But how do we approach it? When building a DPI-aware application, firstly we must declare it as such, so the OS would know how to handle it. Windows has support for HDPI (high DPI) scaling. And the user can set a custom scale factor up to 500%. More scale factors were added as well-175%, 200%, 225% etc.

With Windows 8.1 came per monitor DPI scaling, which was improved by the Windows 10 Creators Update (1703). Windows 8 removed the numerical values and added some minor improvements. The OS also reads the monitor DPI and sets a recommended scaling. Windows 7 made DPI per user and enabled easier DPI switching with log off only. WPF has one limitation-it cannot scale hosted controls. DirectX and vector graphics is used for drawing their elements and scaling comes out of the box.
Applications designed with WPF natively support DPI scaling. There is also a global option to turn off the virtualization and use the old XP-style rendering. This would produce correct, but fuzzy rendering of the application.
If not, the OS will use DPI virtualization, which will render the application using a native 96 DPI as a bitmap and then scale the bitmap on the screen. An application can declare itself as DPI-aware and scale its own UI elements. Windows Vista introduced DPI awareness and DPI virtualization. When using it you should always be cautious and check if the result is better or not. It does not work flawlessly-it generally scales fonts and some graphics. Microsoft added some support for GDI/GDI+ scaling recently. Unfortunately, this would mostly make the text bigger in a high DPI setting, which was problematic. So how does Windows handle high DPI? Starting with Windows XP, Microsoft introduced the GDI+ library, which allows the scaling of fonts and some other UI elements. But if we are to scale our square by a factor of two on the second display, we will get our desired result. Our 4x4 pixel square looks quite smaller on the second display, where we have four times as many pixels as the first display. This means that if you draw a square of 4x4 pixels, it will look physically smaller on a higher DPI device than on a lower DPI device. Today there are many devices with different DPIs-there are many monitors with 200-300 DPI and smartphones going as high as 800 DPI. Then the OS draws the virtual screen to the physical one.

This virtual screen is used by the software to render its content on. The operating system creates a virtual screen with default DPI (let’s say 96). The solution is the concept of logical PPI. While the reasoning behind this comes from the 72 points per inch standard and Microsoft wanting to have 33% more space for better image and font drawing, you can imagine the problems that arose with the new monitors that support higher pixel density. When it comes to monitors the proper term is PPI (pixels per inch), but the two terms are mostly interchangeable today.Īt the beginning Microsoft Windows used a default display DPI of 96 PPI, and Apple/Macintosh used 72 PPI.

And finally we'll wrap up with some tips for designing scalable WinForms and an example. We will see how scaling works in WinForms. Then we will introduce the concept of DPI awareness and see the specifics for WinForms. We will go through the emergence of high DPI displays and how Windows handles high DPI. Let's dive into the specifics of high DPI and try to understand different problems that high DPI displays cause, and how to address them. In these days of high-density pixel displays, scaling is becoming an increasingly important topic. What is DPI? How is high DPI handled in Windows and WinForms? How can you scale WinForms apps today? Let’s explore the world of high DPI.
