The team building Windows 8 demonstrated today how the upcoming operating system will support displays with various forms, resolutions and even high pixel density factors, so every application built using the Metro-style can be of high quality.
According to Blog.MSDN, Windows 8 is developed with the purpose of offering customers a broad choice of form factors while providing a polished and predictable user experience and enabling developers to easily program applications that look great on every screen.
First of all, the minimum desktop resolution was chosen to be 1024 by 768 pixels. This number includes a very large percentage of the existing screens and resolutions lesser than it will cause some application layouts to be truncated or run with low quality. To support any kind of Windows 8 Metro app, including the Snap mode, the screen will have to be compatible with resolutions above 1366 by 768 pixels.
In case of larger screens with higher resolutions, the content ratio will be preserved while the number of accessible content will be increased. Some applications will also have an adaptive layout, which can be enlarged on bigger displays.
Windows 8 also contains a scaling feature that enlarges content on high-density displays with three levels: 100 per cent when no scaling is applied, 140 per cent for HD tablets,180 per cent for quad-XGA tablets capable of 2560 per 1440 resolutions, or even resolution-independent resizes that will work will all screens. As a comparison, the iPad tablet uses a 200 per cent scaling solution.
