Preview on a small screen

Hi guys,
I have a 16" macbook and I am producing for a 55" (3840x2160) screen. How do I scale the preview window to be able to see the entire screen?



Have you tried changing the resolution in game settings?

No, the resolution of the game must be 3840x2160, since that’s the size of the touchscreen where the game will run.

So you have set the resolution in the game settings to 3840x2160?

This is 16:9 aspect ratio, so you could choose a lower resolution that’s still 16:9, and put the game in full screen mode.

Since It is a big touch screen, the players will be standing really close to the screen, watching video and reading small text etc, so I really would like to have high resolution.
