What People Are Saying

Rated 4 out of 5 by from Great 34" I bought this for day trading to see my charts better. I used it on my 2013 iMac Pro retina (early) and my 2014 iMac 27" without issue. Also had 3rd monitors hooked up to both machines. There were a few quirks at times (it would wake up and be blank often and I had to put the mac to sleep and wake it up again to get the monitor to display, and it would also tend to change the background resolution). These issues were unique to this monitor, so not sure what's up with that - I think it it wakes in a different resoltion then changes because on my win 10 machine when I wake it up the windows are all smaller than I left them, as if the resolution changed.). Regardless the monitor is one of my favorites. Not a clean and crisp as my imac27 or thunderbolt monitor, but a really good monitor.

Rated 5 out of 5 by from Good Functioning and quality. I am happy with the functioning and picture quality of my monitor. It was easy to setup on my mac for thunderbolt.

Rated 5 out of 5 by from Amazing Monitor! I purchased this monitor a week ago because of a recommendation from AMD, after they gave me their top GPU. I most say it has exceeded my expectations on ever respect: quality, picture quality, aesthetics and form factor.

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!

Will there be a thunderbolt 3 version of this released? Or something with similar features? 

Asked by: Djrico
We currently do not have any information on if there will be a version of the LG 34" Class 21:9 UltraWide® WQHD IPS Thunderbolt™ Curved LED Monitor (34" Diagonal), Model # 34UC98-W that will feature the Thunderbolt™ 3 Technology. According to Intel, the new Thunderbolt 3 acts as a "superset" host for USB 3.1 (at full 10Gbps speed), DisplayPort 1.2, PCI Express Gen 3 and its own Thunderbolt standard and Thunderbolt 3 is set to unify ports with the latest USB Type-C standard, but we do not have any information on what ports will be included on 2017 monitors...^IFV

a notification keeps popping up saying that i need to also connect the display port, but my PC display port is tiny and the one that comes with the monitor is huge. i also cant seem to find the split option.

Asked by: AALMofleh
You need a mini display port to display port adapter, its a passive adapter and should be relatively cheap.

Hello. I would like to know if usb works thanks to the thunderbolt connection or is needed to connect the monitor to an usb in the laptop.

Asked by: MigHer
We are not clear about what you meant in your inquiry "if usb works thanks to the thunderbolt connection..." on the LG 34" Class 21:9 UltraWide® WQHD IPS Thunderbolt™ Curved LED Monitor (34" Diagonal), Model # 34UC98-W. The monitor has three USB ports (USB 3.0, USP Up 3.0 and USB 3.0 Quick Charge), 2 x HDMI ports (ver. 2.0) a Display Port and 2 x Thunderbolt™ 2.0 ports. Thunderbolt is an interconnect technology developed by Intel in cooperation with Apple that combines PCI Express and DisplayPort into a single connection, allowing for a combination of up to six peripherals, like storage devices and monitors, to be daisy-chained together. Depending on which ports you have on your computer, you can use any of the above mentioned ports to connect to the computer...^IFV

We regret the trouble you have experienced with this monitor. On the back of the unit is the input connector. There are 3 different connection types you can use. HDMI, DisplayPort, or Thunderbolt. You will need the appropriate cable for the connection type you wish to utilize.

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.
