What people are saying

Rated 5 out of 5 by from Best screen I've ever had When you go Ultrawide you can t return to normal size.

Rated 1 out of 5 by from Dead in under 5 months I bought this 5 months ago. It would never talk to my mac mini on either HDMI port but my mac mini still works with the AOC this was supposed to replace. My primary use case was to connect to my new macbook pro using USB-C and the picture was great so I ignored the HDMI problems. Now it's completely died.

Rated 2 out of 5 by from usb-c doesn't work Only works with original usb-c cable. If you use either a usb-c or a thunderbolt (for example if you wanted a longer cable than the super short one they provide with it), it simply will not be recognized by the monitor.... Otherwise, it has worked well. Speakers and display are fairly good.

Why do some commenters use all-caps, implying that their inability to understand is LG's problem? Also, is there a successor to this well-spec'd monitor?

Asked by: somecivilityPlease
Thank you for your inquiry. There are several monitors that can be considered as being successors to the LG 34" Class 21:9 UltraWide® WQHD IPS Curved LED Monitor with USB Type-C (34" Diagonal), MOdel # 34UC99-W since LG has diversified their lineup of curved 34" screens with a resolution of 3440 x 1440. Those monitors would be the LG 34" Class 21:9 UltraGear QHD IPS Curved LED Gaming Monitor w/ G-SYNC™ (34" Diagonal), Model # 34GK950G-B, the LG 34" Class 21:9 UltraGear QHD IPS Curved LED Gaming Monitor w/ Radeon FreeSync™ 2 (34" Diagonal), Model # 34GK050F-B, and the LG 34" Class Curved 21:9 UltraWide® QHD (3440 x 1440) Nano IPS Monitor (34" Diagonal), Model # 34WK95C-W. There are other 34" monitors in our lineup that will either have a lower resolution or add support for HDR10 but are not curved screens...^IFV

When I plug this monitor into my MacBook pro via an HDMI cable I get a resolution of 3840x1600, however when I use a USB-C cable the resolution is 3840x1440. Should it be possible to get a resolution of 3840x1600 via a USB-C cable?

Does the 34UC99-W have built-in speakers? (can't find it on the LG spec sheet; although other sites mention it)

Asked by: Nadal2018
The LG 34" Class 21:9 UltraWide® WQHD IPS Curved LED Monitor with USB Type-C (34" Diagonal), Model # 34UC99-W does not have built-in speakers. It has a headphone jack in the back that you can connect passive or active desktop speakers to and has a volume control and MaxxAudio® by Waves, which is a suite of studio-quality tools that you can use to enhance the Bass, Tremble, and Dialog (MaxxBass, MaxxTremble, MaxxDialog) settings and a Midnight Mode that lets you enjoy rich and full sound at a low volume...^IFV
