+1, and curve radius is infinite. A real deal if 1.5 to 1.8m, but YMMV.

Thanks OP! Had to try one at this price level. Costco return policy more than makes up for a few poor reviews as to reliability.

Not curve. That Window sidebar will be hard to see.

My $.02...

This has a low-ish DPI of about 93 pixels per inch (PPI). This is similar to 1080p 24" and 1440p 32" monitors which are both about 92 PPI. Not horrible at all, as 1080p 24" monitors are kind of the industry standard. But nothing great. For reference, a 1080p 27" has a PPI of 82 and looks noticeably grainy for productivity work. On the other end, a 2160p (UHD) 32" display has a PPI of 138.

For productivity work, I'd argue that around 110 PPI is kind of the sweet spot. This includes both 27" @ 1440p and it's ultrawide cousin, the 34" UWQHD. Most desktop UIs look crisp, but the PPI isn't so high that you need to use any scaling.

Until you reach the point of needing to scale down the UI, increasing the PPI/resolution means increasing the amount of you can show on the screen at once. But once you do need scaling, I'd argue that you're getting diminishing returns. There's nothing wrong with getting a UHD 32" display and using scaling for a super crisp UI. But you're just paying for a better picture at that point, and not for more usable space.

One of may DPI calculators [sven.de], for reference.
