FAQ: Does WinCC OA Support Multiple Monitors

Back to All Topics

WinCC OA supports up to 18 monitors and it is easy to configure. Here is an excerpt from the WinCC OA help files, regarding feature/function. The multi-screen configuration allows configuring user-specific settings for the used screens (multi-monitor mode). These settings are:

  • Selection of the default template with a preview for all screens
  • Individual configuration of each screen (template selection, resolution, start panel selection)

You can configure the screens at two different points in time and for different purposes:

  • Before login – for the user logging in
  • In the template settings – for specific users

During runtime, you can quickly move panels between different monitors.


Licensing requires only one UI manager to support up to the 18 monitors.
