How to make application run at a different scale than the one in windows display settings?

Unity Engine

I’m currently developing an application for Sony’s Spatial VR monitorusing the plugin released by Sony. The screen is a 4k monitor so it’s scale in windows settings is recommended at 300% so that everything is readable.
When I compile the application and run it the application screen is also scaled 300% so the we can only see a small percentage of what we should be seeing. The application runs well when I set the screen scale to 100% in windows settings.

Is there any way that I can specify in unity that the application is supposed to run at 100% scale regardless of what is set in the windows settings?

The monitor is the one seen in the following link.

Any idea on how I can get around this?

This is what I do to match the resolution…it works for me…and it works for 2k and 4k resolutions that I tested.

FullScreenMode fullScreenMode = FullScreenMode.Windowed;
Screen.fullScreenMode = fullScreenMode;

Resolution currentResolution = Screen.currentResolution;
Screen.SetResolution(currentResolution.width, currentResolution.height, fullScreenMode, 60);
