How to detect/find Windows 8 current scale percentage

Question

There are three scale percentages in Windows 8: •100% when no scaling is applied •140% for HD tablets •180% for quad-XGA tablets

How can I detect in WinRT code what percentage the screen is at that moment?

(I want to make a custom image service that loads the best resolution from a database)

Answer 1

Use

var currentScale = DisplayProperties.ResolutionScale;
