Deploy the application and verify multi-monitor settings

The ScaleForResolution parameter becomes particularly important when you develop an application on a single monitor system that is intended to run on a multi-monitor system. The value assigned to the ScaleForResolution parameter determines whether the application can be scaled when moved from one environment to the other.

Important: It is recommended that you make a backup copy of the application before moving it to an different environment.

For example, if an application is developed on a computer with a single monitor with a resolution of 1024 x 768 and is intended to run on a system with four monitors in a side-by-side configuration with a total resolution of 4096 x 768, this requires an application conversion.

When you deploy the application on the multi-monitor system, a message appears prompting you to convert the application.

If the ScaleForResolution .ini setting is configured, you still see this message but the application is not converted and can then be run as designed. Select Yes to continue startup.

If the .ini setting is not configured, the InTouch HMI converts and scale all of the graphics and windows in the application to the new resolution. Doing so stretches and enlarge all windows and graphic displays, thus creating some unwanted results.

Important: Make sure that the multi-monitor Win.ini parameter settings are also configured on the destination computer before running your application. Win.ini settings do not automatically transfer with an InTouch application.
