10/10 would monitor again. This monitor took a punch to the face and is FINE. P.S. If you are in VR and Zed hord you don't punch them... the monitor is still in front of you

This is the second LG monitor I purchased in the last month, as the first one didn't have the display port plug I decided on the 34UM88. Great decision to upgrade.

When it comes to ultra-wide monitors you will either really love the expanded viewing area or you’ll just hate that it takes up too much space. If you’re a Photoshop user or just do office work the added space will give you enough room to have two windows side by side without having to have a dual...

    Great picture quality, 2k resolution, very good contrast, IPS panel, Lots of ports, 99% sRGB color gamut

Don't waste time on this monitor. I, like hundreds of others, received a monitor with the mounting screws loose inside the back case and now must hassle through a return for no reason other than unbelievably poor quality control.

Worst costumer service I ever experienced by LG, would avoid the brand at all costs

I purchased the monitor a couple months back and the monitor is great but slow on the start-up.

The monitor comes with a 1.8m Display Port cable, a 1.8m HDMI cable, stand, psu and mains cable, an instruction leaflet and a CD containing some utilities and drivers. From what I can see you don't need to install the drivers in to Windows 10.

Love this screen. Don't use the onscreen split controller as much as I'd thought I would because it dictates window-size too much, but its there if required.

I've owned this panel for a year (almost to the day) - there are newer ones out there with nicer features (a thunderbolt 3 port, for instance), however this has served me well, and I've had no issues with it at all.
