[SOLVED] Dual monitors gives "Failed to create graphics device!" exception

I am trying to debug a fullscreen problem so I set up my laptop to use an extra monitor in extended desktop mode.

But now the game won’t run, it gives a NoSuitableGraphicsDeviceException.

This line gives the exception:

   // Create and initialize the graphics device.
            _graphicsDevice = new GraphicsDevice(GraphicsAdapter.DefaultAdapter, GraphicsProfile, presentationParameters);

This is with the developer version of MonoGame.
What is causing this? Other team members didn’t get this problem.

This has to do with DPI-awareness. After restarting in extended monitor mode, the game will run, but scaling is active, giving an unwanted blurring.

Is this with a Desktop Project or Windows UWP project?
