Full screen mode is a function that allows you to use the whole screen. Thus you can watch your stream with no further display content. This is especially useful on the iPhone because of the smaller screen.
Enable full screen mode
To enable full screen, please use the option screen rotation. Rotate your iPhone so that it is in landscape mode.
You can additionally zoom the image by double tapping the picture. This is especially useful for shows that are transmitted in 4:3.
Exit full screen mode
Turn your device back to portrait mode.
Full screen doesn't work?
Please check whether the portrait orientation lock is off. Otherwise full screen cannot be enabled. You can deactivate the portrait orientation lock in the control center of your device. From any display, swipe up to open the control center. If the portrait orientation lock button is activated, please deactivate it by tapping on the icon. Once you are done, try again. Zattoo should be streaming in full screen now when you rotate your device to landscape.
