corona simulator doesn't show full image

I'm creating simple game using corona.

First thing i'm trying to do is load the background image; but what i got is that, corona simulator show small part of image at the top most left side and the rest of image stay black even if i used all the scaling mode and i'm sure from image size.

Then i added three parameter to the display.newimage method so i got better situation but i still have a black bar on the left.

My config.lua 

application = {
content = {
    fps = 60,
    width = 320,
    height = 480,
    scale = "zoomEven",
   -- xAlign = "center",
    --yAlign = "center",
    imageSuffix = {
        ["@2x"] = 2;
    },
},
}

and main.lua

local background = display.newImage("images/clouds.png");

first result on all devices enter image description here

then what i made to got better result is make this small edit to main.lua

local background = display.newImage("images/clouds.png",230,150, true);

and the second result enter image description here

display.newImage() by default will want to draw the object at an X, Y of 0,0. This represents the center of the object. You can either change the anchor points as listed above. You can provide an X, Y as parameters to display.newImage() or you can do:

local background = display.newImage("images/clouds.png");
background.x = display.contentCenterX
background.y = display.contentCenterY

I personally prefer this method because you explicitly position the item.

You must modify the anchor property, this property allows you to control the alignment of the object along the x or y direction. By default, new objects have their anchor set to 0.5 corresponds to a center alignment. By setting it to 0 is meaning the left edge of the object.

local background = display.newImage("images/clouds.png");
background.anchorX = 0
background.anchorY = 0
