How can I get Dall-E 3 to consistently create fullscreen images?

I am having the same issue. I am doing flag designs and I want them to be wide screen as well. It will sometimes make them square then add a colored border to fill the space. So annoying. I do see one thing that might improve your prompt, I know it helped mine when I realized it. I was asking for a Flag image. So sometimes instead of an image, it would make a image of an actual flag with a pole and all. When I realized what I was really wanting was just an image that I can use as a flag design and not an actual picture of a flag I removed flag from the prompt and it has been so much better. You ask asking for a painting. Many times it will interpret that as an actual painting hung on a wall, instead of an image using a painting style etc…
