Hi
The Odroid U3 can’t handle the 800x480 resolution.
U3 can support only 720x480, 1280x1024, 1024x768, 1280x720, 1920x1080 resolutions.
how you have to integrate the Manga-screen withe U3 ?
yep and currently we have this resolution problem 
I have sent an odroid U3 to the manga’s screen, it seems to me that he had succeeded to obtain the full-screen.
