LG has continued to push the limits of 21:9 aspect ratio monitors over the years and its latest three additions are something to behold. Ready to debut at IFA and coming to the US this fall, they include the "world's largest" 38-inch curved 38UC99 model that goes on sale in September for $1,500, a 34-inch curved 34UC79G due in October for $700, and the flat 34-inch 34UM79M coming in November for $600.
That massive 38-incher packs a Quad HD+ resolution of 3,840 x 1,600 and is apparently the first ultrawide monitor with a USB-C port built-in. The 34UM79M has integrated Google Cast support (plus built-in support for multitasking, so you can Netflix while you work without giving up any screen space). Finally, that curved 34-inch model is pitched as "the world's first 144Hz IPS 21:9 Curved UltraWide gaming monitor," with AMD FreeSync included to cut down on stuttering and tearing when the action gets hectic.
