Please, don't mess the "screen DPI" and "scaling factor"!  Bigger DPI
means that more pixels may be used for drawing some screen element or
character and, therefore, have more clever on-screen image in
comparison to the screens with lower DPI.

I don't try to say that you mess them indeed.  But I'm afraid of it...
