What people are saying
Rated 4 out of 5 by from Excellent width, limited height Bought this to replace an older LG monitor which finally died. Do like the curved form, as all parts of the screen equidistant. Have discovered that the lesser height (compared to my prior monitor) requires making landscape pages smaller or viewing only a portion at a time. In retrospect, might have been better to purchase a monitor with more height and less width

Rated 5 out of 5 by from Great for video editing I love the real state on this monitor while using Premier Pro, I used to have to monitors and I was a bit hesitant to make the switch, but after trying for over a month I'm not going back. I have not tested the dual computer mode but the split screen mode is not working out that great for me. The price is high but this is my work tool so I look it at as an investment.

Will this work with ChromeOS?

Asked by: waltt
The LG 38'' Class 21:9 UltraWide® WQHD+ IPS Curved LED Monitor (37.5'' Diagonal), Model # 38UC99-W is a Plug 'N' Play monitor and it has a DisplayPort (version 1.2) and 2 x HDMI ports (Version 2.0) for connectivity. It has a resolution of 3840 x 2160 so if the GPU in your unit has the right connectivity or can connect with adapters and it supports the monitor's resolution, it will work...^IFV

Why, for years, does the onscreen control keep crashing in windows 10? It randomly ALWAYS crashes and I have to either restart my PC. I'm using the latest software. I'm a tech so I've tried several things from reinstalling to cussing at the monitor.

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

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.
