How to change transparent artboard to white?

When I create a new document based on the HDV/HDTV template, the artboard is transparent. This makes it difficult for me to work on. How can I make the artboard white?

One way is to use document setup to change the transparency display color boxes both to white, so that even though a checkered grid is displayed as the background, the checkered pattern is white alternating with white = solid white.

This seems kind of silly and feels wrong. When I look at new document created with paper templates, which have white artboard, they don't use this method because the checker pattern in document setup is not both set to white.

I read on the web a way to do this is to change the first color box in document setup to white, then check the simulate color paper box. Nothing happens. It's still displaying the checkered pattern.

Any idea how to do that? Ultimately I want to create a template with a white artboard to replace the default HDV/HDTV template. When I import the file into premiere I still do want the artboard to be transparent, so drawing a white box is also not a solution.
