Vector Applications on High Resolution Displays (4k Resolution Monitors)
Having a high resolution display (e. g. 4k resolution monitor), there might be some HiDPI issues on Windows 10, e. g 
- Elements such as applications, the taskbar, icons, toolbars, text, and dialog boxes appear to be fuzzy.
- Elements are too large or too small compared to the rest of the desktop.
- Blurry text appears in applications or in the Windows interface.
Adjust the scaling manually – system-wide:
- Right click on your Desktop and choose Display Settings from the context menu. Alternatively you can go to the Windows Start menu and choose Settings | Display.
- Then adjust the custom Scale and Layout for your display by choosing the Resolution and Change the size of text, apps and other items. Please be aware to choose a resolution equal to your display’s native resolution. Otherwise texts and images will get blurry.
Disable the scaling for specific applications only:
- Right click on the executable (*.exe) of the specific application, that causes the DPI issues, e. g. hexview32.exe, canape32.exe, CANoe64.exe, CAPLBrowser.exe, then choose Properties from the context menu. Go to the Compatibility tab and Change High DPI settings.
Then enable Override high DPI scaling behavior. Now, there are two options available: Scaling performed by …
This is the standard way Windows 10 will handle the scaling. Windows will stretch the interface and bitmap elements, text may be blurry.
Depending on the Window 10 Version, the text for this setting may be different. In Windows 10 Version 1703 and later version of Windows, the option is called Override high DPI scaling behavior, scaling performed by: Application. In older versions, it is called Disable display scaling on high DPI settings.
This option will force the application (e. g. CANape, CANoe) to take care of the scaling.
- Confirm the settings with OK and then Apply.
Please be aware, that these solutions only mitigate the issues.
