The zooming functionality has to be set for each used screen window. Kind regards Stefan

The solution suggested by @PedriDias009 is right but is only valid for screen windows. I need to disable the zooming for the entire screen instead: checking the screen properties (not screen window..) there isn't the option to disable it (which screen window has). I also checked in runtime properties but there is nothing about it. Anybody can help me? Is the only way to write a cyclic script which always force the zoom factor at 100%? Hope it doesn't! Many thanks in advance.

To work without zooming, you must change this property for each screen window. However, there is also an internal screen window, the root screen window. As of WinCC Unified V18 Update 1, the properties of the root screen can be accessed via the screen management, but due to a bug this has no effect on a Unified Comfort Panel. So in case of a Unified Comfort Panel you have to use scripting. You can add the following code to the OnLoaded event of the start screen to disable zooming for the root screen: UI.RootWindow.InteractiveZooming = false; Kind regards Stefan

Peux-tu mettre des photos stp ? Hello If you use a startscreen that is always open for example where your screen windows are located for navigation and header and content, you can run this script in the Loaded event of the screen. Or in the newer Unified Versions you can set this in Screen Management -> Maini Screen Windows-> create the main screen and set : (But Use the latest Update!) Bye Murof

EmilioSantos (translated by DeepL) Good morning, I am looking for the Zoom-Enable option but it does not appear in V19. Does anyone know why? I show an image of what I get in the section. Thank you. You are looking for the property on a screen, but it is a screen window property. Kind regards Stefan

You could also pass these parameters to your explorer executable if this is Unified PC Runtime. chrome.exe --kiosk --incognito --disable-pinch --overscroll-history-navigation=0 --disable-pinch disables pinch zoom. More info on the page: https://stackoverflow.com/questions/22999829/disable-chrome-pinch-zoom-for-use-in-kiosk
