So, back when I was looking for ultra-wide, for a combination of work + gaming usability, I vaguely remember thinking about the 49-inch 3840x1080 monitors when they were teasing them, then went with 3840x1600, since it didn't see like those 32:9 monitors were going to be released by the time I needed them.
In hindsight, for my work needs, 3440x1440 would've probably been just fine (losing only about 11% of the horizontal resolution that the dual 1920x1080 monitors a the office gave me), and would've required less GPU grunt for gaming purposes.
But this? Yikes! That's a metric butt-ton of pixels, and seems like maybe too unwieldy of a size.
