I used background wallpaper of screen and also of vertical arrangement but still getting poor quality of image. Getting zig zag lines (where green colour touch with white, below that paragraph).
Is there any other way so that I can get straight line instead of zig zag lines?
I also found a solution that every image when choose as background image of the screen, it will be of poor quality (even if we check the high quality image option.)
So it’s better to take an arrangement and then choose that image as background image of the arrangement not the screen. Arrangement show high quality images.
