U2414H Monitor - 1m gap between top of screen and edge

Hey, just bought a new U2414H and it's great. However I've just noticed this small gap at the top of the screen which looks like it might be the result of being knocked about in transit - you can see it here: http://imgur.com/a/v8WQJ

Can anyone else with this monitor confirm whether this is just how they come, or whether it has indeed been damaged en-route? Many thanks.
