Would it be possible to expose the ability to set DPI scaling in your Unreal solution. I believe your Unity solution has a setting, but not your Unreal one.

See forum post: https://www.noesisengine.com/forums/viewtopic.php?t=3716

I believe Unreal has 2 DPI values:

• User Setting DPI Curve - UUserInterfaceSettings GetDPIScaleBasedOnSize (See UWidgetLayoutLibrary::GetViewportScale). This is set in the project settings.
• Canvas also has a DPI scale (See Canvas->GetDPIScale()) which on windows is set from your windows display settings e.g. 125%, 150% etc.

I think the User Setting is the one you should probably use, as that's what Unreal use for their UMG widgets (Via SDPIScaler). The canvas one seems to be more for debug text, Editor etc.

In terms of implementation:

• It should probably be a setting, so people can choose to use it or not.
• Maybe it's function should be exposed and overridable? So people can override it if they wanted to manipulate it themselves at a game level
