Some time the white background not good enough to present your dashboard or report, therefore we going to search about some backgrounds make our report looking more good .
But we could face issues to find a nice background with the right size and the right colour .
My trick in this since the default page size in Power bi is the same size for the power point slides (16:9) ,usually i export a clean slide as PNG then use it in Bi as a background and it work very good for me .
