HTMLViewer.Renderer=Native shows webpages at 50% size on HiDPI Windows

Yup - that’s a massive overkill just to display some HTML content properly in HiDPI enabled Windows applications.

UserGuide: HiDPI Support:

[quote]Windows HiDPI Known Issues
HTMLViewer is not scaled on HiDPI screens.[/quote]

This is not entirely true… You can get HTMLViewer with Renderer: Native to show content with proper HiDPI scaling.

The workaround is to set the following Registry Value for the application (before first instantiating a HTMLViewer):

HKCU\\SOFTWARE\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_96DPI_PIXEL MyAppName.exe = 1

I’ve added this information to <https://xojo.com/issue/43991> along with an example project and ScreenShots.
Maybe Xojo will at least add that information to the HTMLViewer Documentation.

I don’t know what will happen on Windows 7/8/8.1… if someone cares to test, thanks :wink:
