Trying to get a good background and man this thing is finicky.  The manual says the display is 2400x480.   So, I have tried the following:

A 2400X480 pixel image in high, middle and low qualities (hoping the unit would squeeze it into view)

A 8##X480 (16:9....I can't recall the width) pixel image in high, middle and low qualities

Same images as above but @ 479 pixel height to see if 480 is a threshold.

Changed the tag from .jpg to .jpeg

A much smaller image.

All alpha character file names

Earlier I had found a bunch of images on the web I wanted to try.  Some worked, some didn't.  

Here's the kicker about the ones that worked......if I modify them in any way, the unit no longer sees the file.  Even more - if I just resave the image that already works in PS without making any changes whatsoever the unit stops seeing it lol.  I tried resaving it at higher quality than the original, then lower quality and either way the unit stops seeing it

So what's the formula?

There's an option called "trim" .. its auto fits the picture to fully fit the screen.

Did you manage to figure it out? I just got my X8500 and loaded two pics on the sd card and it does not even see them. I managed to get my movies to work but not pictures Im tring to put these images on as my back ground.
