Me = Very satisfied with this display
My general thoughts: I am very satisfied with this display. I did a lot of research on the best fit for my situation. I wanted something that appeared somewhat professional and sleek, and most of the options in the price range are tailored for gamers and look like gaming monitors. I first looked at 4k monitors so that the resolution would be that far off but there just aren’t many ultra-high res options for less than $1,300. I forget exactly how I found this display, but I am glad I did. At the time of purchase, it was $679. I noticed as of a few days later the price went up above $700. I am sorry to see that for anyone interested in it. I was a little nervous about the resolution but had to remember I was still stepping up from a $150 1080p 24” monitor. I plan to use this connection to a new MBP, I am still on the fence about waiting for the possible updates next year. For now, I am using a windows 7 machine that I built like 8 years ago. Anyway, back to the resolution, 1140p looks good compared to 1080p and the fact that the screen is enormous is a real game-changer for productivity. I use mine for school and work and man it’s amazing having the windows side by side. Where I work, I have 2 monitors set up, I just prefer this so much more though. It’s clean, using less power, fewer cables, and does the same thing. You can even get “super ultra-wide” but I think it’s a bit overkill, at least for me. I recommend reading all the specs and features because there are many. You might find more info on dell.com. Connectivity & settings: I plugged it in using a DP (display port) and it calibrated itself. I dint not change any settings, the aspect ratio was perfect! Color calibration and all settings are perfect. I will not be adjusting any of it. That’s cool to me, I mean I spent hours adjusting my 70” 4K TV. I still mess with it after years of ownership. Don’t forget this display comes with HDMI and Thunderbolt inputs with a few USB ports. So you could have this running your laptop and keeping it charged to boot. Image quality: It might be that my old monitor just sucked, but I am so happy with this purchase. The image quality and clarity are fantastic for what it claims to be. This monitor is not advertised as UHD so if you expect UHD, it’s not. But seriously, most people out the can relax about that. This is not comparable to say, an iMac retina display. So it would look out of place next to one, but as your primary display and laptop in clamshell mode, this is not going to disappoint. I downloaded a ton of high res ultra-wide images for my backgrounds. They look awesome. I ran a couple of color and gamma tests and this display was calibrated perfectly right out of the box. Plug and play, in my experience. Oh, it is worth noting that it is pretty bright, no complaints about brightness. Build quality: I like the design of the display because it looks great at the home of the office. I am not a fan of gaming-style displays, they just look a little cheesy to me with added logos and lines. I think of this monitor as a conservative luxury design like a BMW 5 series vs. a Honda Civic Type R. Nothing against the Type R, it’s an outstanding automobile and an engineering marvel. It just looks like a cartoon. The bezel is about 1 CM and it has a ¾” chin at the bottom. It comes out of the box with a film on the screen. Most people won’t even notice it, and it is hardly noticeable except for the very edge and appears to be protecting the screen so I will be leaving it on unless it starts to peel naturally or something. Included in the box: It came with several cables! I was thankful for that. I think it had a power cable, HDMI, DP and a USB-C, and some cable management accessories. The box was the least impressive part for me. It is very generic, just regular old cardboard, and the lady sat it down on its side in front of my door. Wind could have blown it over or something. Hey, she got it to me in working condition, so all good. Bonus: I also ordered a new desk pad and Logi mouse. Both are awesome!

Fine Productivity Monitor for WFH
As more content becomes 21:9, the viewing experience is greatly appreciated with a wider screen. The pixels are noticeable if you look close enough. I ran the monitor through various monitor tests and did not see any dead pixels on 10bit mode without sub-sampling. The power button indent is much appreciated. It makes it easy to turn on/off as opposed to the feeling for the small numb on the U3417 and like. I generally can fit 2 windows comfortably side by side (perhaps 38" would provide the much needed space for 3 windows). The curvature is quite high (large number / less curve) that I find myself turning from side to side instead of moving my body. The placement of the ports is somewhat low and thus prevents you from shifting the monitor to its lowest position without going too far and pinching the cables. Small incremental movements are hard to pull off and often end up as some jerking motion.

The best monitor I’ve had yet…
I have a 32” curved at work, and “had two 20” monitors at home. My eyesore is degrading in my older age, and after sending multiple emails to the wrong person, I decided I needed something bigger. This monitor works Petra’s a KVM device, the viewing area is excellent, screen contrast/brightness choices are great (mine is set in “blue blovkwr” which works well. If you are isi g two monitors, I recommend you go single curved. It saves space on the desk, but increases your working area. I’ve gotten back into 3D CAD (hobby), something impossible with two monitors. This monitor doesn’t have speakers, but uses the speaker for Your PC/laptop. This is acutely a benefit, you do t have to pick/change your source. I have two laptops connected and my keyboard and and keyboard and mouse. Switching between laptops is very simple. Actually easier to connect than my previous separate/dedicated (high dollar) KVM switch. This came with all cables needed for two laptops.

USB-C port stopped working after 2 months and there is no support or option to return it.
USB-C port stopped wiring after 2 months. Spend an hour and 6 phone calls with Dell to try to get it resolved, but they cannot find the Service Tag number as it is not bought directly from Dell and therefor they are not supporting it. The reseller says it should be supported by Dell and is not providing any help at all. Amazon is letting me hang in the middle with a defective monitor that should still be within warrantee, but no one to handle the warrantee. Update 11/06/2023. I spend another few hours with Amazon trying to get my refund. They keep on telling me I should get my refund with 3-5 business days but then when I call up to ask where my refund is they say they need to re-investigate the issue again.

Wonderful monitor with MacBook Pro
This monitor pairs beautifully with my MacBook Pros - both the new 14" M1 and my older 15" Intel Core i7s models. Color reproduction is about perfect, the USB-C connection means one cable to dock and charge my laptops. I loved this monitor so much at my office that I bought one for home for those Work-from-home days. Perhaps a little overkill, but it sure gives me plenty of space to work. Highly recommended!

Great Monitor but Such A Pain to Get Working Well
It took me three tries to figure out what was wrong with my monitor. This was the highest rated and is a surprisingly good pricepoint. The issue is, the cable is awful! I'd get horizontal or vertical (can't remember which) flashing. Thought it was a chip but turns out the cable Dell gives you must be junk. I also had the stand arrived damaged but considering this was the third try, I just dealt with it. Love the monitor but pretty furious at the number of times I had to deal with issues. FYI did a ton of research and used this Anker cable to solve my issues: https://www.amazon.com/gp/product/B072JYDQ7N/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Great image quality. Works well with Apple and PC. I like that I can plug USB accessories (mouse and keypad) in and use for both devices. The only downside is that Dell Display manager doesn’t have an iOS version. It’s much easier to use than the Apple screen positioned built into their iOS. Also bought the sound bar which I’m not as impressed with.

Beware - likely to be grey market and no warranty or support.
Monitor itself is fine as expected. However, Dell has no record of the service tag in its system, which means there's no tech support and no warranty. Dell says there's nothing they can do and to contact Amazon. Amazon refers to marketplace seller, S&D Exchange. Bottom line, Dell will do nothing to honor its warranty without providing the ORIGINAL invoice from the seller proving they bought the monitor with that specific service tag from Dell. Done with Dell. Beware.
