To disable the screen rotation on the M-Series, please follow the steps below:
1. Hold your finger down on a blank area of the desktop until a square appears (or right click with a mouse).
2. When the context menu opens, select Screen resolution
3. Deselect "Allow the screen to auto-rotate"
4. Select OK.
To enable the rotation again, please follow the same steps as above but select "Allow the screen to auto-rotate" in step three.
Note: If using Tobii Communicator, we suggest using the Landscape orientation since the Portrait orientation may cause text to appear misrepresented on some buttons.
