Ahem...yes, I did and I reset the Display Area Setting back to its default because FIFA 15 has a bug with that setting that causes the HUD to not only move as expected but also INCREASE in size. Furthermore, I realised that on the default setting that games had their HUDs in the same place as PC and Xbox One games, in other words how the developers intended and in some games such as Diablo III expanding the Display Area Setting to the corners of my screen results in the HUD being too near the edges.
Besides, Driveclub and MLB 14: The Show are the ONLY two PS4 games out of the 60+ I have installed (disc and downloaded) that use the Display Area Setting to stretch the screen to full size on a native 1:1 pixel mapped 1080p TV such as mine. All the others, with the exception of FIFA 15 which is bugged, use it simply to reposition the HUD and are fullscreen 1080p even with the Display Area Setting left at its default position.
