Is your source clip(s), from the media pool, 4K?

You should be able to change the quick settings to match anything you want up to UHD. You can't do DCI with the free version.

Your real name is showing.

4K often has a couple meanings to the general public.

UHD = 3840 x 2160
Cinema 4K = 4096 x 2160

The Free version can do UHD. You will need Studio for C4K.

And this confusion is deliberately promoted by hardware manufacturers.
