I have an older version of this LG 42.5" 4k monitor[0]. This version has 60W USB-C PD along with being an a/v input. It's good for office-type use. Not great if you want a wide color gamut or deep blacks. I find that I don't use the full height, but there's really nothing in-between this and 21:9 monitors. I also have a 34" 21:9 but find it a bit short. Next time I might go with a 32" 16:9 with VA pixels (or IPS Black from LG/Dell).
Looking at the other replies and productchart.com/monitors/large I see we now have 3840x1600 and 5120x2160 monitors now, but the VA monitors listed are too wide/short 5120x1440.
