I've experimented with backgrounds, Aegis. Unfortunately, we can't just cover the edges, due to different screen sizes for different people. There is a certain space that has to be filled with images, so that everyone sees what we want them to see. Smaller images will be split in the middle by Wikia so the edges are seen, and bigger images (wider than 2000px) remain still, meaning that parts with no details can show up on small screens.

A good size is 1920 in width, and a significant height (~1400px), because it's still adaptable to screen size, but looks like what we want in bigger screens. The height also means you don't see much of a solid color when you scroll down.
