Text Rendering in LabVIEW

I wish NI provided an easier solution for this. I'd trade Nigel for non-fuzzy windows and more modern and flexible controls.

If you're talking about the manifest, it's here in the Build Properties, and it seems to work, indeed:

So, the whole part about using mt.exe and Python/Rust code to embed the manifest is not applicable. There's a simpler solution (the manifest itself was shown in the comment above).

And, by the way, this won't be appended to the existing manifest; it will replace it completely:

good to know.

Cool! I did look through the Build Spec for a mention of manifest files, but didn't inspect the Security section thoroughly enough. I was thinking more along the lines of a checkbox in the build spec that says something like "handle HiDPI more gracefully", and which would put the relevant text into the manifest file. But this at least goes part of the way.

The manifest using PerMonitorV2 would require a lot of programming to have the app scale properly?

NI's recommendation is to set the Scaling performed by to System (Enhanced). Then you don't have to do anything in the code. Google tells me that this is the manifest for that:

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">
<asmv3:application>
<asmv3:windowsSettings>
<!-- Tells Windows that the app is not DPI-aware, forcing OS bitmap scaling so the UI doesn't become microscopically small -->
<dpiAware xmlns="http://microsoft.com">false</dpiAware>

<!-- Enables GDI scaling, which is the internal Windows name for the "System (Enhanced)" compatibility mode -->
<gdiScaling xmlns="http://microsoft.com">true</gdiScaling>
</asmv3:windowsSettings>
</asmv3:application>
</assembly>

<dpiAware>false</dpiAware>: Tells Windows that LabVIEW is pixel-based and cannot scale itself. Windows handles the layout scaling so your buttons and windows stay the correct physical size.

<gdiScaling>true</gdiScaling>: This is the magic flag for System (Enhanced). Instead of stretching the UI like a low-res bitmap, Windows dynamically rerenders fonts and standard GDI vector graphics at the monitor's native resolution.
