DPI awareness is essential for maintaining a consistent and visually accurate user interface. It ensures that all Ul elements automatically scale proportionally according to Windows display scaling settings, providing a clear and well-balanced appearance across monitors with different resolutions and DPI values.
In the following DPI scaling modes provided by Microsoft, PowerBuilder has optimized its DPI-aware scaling logic to work with the "Per-Monitor (V2) DPI Awareness" mode.
Which means, only the "Per-Monitor (V2) DPI Awareness" mode can benefit from PowerBuilder's optimization.
-
DPI Unaware -- (1) No scaling support, static at 96 DPI.
-
System DPI Awareness -- (2) Scales based on system DPI, but doesn't adjust dynamically for different monitors.
-
Per Monitor (V1) DPI Awareness -- (3) Scales based on the DPI of the monitor the app is on.
-
Per-Monitor (V2) DPI Awareness -- (4) Full dynamic scaling based on the monitor and window state.
-
DPI Unaware GDI Scaled -- (5) GDI scaling applied when running on high-DPI displays, but not ideal quality.
For more about automatic DPI scaling management provided by Microsoft, please refer to Microsoft's documentation: High DPI and DPI_awareness_context.
If you select the Per-Monitor (V2) DPI Awareness mode, the DPI scaling in your application will be handled by PowerBuilder together with Windows OS:
| PowerBuilder | Windows OS |
|---|---|
|
PowerBuilder will handle DPI scaling for the following UI elements:
|
Windows OS will handle DPI scaling for the following UI elements:
|
Note
If you select the other DPI scaling modes (such as System DPI Awareness, Per Monitor (V1) DPI Awareness), PowerBuilder does NOT provide additional optimization; and your application will rely entirely on Windows OS for automatic scaling.
Please run comprehensive testing to ensure that the scaling results meet your expectations.
