Which game engine are you using ? If you are using cocos2d or cocos2dx then you can use background image of 960 * 640 .Below code will scale the images according to the screen size.

CCSize frameSize = pEGLView->getFrameSize();
    CCSize designSize = CCSizeMake(480, 320);
    vector searchPaths;

    CCSize resourceSize;

    Utility :: isPad = true;
    searchPaths.push_back("hd");
    resourceSize = CCSizeMake(960, 640);

    CCEGLView::sharedOpenGLView()->setDesignResolutionSize(designSize.width , designSize.height, kResolutionExactFit);
    pDirector->setContentScaleFactor(resourceSize.width/designSize.width);
