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.
