I've just upgraded a Toshiba Portege adaptable tablet laptop which has now gone from Windows 7 to Windows 10, having started out as Windows XP.
When you twist and flip the monitor to use it tablet mode, the screen still automatically rotates to portrait aspect. If you want to watch movies, and/or flip the landscape aspect 180 degrees instead in tablet style, the method is very similar to Windows 7:
- Either right-click or press and hold the touchscreen pen to the desktop background until the small pop-up menu appears.
- Select 'Display settings'
- In the Settings window, click/tap the dropdown menu under 'Orientation' and select either 'Landscape' or 'Landscape (flipped)' depending on which way up you want to view your screen.
- Select 'Apply'.
- Confirm when prompted that you want to keep these settings until next time, or allow the settings to revert automatically within 10 seconds if it is the wrong one selected. The automatic screen aspect is not affected when you confirm 'Keep' and will still correct itself when you manually twist and return the screen to the laptop working position.
- Close the Settings menu at the top
You can change these display/screen orientation settings at any time with the laptop screen in any manual position according to your preferences.
You can also access this control in laptop mode from the 'Start' menu and select 'Settings' and click on 'Display' from the Settings home screen.
If you want, once you are using the Portege M400 as a touchscreen tablet, you can also change the Tablet Mode settings in the same Settings>Display control menu to display your app icons and hide the taskbar, depending on your most useful layout at the time. Simply switch on 'touchscreen friendly' and 'hide taskbar' then 'apply'.
Again, you can change this back when you wish. In contrast, the touchscreen-friendly app layout desktop setting does not detect when the screen is twisted back to laptop position and reset manually - to return to your normal taskbar display desktop with the apps hidden in the Start menu, go back to the Tablet Mode settings and change them back again.
