Universal App Screen Resolution

Question

Ok, what's the best way of getting the screen resolution on a WP8.1 device.   I've tried this

http://msdn.microsoft.com/en-us/library/windows/apps/jj247549(v=vs.105).aspx

and I get a deprecation warning

warning C4973: 'Windows::Graphics::Display::DisplayPropertiesEventHandler' : marked as deprecated

1>          Message: 'The DisplayProperties type and related event handlers may be altered and or unavailable for releases after Windows 8.1. Instead, use DisplayInformation.'

Answer 1

Hi Pappaxray,

Why not use DisplayInformation instead? The documentation you read is only workable for WP 8.0 but not 8.1.

RawPixelsPerViewPixel | rawPixelsPerViewPixel property could help you I think.

Answer 2

I tried DisplayInformation but I believe RawPixelsPerViewPixel only exists for the windows phone version.  Is there a way of doing this for both Windows and Windows Phone versions without resorting to platform specific code?

Answer 3

Sorry, the answer is no, there is no way that can work both for Windows Store App and Windows Phone.

Answer 4

Its not that much platform specific code,

var bounds = Window.Current.Bounds;

double height = bounds.Height;
double width = bounds.Width;

#if WINDOWS_PHONE_APP
     height *= DisplayInformation.GetForCurrentView().RawPixesPerViewPixel;
     width *= DisplayInformation.GetForCurrentView().RawPixesPerViewPixel;
#endif
