What People Are Saying

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.

Rated 5 out of 5 by from The best display I have ever owned, easily I am a developer / programmer and I have had many setups over the years. 3 screens, vertical screens, kvm switches and this display allows me to setup my environment perfectly. Primarily I split the screen in 3 - first third is the browser, the other two thirds terminal and then the terminal I split in thirds again. No bezels get in the way of setting it up how I want. Also very nice for some casual gaming. Only wish the backing game in a darker colour. Oh and please make a high DPI 38 inch - maybe 6 or 8k?

Rated 5 out of 5 by from Stunning display Very impressed with the build quality and the image profile of this display. There isn’t much to be desired. The connection ports on the back work well as a hub for laptops and power my MacBook Pro along with display and data throuput using a single thunderbolt 3/usb-c connection. If I had one request it would be to improve the UX design of the settings menu as there are several redundant menu categories but overall it is fine.

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

The reason that the LG 38" Class 21:9 UltraWide® WQHD+ IPS Curved LED Monitor (37.5" Diagonal), Model # 38UC99-W is on our page while the 38CB99-W is not is because one is a Consumer monitor while the other is from our Commercial and Business division.

When the monitor is turned off (by power saver or manually) and then turned on again, the USB ports stop working. I have to unplug the USB-C cable and plug it again to get them working. Does anybody has the same problem? If so, will LG fix it by firmware?
