You are developing a Universal Windows Platform (UWP) app that will support two displays. The primary
display will have a maximum resolution of 1080 p. The secondary display will support a maximum resolution of
4 К and will not support interactivity.
Your need to ensure that the app can use the full resolution of each display.
What is the best approach to achieve the goal? More than one answer choice may achieve the goal. Select the
BEST answer.
A.
Set the AutoSizeMode property for the app.
B.
Enable multiple display support by using the ApplicationView API.
C.
Enable multiple display support by using the ProjectionManager API.
D.
Set the AutoScaleMode property for the app.
Explanation:
Projection manager lets you project a separate window of your app on another screen.
When the second window is for display only, not for interaction then it is recommended that you use the
projection manager.https://msdn.microsoft.com/en-us/library/windows/apps/dn495078.aspx
By default, without using the projection manager, if a user connects to another display device, the app window is duplicated on the 2nd screen. When in duplicate mode, Windows automatically picks a resolution that works for both screens instead of using the screen info for the external screen, but this resolution might not be ideal for video playback or gaming. When you use the projection manager, Windows retrieves the resolution and the aspect ratio of the projection screen and optimizes the window display.
