I just realized there is a help section above so If a mod can move it up :)

Ive just setup a second monitor bigger then the last one I had so now its one small one big. The problem is the smaller monitor is trying to be like the big one so the backround is much larger then the other one. Ive tried google that doesnt really help so how can I fix this? and yes I tried getting another backround for the smaller one but it just clones it
