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?
