidith=

Press SAVE

Open up your Renderer.ini file (also located in your My Documents/iRacing directory) and change the number of screens to 3. Press SAVE

Log onto a test session, if any other graphic changes need to be made select Options then Graphics tab
