Microsoft Details DPI Scaling Enhancements In Windows 8.1

Windows 8.1 DPI Scaling

Microsoft today detailed the DPI scaling enhancements that will be coming as part of Windows 8.1. Windows 8 not scaling appropriately  to very high resolution displays was one of the most discussed issues in the reviews, and Microsoft has fixed it now.

Windows 8.1 DPI scaling improvements are primarily focused on:

  • Optimizing the usability and readability of high-DPI displays
  • Providing a uniform experience multi-display systems
  • Empowering developers to optimize app-specific scaling based on display DPI

Here are the some challenges that we face when using Windows 8 on high resolution displays,

While high-resolution displays are amazing they also present some practical challenges. When you increase resolution you inherently decrease the size of each pixel (assuming same display size). By decreasing the size of each pixel the content shown on the display appears smaller. When display Dots-Per-Inch (DPI) gets sufficiently dense this “shrinking effect” can make content hard to see and UI targets difficult to click/tap.

Another challenge that is presented with the introduction of ultra-high resolution displays is dealing with multi-mon configurations with non-uniform DPI values. For example if you are running two 27” displays with one at full-HD and one at WQHD the content will not appear at the same scale when an app is moved from one display to the other. This is not an ideal user experience.

With the recent proliferation of high-DPI tablets, notebooks, and external displays these high-DPI and DPI scaling issues became an important consideration for Windows 8.1.

    Windows 8.1 (Blue) = innovation, innovation, innovation and even more innovation.

    I really hope that this yearly update will be implemented, this was what Microsoft envisioned with Windows XP but didn’t do, I would love to pay small fees for O.S. improvements rather than hundreds of Euro’s for a whole new O.S. that may or may not remove some of my most beloved features, as Windows Vista did to Windows XP and they had to re-implement it back into Windows 7, but removed the what are now known as Windows Essentials.

    I hope that they’ll bring back the Windows Essentials as pre-installed desktop apps with Windows 8.2

      I hope that’s where they’re headed. I’d even like to see then have 2 teams working on these updates on a tick-tock cycle – 1 releasing updates to the metro system with a focus on tablets and touch devices, and one developing improvements for the desktop side.

      I feel like its been a long time since any improvements were made to the desktop (except maybe better multi-monitor support). There are heaps of improvements I could think of that the desktop needs, including bringing those applications that you mentioned back.

      Another idea I had was that they should implement a way for any metro app to be run in either fullscreen metro mode, or on the desktop (kind of like the modernmix app from stardock). They could then add a store feature so that developers could upload a second version of their app with a different mouse and keyboard oriented UI. Or they could just upload a desktop app if its something like photoshop which is only suited to that environment. It’d be great to see desktop versions of xbox music and other Microsoft built apps. This would allow users to stay 100% in their preferred environment – desktop for mouse and keyboard users and metro/modern for touch users.
