When the display is changed, the layout is loaded/reloaded (if I recall correctly). You can use the name of the display to load a graphic with the same name as the display. In this example a display called  "Arcade" would load "Arcade.png", if named "Nintendo Entertainment System" then it would load "Nintendo Entertainment System.png".

Code: [Select]

local display = fe.list.name
local display_background = fe.add_image(display + ".png" , 0, 0, fe.layout.width, fe.layout.height)

function on_signal( sig )
{
    switch ( sig )
    {
        case "up":
            fe.signal( "prev_display" );
            return true;

        case "down":
            fe.signal( "next_display" );
            return true;
    }
    return false;
}
   
fe.add_signal_handler(this, "on_signal");
