Background Help

I have been setting up blackbackground lately, and I use Environments and Backdrop to swithch betweem black and normal.
This time, however, the black did noot fill the screen, as I needed it to do.
(This happened after I loaded a Daz Studio set. But even after I deleted the set, all my other saved files now do the same thing.)
I enclosed a screenshot to show what I mean.
How can I get the black to fill the entire backdrop again?
ALSO: Here is a screenshot of the set. Why does the backdrop not appear in total black, when I bring it up?

Use Window>Style>Customise Style to change the Viewport Background colour, or set your render to use the Active Viewport size preset (which of course also affects the render size). The Environment pane affects only the part of the viewport that will render.
Thanks for helping me understand that!
It worked, of course!
Really helped!!!!!!!!!!!!!!!!!!!!!!!
