It worked great before. I intentionally created extra large banners.

1) On my browsers I shrink the text to 80% or usually 90% to see more on my screen. This leaves a graphic gap that looks terrible.

2) Instead of making day mode and night mode banners I made banners with a light and dark end, often with the main shared interest in the middle. Then I'd position each accordingly in the code.

If large banners are the problem I can correct. If positioning is a problem I can correct. I just don't understand what the issue(s) is/are.
