38UC99-W QHD+ Screen Resolution

The Wide Quad High Definition+* (WQHD+) resolution is four times clearer than basic HD, for stunning picture quality. Designed for display of advanced graphics on a wide screen, WQHD+ delivers an amazing 3840 x 1600 pixels.

38UC99-W FreeSync


With FreeSync™  gamers can experience seamless, fluid movement throughout hi-res, fast-paced games. FreeSync™ nearly eliminates tearing and stuttering that can occur because of differences between a graphic card’s frame rate and a monitor’s refresh rate.


1ms Motion Blur Reduction

A monitor’s response time is critical in games. 1ms Motion Blur Reduction will allow gamers to enjoy the precision and accuracy needed to play at a very high level. With a response time that is virtually 1ms, blurring and ghosting are dramatically reduced to make the in-game action smoother and gamer reactions more precise.

Display 4K video, transfer data and charge a laptop or mobile device, all at the same time using a single cable with USB Type-C™.

38UC99-W Bluetooth Audio with Rich Bass

Bluetooth Audio with Rich Bass

With a Bluetooth® connection, enjoy the music from a mobile device right through the monitor’s built-in speaker (10W x 2). The monitor’s speaker delivers powerful and vivid sound quality enhanced by LG’s Rich Bass function that covers sound under 85Hz for richer sound with impressive bass depth.

What People Are Saying

Rated 5 out of 5 by from Fabulous visual real estate Looking to have one large monitor rather than spread desktops across multiple applications, this LG 38UC99-W fits the bill nicely. Plenty of space for multiple applications, enabling seamless doc editing, coding, and multimedia editing. Colors are sharp and true, and the matte screen prevents glare. Multiple connections (HDMI, DisplayPort, etc) make hookups a breeze. I look forward to getting another soon.

Rated 5 out of 5 by from Split screen bliss! I've been using my UltraWide screen for spreadsheets and CAD these few months and I genuinely feel more productive! Comparing documents and copy/pasting info back and forth is a breeze while also be aesthetically pleasing. I spend hours in front the screen everyday and appreciate the USB connectivity in the back and the decent built-in speakers when I'm alone and can play some music or watch videos during breaks. Even the curvature seems to eliminate some glare! Great Buy!

Rated 5 out of 5 by from Best monitor I have ever used This is by far the best monitor I have ever used in my 35 years of computing. The clarity and color accuracy is amazing. I use it with a Mac Powerbook, so I have to connect a single cable between my laptop and the monitor, and everything else connects to the back of the monitor, including power and USB ports.

Rated 5 out of 5 by from Best Monitor Ever!! I had the 34" LG Wide Screen and just couldn't stand not having the 38" . . . best decision I have ever made when it comes to monitors!!

Rated 5 out of 5 by from Love the great working space My boss purchased this monitor a month ago. I was skeptical about it being any better than having 2 monitors. I was wrong. It is so much nicer having a screen this wide without the split of two monitors. And, the resolution and color are amazing. I do a lot of graphics work in InDesign, Illustrator, and Photoshop.

Is there way to switch input port from the on screen control program? The joy stick is a pain when needing to go back and forth between 2 computers often.

Asked by: Michael J 1952
Regrettably, OnScreen Control features Screen Split, Monitor Setting, My Application Preset and Game Mode Setting, doesn't have an Input Select that you can use to toggle between two external sources. The monitor supports Picture by Picture (PBP) where you can split the screen in half and designate one screen as the Main Screen and the other as the Sub screen and although you can toggle between Main and Sub screens using the Main/Sub Screen Change you still need to use the joystick to access that. The Monitor also has an Auto Input Switch which when set to On, will automatically switch the display to a new input when connected. ^AC

Does this monitor come in a G-Sync version?

Asked by: Kodiak964
Regrettably, the LG 38" Class 21:9 UltraWide® WQHD+ IPS Curved LED Monitor (37.5" Diagonal), Model # 38UC99-W does not come as a G-SYNC™ model. Currently, the LG 34" Class 21:9 UltraWide® Full HD IPS Curved LED Gaming Monitor with G-SYNC™ (34" Diagonal), Model # 34UC89G-B is the only G-SYNC™ model in our lineup and the LG 34" Class 21:9 UltraWide® QHD IPS Curved LED Gaming Monitor w/ G-SYNC™ (34" Diagonal), Model # 34GK950G-B will be the only other G-SYNC™ model to join it when it is released...^IFV

does this monitor support Thunderbolt 3.0?  There is no reference made to that anywhere on the specs.  Yet I've connected it with the enclosed cable to my 2017 MBP and it seems work.  But I'm unclear whether it's using Thunderbolt or just USB-C. thanks

Asked by: LGSFan
Hi LGSFan. The LG 38" Class 21:9 UltraWide® WQHD+ IPS Curved LED Monitor (37.5" Diagonal), Model # 38UC99-W does not have a Thunderbolt™ 3 port. To determine if the port is a Thunderbolt 3 port, look for the Thunderbolt™ 3 symbol that is used to identify such ports as being Thunderbolt™ 3 compatible. Thunderbolt™ 3 uses the USB-C connector, but not all host connections, cables, and devices with a USB-C connector support Thunderbolt™ 3. This means that a USB-C device is compatible with a Thunderbolt™ 3 host connection, but a Thunderbolt ™ 3 device is not compatible with a USB-C host connection...^IFV

Hello, I cant get this display to work properly with a macbook pro (15 inch, 2017), i.e, the resolution is poor and the colors and sharpness are awful. I've tried USBc to Display port, to hdmi... I'm getting fed up and disappointed. Will return probably.

Are you able to use a monitor arm with the 38UC99-W. I am using a standard 4.5X4.5 square mount with four screws. The weight is not an issue.

Asked by: ACG88
The VESA® Interface Satndard defines the distance in millimeters between the four mounting holes on the back of a TV or monitor (distance horizontally x distance vertically). VESA is a standard used for TV and monitor brackets and wall mounting systems, adapted by most TV brands. The 38" Class 21:9 UltraWide® WQHD+ IPS Curved LED Monitor (37.5" Diagonal), Model # 38UC99-W is a VESA® Compliant monitor that has an A x B VESA® Wall Mount Pattern of 100 x 100 (mm) and any VESA® Compliant Wall Mount or Bracket that supports that wall mount pattern is guaranteed to fit on the monitor. Please check to see if your current mount is VESA® Compliant and if it supports the monitor's wall mount pattern. The same holds true for any monitor arm...^IFV

How do I control the volume from a MacBook Pro (late 2016, with 4 Thunderbolt)? The volume keys on the keyboard don't work. The LG UltraFine do work though. The OnScreen app isn't ideal. And when I use BlueTooth, a BT icon shows up on screen all the time.

Asked by: EricSF
To control the volume of the monitor, you need to press the joystick button at the bottom of the monitor then go to Menu. Go to sound and configure the volume on it. It won’t work if you will use the volume keys on your keyboard. For further assistance, please give us a ring at 1-800-243-0000. ^AC
