OpenGL ES1.0 libraries run differently on HVGA, QV

will OpenGL ES1.0 libraries run differently on HVGA, QVGA and WVGA

handsets? We would like to know the correlation between these libraries

and the display types?

Obviously higher display resolutions mean you can create larger window surfaces to render to. Apart from that there should be no difference.

Is it enough if we alter suface related libraries alone that is developed based on Opengl Es specification or need to alter libraries realed media, audio ,freeetype etc if we are porting the platform from HVGA to WVGA or QVGA devices ?

A change in screen resolution should not require changes in libraries which are not concerned with output to screen.
