How to make the most of Windows Phone's HD screen

Nokia recently released two models of 6-inch large-screen handsets: Lumia 1520 and Lumia 1320. In order to support this device WP upgraded the OS GDR3 supports 1080P HD resolution (1520), although GER3 is provided backwards compatible, of course GDR3 also supports features to support 1080P high-definition screens.

All the discussion code implementations are here

Windows Phone 7 is beginning to implement the unified resolution specification WVGA (480), which is generally applicable with 3.7-4.3 inch screens. The Windows Phone 8 extension supports multiple resolutions (3 kinds) WVGA,WXGA (768 x 1280), and 720P (720 x 1280), but the physical dimensions they support are mostly between 4–4.5 inches, and no matter what resolution the application is running on the machine we are Is the adaptation from the base resolution (480 x), for example, 720P resolution, the screen's width and height ratio is 16:9, it will be 1.5 times times magnification from the base resolution, but because of the aspect ratio, the actual scaling before the resolution is 853, the height of 53 pixels to adapt to 720P resolution. In addition 768 x 1280 and the base resolution of the screen is 15:9, so you can zoom directly to a 1.6 screen.

With the release of Windows phone 8 's GDR3, not only does a (1920 x 1080) HD resolution join, but it also brings some and big screens to the phone compatibility issue. For example, an identical page is displayed on a 3.7-inch screen and is displayed on a 6-inch device with different effects, and a user experience.

In theory, Windows Phone may run on a larger (7 ") screen device, so we make full use of the screen when we need it, at least in the application to know what resolution we are currently in, but if we do nothing, the system will help us with a 720P Application adaptation (for compatibility with existing applications), that is, scaling from the 853 x, but he is not simply scaling from 720P to 1080P, the system will render all controls from the new rendering to the 1080P device.

So our existing app can continue to run on 1080P devices without impact, but what can we do to better fit a 1080P device for a new application? For example, when the current device was detected to be a fit for the video we played when the 1080P was supported, a pair of new detectable attribute parameters were supported in the GDR3 SDK.
