This is the entry-level ultrawide — imagine two laptop screens side by side, but with the seam removed. You get 21:9 instead of the usual 16:9 shape, which is great for having two windows open at once without turning your head, or seeing more of a game's edges in one view.
The problem is it's only 1080 pixels tall at 29 inches wide, so the picture isn't as crisp as you'd expect from something this size. Text looks softer than on a regular 1440p screen, and you'll notice the pixel grid if you sit close. The 100Hz refresh is decent for casual gaming — smoother than 60Hz but nowhere near what competitive players want. The HDR label is basically decorative.
It has USB-C, which is handy for laptops, but doesn't deliver power — you'll still need your laptop charger plugged in separately.
