Question / Help Aspect Ratio from 8:5 to 16:9

[Marcel Speckmann]

Hey support,
i swapped from Xsplit to OBS and i am very happy with it.
The only problem is the black border around my stream.
I know i can fix it, if i set my Aspect Ratio from 8:5 to 16:9, but i cant click in the Aspect Ratio field.
So i can't change it.

I am talking about: Settings - Video - Costum 1920 x 1200 Aspect Ratio 8:5

Your aspect ratio is determined by your resolution. Set your resolution to 1920 x 1080 if you want 16:9.

That doesnt work. Then the bottom of my screen gets cuttet

Well, if your input uses a different format you can either stream at its original aspect ratio, or you can fill the empty room with graphics/text/infos and stream at 16:9 format. The last option, which I cannot recommend, would be stretching your input, you can do this too, but it will probably not look as good.
