To get rid of black region on WebViewer

Hi Friends,
In my application, I use webviewer.
if I open the screen in 5.5" screen, it seems good,
but if I open is in 6,4" screen (in another device), it has black regions and these regions seems bad.

How Can I standardise it for every device ??
I tried many things but I can not do it.
