Ok i re-read your post Mr Womble and yes you are confusing canvas size and image size.
I'm not - what i'm reading - if i am correct is that you have the central screen of 3/5/7 whichever launcher you are using as the screen size - 480 x 854
Now if i have an image, say Android Logo at 480 x 854 and increase the CANVAS to 960x854 then although i am left with the android logo still on my centre screen i get nothing on the spill-over so when i scroll left and right all i have is blank areas
Now if i use my way of having a complete image of 960x854 so that it fills the full background, you get a complete experience when scrolling through - check out post #84 on the below link to see what i mean

to clarify what i mean i have attached a printscreen of photoshop

3rd image 960x854 with full screen image
