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.

+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.

I got 2 of these, to replace the dual 32", 4k samsung VA monitors I was using before. I made the switch because I was getting back into gaming after a decade+ hiatus. Moved my old monitors to my work setup. Frame rates are much higher, as my old monitors were limited to 60hz, and these go up to 155hz, at a lower res (normally 144hz, you gotta enable 155hz in settings). Still messing with the settings, and seeing how I like them. The intelligence app is convenient, but doesn't always work when dealing with dual monitors. A lot of reviews claims the HDR is bad. But I do notice the HDR pop with both of mine. Likely because I only use them at night in a dimly lit room. When I first swapped them into my setup, text looked terrible, and I thought it was the low PPI. But after updating GPU drivers, text got plenty sharp enough for me. I have them installed on a desk clamp stand, and my desk is 3' deep, so I'm sitting quite far back. I increased the scaling as my eyes aren't what they once were, and had to do this with my 32" 4k monitors too.

I am so glad someone made the bullshit dpi argument for this monitor.

It. Is. FINE.

For $300 you're really going to complain about this? I came from 720p 24" monitors, a low dpi will not kill you I promise. You can still be incredibly productive. These 4k nutjobs are well, nutjobs. If you believe that this monitor will disrupt your productivity or gaming, you need to reprioritize your life.

I've owned this monitor for months and it is great for everything. PPI isn't 4k. But you also don't need 4k gpu horsepower to run it. And you don't need 240hz gpu horsepower either. The people making this argument are comparing this monitor to something several times it's price.

This is a fantastic price for a solid monitor. I recommend. If you're a loser that squirms when you see a pixel, then get a 4k laptop and you can brag about your ppi numbers to your reflection.

this one is 40", and the extra 6" quite a difference.

it's basically like going from a 27" to a 32". 40" requires quite a bit of desk space but it does boost immersion greatly. not recommended for competitive gaming though.
