hi and thank you for reply this is the screenshot of my settings :
ok, first of all i suggest you to use always true 16:9 resolutions, you are using 960x640, this isn't correct 16:9 resolution, better if you use 960x540 or another from these

most of today's devices work on 16:9 resolutions, with some tablets exception that still work on 4:3 or similar, but are a minority.
please post also a screen of you layout when i can see layout size too, and how you manage window content
