The Sony Xperia XZ features a 5.2-inch Full HD display ( 1080 x 1920 pixels) of an IPS LCD kind. “Triluminous”, “X-Reality”, Sony does not shy away from throwing in a bunch of pompous marketing names to convince everyone in the superior qualities of this screen.
But first, sharpness: a 5.2” Full HD display is sharp enough so that most users won’t see pixelization. We find no issue with it, hence, no reason to complain about it not being a Quad HD display. To be perfectly exact, there is one scenario when a Quad HD display would actually be more beneficial: if you mount your phone in a VR headset, you can actually see a real difference in sharpness there. But as far as normal usage is concerned, 1080 x 1920 px is a-OK.
