Warwick GB
I have to admit to having sat on the fence over 4k displays ever since they first came to market. The technology has matured and graphics cards have caught up - I use the display for both work (MS Surface PRO 3 connected via HDMI to Mini DP cable at 1920x1080 which is the only res I can get a full screen size image with so I have USB Type C to Mini DP cable on order) and for gaming (Nvidia GTX1080 graphics).

After extensive research and getting to grips with the frame synchronising technologies (AMD's Free Sync, built into this display) and Nvidia's G-Sync which requires an additional processor chip and therefore costs even more I was delighted to discover that Nvidia have developed software that is built into their Geforce drivers called Fast Sync. Net result, no need to buy a very expensive G-Sync display for gaming.

The LG display is gorgeous, in addition to the Display Port (needed for Fast Sync) there are also to HDMI 2.0 ports that will display the max resolution at 60Hz (the previous and more common even in 4k monitors is version 1.4 and that is limited to a more flicker prone 30Hz). There is also a USB type C port - upstream, so its a video input source rather than a downstream connection though I suspect that two USB 3.0 connections will get their data via this connection - still to be tested. The design of the screen chassis is elegant, smart and robust, feels and looks like a quality piece of kit. The spec sheets I read seem to suggest that the vertical movement range of the stand was limited - that's incorrect, it's got as much adjustability as one could possible need. The joystick controller for the settings control panel and input selection which also functions as the on-off switch feels a bit weird for a minute or two and then the penny drops and it's remarkably intuitive to use.

It is worth installing the proper LG software before coupling up the display as it automatically configures Windows 10 into a viewable state (350% magnification) as well as providing a desktop version of the major settings.

The screen is of superb quality and the brightness is of exceptional uniformity and even comes with it's own calibration certificate. Gaming is jaw-droppingly good, the latest Call of Duty is totally smooth and jitter free with almost photo-realistic rendering, the GTX1080 delivers a fabulous lag free experience with or without Fast Sync turned on and all settings wound up to the max.

Seriously recommended.

USB3.0 ports including cables for USB3.0 and USB-C connectivity.
Height adjustable Stand.
Built in speakers.
Excellent picture quality. 4K and 3K (1440p) superb.
Response time adjustment + other enhancements.
Power saving features if desired.
Freesync compatable.
One Display port input but two HDMI inputs - better if it was the other way round - HDMI only 30fps whereas DP1.2 connection supplied is 60FPS (Expected with HDMI though).
Slight light bleed on black display but not noticable when screen image displayed.
