Casio LCD module

[kaninjo]

Hi!

I have problems with a 5.5" Casio LCD module. The image is too big on the screen... I tried an other module (Sharp) with the same electronic, the picture is OK.
Can somebody give me a pinout or datasheet for the MB87A144 chip from(?) Casio? I hope it has a 4:3-16:9 "mode-switch". Or have somebody any idea to decrease the vertical image size? (Only on the module possible ).
The module works with R-G-B-Sync signals.

Thanks, and Best Regards:
Kaninjo

P.s.:Sorry for my bad english.
