for testing purpose I need to be the more accurate with how the real website will be displayed.
When my tests have a bigger screen ratio than what was designed => My testers have the prototype centered in the middle of the screen.
Changing the mode is not a solution because it change the zoom which is not satisfactory in term of testing protocol. (We design in scale 1 we want to test in scale 1)
When the screen height is not the same it create even some difference in rendering
