Multi-Monitor & High Resolutions (4K)

Modify C:\Users\<UserName>\AppData\Local\Wonderware\win.ini to add the following settings under the [InTouch] heading

MultiScreen=1
MultiScreenWidth=3840
MultiScreenHeight=2160

Without the above the screen will not span across monitors. Resolutions will need to be adjusted accordingly, but the above is an example using 4 1920x1080 monitors arranged in a 2x2 grid. This configuration change also is required when using larger resolutions such as 4K. For instance the above configuration changes were required on a deployment with thin clients using 4K televisions even though they were single monitors, the graphics would not display correctly without this change.
