So you're using RasPi's HDMI out to connect to your screen?
First try removing every single setting related to HDMI, screensize, etc, and start the Pi

Run 'tvservice -m DMT' should give you the modes that are possible (as far as the Pi can tell) and a preferred mode.
Compare this with the LCD's capabilities.

Dirk.

That displays native resolution is almost certainly 800x480

try to force that resolution on the Pi.
