The new iPad has a Retina display and is being raved about by the users. The 2048×1536-pixel 9.7-inch display on Apple’s new iPad has a 264 pixels-per-inch density.
David Washington, a senior program manager at the Microsoft, addressed the new iPad’s screen and discussed their upcoming tablets with dot-per-inch (DPI) in Microsoft’s Building Windows 8 blog.
He wrote that in the case of iPad 2 compared to new iPad, the 200 per cent scaling factor means that what you see on 1024×768 is exactly what you see on the new resolution, only sharper because more pixels are used.
The salient features in Washington’s post mentioned are:
- 135 DPI and up: Many Windows 8 tablet PCs will have pixel densities of at least 135 DPI. The “HD tablets” will have 1920×1080-pixel resolution on an 11.6-inch screen, packing a pixel density of 190 DPI, and “quad-XGA tablets” with 2560×1440 pixels on an 11.6-inch screen. The latter has a pixel density of 253 DPI.
- Scaling: apps in Windows 8 can fill the available space by bringing in more content. A developer can build the same app to show more content as the screen size shifts from a tablet to a large desktop monitor. Washington wrote that one way that Windows 8 helps app developers to adapt their apps for a variety of screen sizes is through support in the app platform for standards-based adaptive layouts. He says that just because more content can fit on screen this doesn’t mean every app will make use of this space
- Minimum screen resolution: Microsoft chose 1024×768 as the minimum. That is large enough to support rich layouts with Metro-style apps. Lower resolutions, like 800×600 for example, require simpler more basic layouts with less content. And, today, websites are usually designed for 1024×768 as the minimum resolution.
- Minimum screen resolution and “snap”: the resolution that supports all the features of Windows 8, including multitasking with snap, is 1366×768. Washington posted that this resolution was chosen as it has enough horizontal pixels to fit the 320px width of a snapped app, next to a main app with a 1024px width.
