What People Are Saying

Rated 5 out of 5 by from Just Brilliant I've had this for two days now and the 'out of the box' experience was simply stunning. The colours are great and using a Macbook Pro Retina and Mac Mini required no extra software or drivers. I've had a previous LG widescreen (flat screen) and I just couldn't live with the back light bleed. This is in a different league in many ways; I have no discernible backlight bleed, it's absolutely beautiful to look at (and not just the screen - everything about this monitor screams quality) and the price! It's more expensive than my last but worth every single penny. One thing that surprised me though so hopefully this will be a tip for others. There are two HDMI ports and two Thunderbolt ports - the HDMI are selectable meaning you can pick which one you want to display. Thunderbolt only has a single selection meaning the first device active gets the monitor and the other port effectively becomes the daisy chain port for other devices (but not another computer). Given I wanted to put a Mac Mini and MBP on the same monitor using Thunderbolt is a little disappointing - however, there are other options such as HDMI or Displayport which will achieve the same ends. Bottom line: It's so good I want another!

Rated 5 out of 5 by from Love these two monitors. I bought two of these monitors to do genealogy with. They are absolutely perfect as I have them side by side for a 65 inch arc of display length and can put up an enormous amount of data and research material. Great monitors.

Rated 5 out of 5 by from Outstanding screen, almost flawless I got it 2 weeks ago and I love it. LG really learned from issues of previous ultrawides and this one is nearly perfect. Almost no backlight bleed, beautiful picture, slim and light build, aggressive curve. Best ultrawide on the market and I had few before so I know what I am talking about.

Rated 5 out of 5 by from First Ultra Wide Curved Display I was completely shocked at how the experience with an UltraWide Curved Monitor was so positive. I currently have it connected to my MacBook Air (Thunderbolt), PS4(HDMI), Xbox One(HDMI), and Alienware Area 51(DisplayPort). I could not think of a better setup. The only CON I notice so far is that there is so light bleeding in the lower left corner. It's noticeable when Black but when color shows, I can barely notice it. Love it!

I run Windows7 on a MacBook Pro and will connect the monitor via Thunderbolt port. Is a Windows reboot required to get Windows to recognize the monitor?  Or should it automatically recognize the monitor when connected to a running Windows boot?

Asked by: ppdd
We appreciate your interest in this monitor. According to our information, it appears that the Thunderbolt technology works as a Plug and Play connection. As such, if the cable and the port in use are all correct, the setup should not require a reboot of the system.

Can you hack the refresh rate to get it to 100?

Asked by: castl3bravo
I apologize, but no; this monitor is not designed for compatibility with resolutions at 100Hz refresh rates. The highest compatible refresh rate listed is 60.317Hz, but the recommended refresh rate is 60Hz while viewing the full 3440x1440 resolution, as listed on page 32 in the product specifications.

LG has the most beautiful 34" curved monitors on this planet. Why don't you put G-Sync modules into one of them? All these other "gaming" oriented monitors are not adequate for a living room.

Asked by: mid aged gamer
We are right now trying to find a way to do that for everyone.

Does LG have any utlra-wide monitors that have two DVI input jacks? I have an HP latptop and HP dockingstation that has two DVI outputs. I've been using two separate monitors. I'd rather one physical monitor with split screen.

Asked by: mojojammer
We have 51 monitors in our line up of varying sizes and features. Some have 2 x DVI-D inputs and some have Thunderbolt input/output ports that allow you to connect up to six compatible devices, moving data between them with incredible speed. Most come with the software to run the 4-Screen Split feature which divides the screen into as many as four customizable segments, two-by-two so you can see four different windows at the same time. There is also a Dual Linkup feature that allows two compatible portable devices--such as a computer, camera, phone, or Blu-ray player--to be connected to the monitor, and both can be viewed on the same screen simultaneously. Note: To use Dual Linkup, one device must be connected to the DisplayPort while the other is connected to either the HDMI or DVI port.
