Smooth and CrispWe had another ultrawide LG and decided to try this one as our experience with one of the Samsung Ultrawide monitors wasn't as simple. The included software makes screen splitting a breeze for our staff. No need for technical support. When combined with the laptop monitor, our admin staff is much, much happier as they can spread the CRM page, and accounting program on the LG and then have either outlook, file explorer, or the browser on the laptop... makes life much simpler for all. The included USB-C charging port seals the deal as it keeps the personal cell phones also attached in one crisp package. The stand is also very functional as it is sturdy, allows for height and angle adjustments and projects a crisp white façade when customers and clients enter the office area.

Does the LG 34UC98-W freesync feature work with a nvidia rtx 2070 graphics card
Asked by: cromen242
Nvidia released its GeForce driver 417.71 which lets GeForce graphics cards tap into the Adaptive Sync capabilities of AMD Freesync monitors for a smooth, tearing-free gaming experience. The driver automatically enables variable refresh rates on FreeSync displays that meet Nvidia’s strict “G-Sync Compatible” requirements. The LG 34" Class 21:9 UltraWide® WQHD IPS Thunderbolt™ Curved LED Monitor (34" Diagonal), Model # 34UC98-W is not one of the 24 monitors that has earned that certification yet as of March 2015. However even though this monitor has not earned that certification, according to Nvidia, you can still manually enable Adaptive Sync support using the Nvidia Control Panel, but there are a few caveats. This monitor only supports Freesync over DisplayPort™ and Nvidia that you need to connect your GeForce GPU to a Freesync monitor using a DisplayPort cable to activate variable refresh rates. (G-Sync monitors only work over DisplayPort as well.) The other caveat is that only Adaptive Sync displays certified as “G-Sync Compatible” are guaranteed to work well with Nvidia graphics cards. If you try manually activating G-Sync on other FreeSync monitors, “It may work, it may work partly, or it may not work at all,” Nvidia says...^IFV

Connected my brand new LG 34UC98 Monitor to my laptop via an HDMI cable but the display is not showing 21:9. I accessed the on-screen menu but there is no option to maximize the display screen to 21:9.
Please advise, thanks!
Asked by: dizhanker
The issue is not with the LG 34" Class 21:9 UltraWide® WQHD IPS Thunderbolt™ Curved LED Monitor (34" Diagonal), Model # 34UC98-W. Depending on what your laptop is, you need to access the settings for your GPU to output the correct Aspect Ratio that is supported by the monitor if your GPU supports it.

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
