Windows 10 display?

[awa355]

A new laptop with windows 10 installed occasionally switches from landscape display to portrait. I got it back to landscape by hitting one of the F buttons but can't find which one this time around.

Have just got it back to landscape (somehow) but it is only 2/3rds of the window. width wise. Any advice? apart from Akzle's.

Don't have Win10 running, but in Win7, Ctrl+Alt and Arrows (Up down left right) controlled the orientation of display.

For font/resolution size, you should be able to right click on the desktop then choose Personalise/Screen resolution etc, or failing that, try clicking on Start then type resolution or display... as said, these are approx guesses.

Depending on the laptop, there are possibly hot keys to change the display... I turn them off for clients for your very experience
