Windows will send DPI notifications to top-level windows in the application so that it can redraw when the DPI changes. For more information, see the Configure Windows to fix blurry apps section in this article.Īpplication is bitmap stretched when moved to a new display with a different DPI.Īpplication is capable of redrawing itself correctly when the DPI changes. ModeĪpplication always renders as if it is on a display with a DPI value of 96.Īpplication is bitmap stretched to expected size on primary and secondary displays.Īpplication detects the DPI of the primary connected monitor at Windows login but cannot respond to DPI changes. For more information about the DPI awareness modes, see High DPI Desktop Application Development on Windows. This is a simplified description of the modes to explain how Office solutions support them. Each DPI awareness mode supports different capabilities, as described in the following table. Throughout this article we’ll refer to the DPI awareness modes that Windows supports. The following types of Office solutions can be affected by DPI scaling: Fonts and images appear too small, too large or in the wrong location.Elements such as buttons and labels appear in the wrong location in your solution’s window.The windows draw in the wrong location or have incorrect sizing.If your Office solution is adversely affected by DPI scaling, you will see one or more of the following symptoms: This happens in scenarios such as dragging an application to a different monitor or docking your laptop. Windows applies DPI scaling when an application is moved from one display to another display with a different DPI. This article describes how Office supports dynamic DPI, and what steps you can take to ensure the best viewing experience for your Office extensibility solution to handle DPI scaling. However, your Office solution must also respond to changes to draw correctly when the DPI changes. Office 2016 applications, such as Word and Excel, have been updated to respond to changes in scale factor. Applications that don’t support DPI scaling might look fine on low DPI monitors, but will look stretched and blurry when shown on a high DPI monitor. This requires applications to adjust when the user moves the app to a monitor with a different DPI, or changes the zoom level. Many computer and display configurations now support high DPI (dots-per-inch) resolutions, and can connect multiple monitors with different sizes and pixel densities.
