In a blog post, Microsoft says the new high-DPI scaling improvements in Windows 10 will make multiple monitor setup for different resolutions easier. For users who run a desktop application that does not render on high-DPI displays, there is now a solution. Windows 10 Creators Update will run the application as a DPI-unaware process. Essentially, this means users can choose the new functionality in several options, as detailed below:
Application: This setting defaults the app to a per-monitor DPI awareness. Users may recognize this ability as it was previously known as “Disable display scaling on high-DPI settings.” System: Windows’ standard procedure, this will bitmap stretch the UI during DPI changes. System (Enhanced): GDI Scaling
From those options, System (Enhanced) is a new addition coming with the Creators Update. It allows texts and primitives to render more accurately on high-DPI displays. However, this is only relevant for GDI-based apps. Windows 10 can DPI scale these apps on a per monitor basis. One of the main issues of DPI scaling on Windows 10 has been the inability to see desktop apps in scale when in extended display mode across multiple displays. Microsoft says Creators Update solves this issue.
DPI Scaling in the Anniversary Update
The Windows 10 Creators Update may finally see Microsoft get DPI scaling right on its platform. I wrote last year that accurately scaling across multiple monitors has been an issue for Windows for years. Despite passing through Windows 7, 8, and 10 in the last decade, the company has still not cracked DPI scaling. Last year’s Anniversary Update attempted to address the problem. Improvements were made, but still users were still not entirely happy. Hopefully Microsoft is going to please more people with changes in the Creators Update.
