Microsoft evokes the scaling in Windows 8, including for Metro applications.
Blog Building Windows 8 had remained silent since the launch of the Consumer Preview of the new OS from Microsoft. Or a new ticket has to be posted and a week after the launch of the new iPad and its screen Retina Display, Microsoft is... evokes the high screen resolutions.
The idea of Microsoft is to take advantage of uniformity in implementation around the Metro interface to unify the user experience. Whatever the definition of screen, Metro applications should therefore offer roughly the same ergonomics. In other words, it will not that elements are unreadable on the very high-definition screen of a tablet or take too much space on a monitor in standard resolution... While taking advantage of the high definitions to refine the display.
To do this, Microsoft will offer three levels of scale with Windows 8: 100% for a definition HD (1366 x 768), 140% for a 180% for a QHD (2560 x 1440) definition and definition Full HD (1920 x 1080).
Of course, the design of vector graphic elements is recommended, but many applications are still using elements whose size is not easily scalable, in contrast to the fonts that can be easily adapted. Remains that technologies - for some outcomes of CSS3 - will allow Metro applications to optimize their display based on the space available on the screen, and so for example to display more columns or rows of elements on a QHD screen on a single HD screen.
With and without scale...
However, Microsoft doesn't mention this management of display for the traditional Windows desktop which, reminder, is managed as an application in Windows 8.
