So I read a lot before buying this monitor but for the price and the actual product it was really nice. The only reason for 4 stars is that Dell supplies a total trash display port cable. I ordered a replacement with the monitor it self but I tested the included one. From my memory the monitor wont even wake up if it went on standby when you move the mouse. You had to manually go wake it up. So I would STRONGLY recommend including a replacement cable into your cost of this monitor. Coming from a standard 24" with a static stand, the dell stand that they include is fantastic, being able to move it up or down is great. The plastic frame around the panel feels a little flimsy but that should not matter too much unless you plan on changing between horizontal and vertical regularly. Oh and a important stat that is missing on these pages is even though it lists it as 6ms, that is not the input delay. The actual amount is between 9-10ms. Which is fine imo for a 4k ips panel.

TLDR;At the time of purchase this was a excellent pick for the money spent. Trash cable (needs replacement). 9-10ms input latency.

The monitor is great. no complaints about the display. And it has a simple, clean design, which I like.

On the other other hand, the supplied cabling leaves something to be desired. I had trouble getting consistent 4K@60Hz with the included mDP to DP cable, at least on my setup. After doing some research it turns out that one really needs a VESA-certified displayport cable to achieve a robust 4K@60hz signal. After trying such a cable, everything worked fine.

Will buy again definitely, but will not use the supplied DP cable.

Great service as usual from Wootware. This monitor is stunning, the colour is excellent and the size is perfect. I haven't had any issues gaming on this either. I've been playing BF4(avg 75fps) and CS:GO(avg 200fps ) and have been loving every minute of it.

You are going to need a fairly decent pc to run this though.
I'm using:
