What People Are Saying

Rated 5 out of 5 by from Excellent Display for DAW After a lot of investigation I chose the 34UC98-W to display my digital audio workstation (DAW) projects. I am so happy I converted from dual 23" monitors. Whether it's showing me 32 tracks in the mixer or an entire song in the project, the need to scroll back and forth are reduced. I was concerned the PPI would be too small but it is fine for my 50 year old eyes. The curve is more gentle than I was expecting, but the curve is appreciated for viewing the extreme left and right.

Rated 5 out of 5 by from Outstanding monitor I use mainly for video editing. Easy to setup, color calibration is excellent. Functionality and features are easy to use. Response time is good. Resolution/ definition is excellent. Use with two PC's connected with LG dual controller software which which eliminates need for second monitor on the desk.

Rated 3 out of 5 by from It's good enough to use. It's good that I can have a wide screen monitor but not sure if it's good enough to use as a secondary monitor for graphic design. First of all, for some reason, I can't control the True Color Pro software to adjust colors. Secondly, the resolution doesn't seem to be closer to my Macbook Pro 15" Retina. I think price point wise, the resolution should be similar to Retina display. The last, I can't control volume with HDMI connection. I'm sure there must be somewhere but this basic function should be easy to find an use. Other than those, it's pretty good. If I considered

Rated 5 out of 5 by from Awesome monitor! Love this monitor! The curved widescreen is unbelievably immersive and the split screen feature enables the productivity of having dual monitors; combined with my laptop screen, I essentially have 3-monitors without all the bulk, cables, etc. I really like the productivity I'm getting, and the immersive experience makes it better than the dual monitors I use at the office.

Rated 5 out of 5 by from Flawless so far for me. I connect this monitor to my Surface Dock through a miniDP to DP cable and it works flawlessly at 3440x1440 @ 60 Hz. I sometimes hook up my Xbox One X via HDMI and play at 1080p. It doesn't look the best but the ultrawide curved format makes gameplay really immersive. I have LG OnScreen Control but don't use it much. I find just two windows side by side works best, and Windows 10 does that without any extra software. The speakers are good enough for regular desktop use. They're not great but I wasn't expecting an IMAX experience. The build quality is also top notch, and I like the USB 3.0 port on the back. I use it sometimes to charge my phone at my desk. The single navigation button on the bottom is also very easy to use. It takes some getting used to but eventually you get it down. Keep in mind the power brick is quite large, about the size of a sunglasses case.

How many 34UC98-W monitors may be connected via Thunderbolt to a MacPro (which has six TB ports)? I ask because I own three (3) 34UM95 monitors and they have a limitation of two (2) via Thunderbolt; my third one has to be connected via HDMI.

Asked by: DMEEPhD
Hello, you have them connected correctly as you can only have 2 connected via Thunderbolt. ^AC

For the life of me I can't figure out the dimensions as the way they are written out is confusing. What does (down) and (up) mean? Why are the dimensions with the stand smaller than without the stand? How can the height be only 3.5 inches?

Asked by: JeloRoc
Hi JeloRoc. We apologize for the error in the dimensions for the LG 34" Class 21:9 UltraWide® WQHD IPS Thunderbolt™ Curved LED Monitor (34" Diagonal), Model # 34UC98-W. The Dimensions should read as: Without Stand (W x D x H).....32.2" x 3.5" x 14.2" With Stand (W x D x H) .....32.2" x 9.1" x 17.8" (Down) and 32.2" x 9.1" x 22.1" (Up). The stand for the monitor is height adjustable and the Down and Up are referring to the height of the monitor when it is at its lower position and when it is at its higher position...^IFV

is it not possible to use pbp with two hdmi sources?? i suppose i can just buy an hdmi to displayport or hdmi to thunderbolt to address this which feels ridiculous.

Asked by: Roger Fleenor
We appreciate your interest in this monitor and its features. According to the chart listed on page 25 of the owner’s manual, the PBP mode can only use one HDMI port at a time.

So I have a classroom with a projector and six 40" displays around the room. Can this display project an image to the projector and displays while allowing me to continue working on the other side?

Asked by: Groves
I apologize, but no; according to the information listed in the owner’s manual, it appears that all ports on this monitor are INPUT jacks. Each will receive a signal, such as a PC, but will not output a signal to another device.
