Answer 1

You can get everything you need about the resolution using Window and DisplayInformation

var bounds = Window.Current.Bounds;
var displayInfo = DisplayInformation.GetForCurrentView();

Answer 2

When using the WinRT API, you can retrieve the screen resolution with Windows.UI.Xaml.Window.Current.Bounds (Height and Width).

You need to multiply those values by the scale factor to get the real resolution. You can retrieve the scale factor by calling DisplayInformation.GetForCurrentView().RawPixelsPerViewPixel

var scaleFactor = DisplayInformation.GetForCurrentView().RawPixelsPerViewPixel;

Debug.WriteLine("The current resolution is {0}x{1}", Window.Current.Bounds.Width * scaleFactor, Window.Current.Bounds.Height * scaleFactor);
