In modern enterprise environments, it's common to use laptops with a default display scaling of **150%**, while external monitors remain at **100%**. This mixed-DPI setup—despite having the same resolution—causes WPF applications to behave inconsistently: - UI elements are resized unexpectedly - Text becomes oversized or blurry - Layouts break or overflow - Critical functionality becomes inaccessible This severely impacts usability, maintainability, and business productivity. --- ### Request: Please add a manifest setting or API that allows developers to **force WPF applications to render at 100% scale**, regardless of the system's DPI settings or PerMonitorV2 behavior. #### Suggested options: - Manifest tag: ```xml <dpiAwareness>fixed96dpi</dpiAwareness> ``` - API call: ```csharp SetProcessDpiFixed96(); // Forces 96 DPI rendering ``` - Windows setting: “Allow apps to ignore display scaling” toggle for advanced users --- ### Why this matters: - Current DPI Awareness modes (`system`, `perMonitor`, `perMonitorV2`) do not allow full control over rendering scale - Even with `SetProcessDpiAwareness()` or `SetProcessDPIAware()`, Windows 11 still enforces DPI scaling when dragging windows between monitors - Developers have no reliable way to ensure consistent UI rendering across mixed-DPI environments --- ### Impact: This issue affects thousands of enterprise applications and users globally. It causes visual inconsistencies, functional errors, and user frustration—ultimately hindering productivity and contributing to economic inefficiency. ---
