38 Inch Curved UltraWide Display

38 Inch UltraWide® Curved Display

The world's first 38-inch curved IPS monitor. The 21:9 curved UltraWide QHD+ IPS Display is ideal for designers, photographers, producers and other creative professionals who need more room for big ideas.

38UC99-W QHD+ Screen Resolution

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.

38UC99-W USB Type-C™ & USB 3.0 Quick Charge

USB Type-C™ & USB 3.0 Quick Charge

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™.

Charge the battery of a connected device quickly using the USB 3.0 port. This port charges compatible devices much faster than typical USB 2.0 cables so waiting for a full charge doesn’t hold you up.

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.

38UC99-W sRGB Over 99%

sRGB Over 99%

sRGB is the standard color space of ideal color reproduction. So, with over 99% coverage of the sRGB spectrum, this LG monitor is a great solution for professional photographers, graphic designers or anyone looking for highly accurate color.

38UC99-W On-Screen Control

On-Screen Control

On-Screen Control puts a host of essential monitor settings into a handy window for quick, easy access. Volume, brightness, picture mode presets, Screen Split 2.0 and Dual Controller and more can now be adjusted with just a few clicks of the mouse, instead of hard buttons on the monitor.

What People Are Saying

Rated 5 out of 5 by from Dimensions confusing Why is it listed as 3.6" high? With Stand (WxHxD) 32.7" x 17.7" x 11.0" (down) – 15.7" (up) Without Stand (WxHxD) 35.3" x 3.6" x 15.5" Shipping Dimensions (WxHxD) 41.5" x 8.1" x 21.2" And why is it listed as wider without a stand? How is it a stand changes width? This is a fantastic monitor but it worries me that they can't get basic stuff like this correct. If they are as sloppy as this in their engineering department, I don't think the monitor will last very long.

Rated 5 out of 5 by from Beautiful Monitor, But... This is a gorgeous monitor with plenty of workspace side-to-side. Picture quality approaches the best professional monitors. But, I want the big curved screen with this readable dot pitch at the full 16:9 4k resolution. Just make it a little bit taller and 3840x2160 (or 4096x2160!) and it's absolutely my dream monitor.

I notice USB 3.0 ports only charge devices when the monitor is on. Why don't these ports provide power when monitor is off or in sleep mode? Quick charge setting is enabled.

Asked by: Mark Ch
We appreciate your interest in this monitor. When the power is disabled from the device, no power is flowing to the USB port. As such, it will not be possible to charge on the USB port when the screen is inactive.

Will LG be coming out with a Ultrawide model that has 2160 horizontal lines any time soon?  That is what this customer is waiting for.

@ gamertaboo - check out newegg - there are many video cards that support 8k resolution, so they will easily handle this monitor

Curious what you think about pairing this monitor up with an Alienware Area 51 Base desktop system that runs on NVIDIA G-Sync? Will that be a problem or should I go for it? I got the computer and am ready to buy the monitor, just waiting for some feedback

Asked by: ToddJZimmer
I'm running mine on an AREA 51 S1 (the original one) with and EVGA GeForce GTX 1080 SC2 Gaming iCX connected thru Display Port. It's running at 3840x1600 True Color (32 bit), 75Hz. No problems so far. Don't know what Gsync would buy me.

I work in professional post production and need this screen size for my work. Is there a flat version of this 38 inch in the works ? If you cannot share this info please pass the feedback requesting flat monitors of this size.

Asked by: Omen
Hi Omen. Thank you for your interest in the LG 38" Class 21:9 UltraWide® WQHD+ IPS Curved LED Monitor (37.5" Diagonal), Model # 38UC99-W.

Does this work with the new MacBook Pro touch bar with thunderbolt 3? And if so is it 4K or 5k?

Asked by: Want One Please
Yup, it works perfectly with a single USB-C from my 2016 MBP 15", the USB 3 ports on the monitor work as well. I have a keyboard plugged into one and an external hdd plugged into the other.

you've been advertising this monitor for months, when are we actually going to be able to purchase one?

Asked by: narr
CES2017 ran from January 5th - 8th and is when the LG 38" Class 21:9 UltraWide® WQHD+ IPS Curved LED Monitor (37.5" Diagonal), Model # 38UC99-W was showcased. After CES2017, it went into production soon after that. Typically, products showcased at CES begin hitting stores in the first quarter of the year, usually around Mid-March or a few weeks later. The 38UC99-W is being showcased on the LG site as "Coming Soon" meaning that it will likely come out within the first quarter of the year (i.e. sometime before the end of April). Until the units are ready to ship, we will not have any release dates or pricing for the units, but as soon as that information becomes available, LG will make a Public Announcements through Press Releases. Thank you for your understanding and patience...^IFV
