Impressive monitor. Perfect for home office (not gaming)
I work for Cisco and they installed these monitors were I work as we moved to a hybrid work environment. Once in the office I had to have this for my home setup replacing my existing two 24" monitors setup. Incredible picture quality and plenty of room to multi task. Not for gaming as the refresh rate is only 60 mhz. The USB hub I thought would not really be necessary but now that I have it setup it is perfect. Only a few cords on my entire desk!

great WFH monitor!
I absolutely love this monitor for my work from home gig. We use a lot of different programs and its nice to have a lot of screen real estate to have multiple windows open and be able to reference anything at a given moment.

I'll never go back to a "Noramal" sized monitor
Once you edit a movie on this bad boy, you'll never be able to go back. Imagine having the whole timeline at the bottom of the screen. Saves so much time scrolling.

Everything's amazing except the resolution--and restocking fee
The "hub" aspect of this monitor is fantastic. Everything plugs into the monitor itselfโall your USB gear (mouse, keyboard, backup drive, microphone, whatever you've got)โeven ethernet! And then ONE cable connects to your laptop, and even charges it. The screen is immersive and curved just the right amount, and the color fidelity is sensational. The problem, though, is the resolutionโthe number of pixels per inch (ppi): only 110 ppi. For comparison, the MacBook Pro's screen is double that in each direction: 218 ppi. If you're used to a Mac, the Dell's image is upsettingly blurry. You'll be in great shape for photo and video editing. But for reading, editing text, or using apps like Indesign and Illustrator, you'll really mourn that low resolution. I wound up returning this monitor. (BEWARE! They changed me a $235 "restocking fee" after I returned it!! There is NOTHING about this on the item page.) I bought the LG 34WK95U-W UltraFine 34-inch screen instead (it's ultrawide but NOT curved). It's got 163 ppi, which looks razor sharp, and I'm in heaven. (It's also much more expensive; now you know that there's a direct correspondence between resolution/size and price!) The LG isn't a connection hub like the Dell; it has only two standard USB jacks on the back. But by adding a little $12 USB dock to the back of the LG, I still get the convenience of having only ONE cable connect to the laptop!

Excellent seller, fraudulent and deceptive manufacturer with poor tech support
The seller is amazing but DELL customer service and tech support is horrible. A sales representative stated in no mincing of words that I would have a seamless experiencing using this display with my 2020 MacBook Pro M1. The volume control does not work. Evidently this is a DELL facing driver problem that is a known issue and yet DELL still said that their product is plug and play with my MBP. In fact I called them recently again and acted like a consumer and the sales rep stated the same thing, this is display is a plug and play seamless experience with Macs. When I called them out they tried to backpedal. The forums say they are working on a solution but the last response from DELL was from February 2021.

Mac users, don't write this one off so quickly!
I was initially worried based off others reviews of using this with mac, but it works perfectly with my macbook pro, albeit with some tweaking. Here's a tip, it's not going to look good out of the box with macos, for some reason apple can't figure out external displays (or more likely they prefer you use theirs instead) but if you get an app called better display from the app store, you can fix the resolution issues easily. With that fixed this monitor looks great and is a huge improvement in terms of size and color from my previous 27".

Mostly great
Had it for 9 months--works great! I wished it was a bit more curved, but it's good. The base is good quality, but I recommend a monitor arm for proper eye height. The screw holes for the universal mount are recessed, which is not good, so I recommend using 5/8" rubber washers (2 per screw hole = 8 total) to make it flush. Might take another thin metal washer to get it perfectly flush. https://www.amazon.com/Danco-88574-Rubber-Washer-10-Pack/dp/B001AZM75K/ref=pd_ci_mcx_mh_mcx_views_0?pd_rd_w=2bzFc&content-id=amzn1.sym.225b4624-972d-4629-9040-f1bf9923dd95%3Aamzn1.symc.40e6a10e-cbc4-4fa5-81e3-4435ff64d03b&pf_rd_p=225b4624-972d-4629-9040-f1bf9923dd95&pf_rd_r=0DPJYB7J14EHWG7E8STP&pd_rd_wg=jr1nJ&pd_rd_r=25a1df1d-5c76-4e8c-8b43-26fc75aaa8bd&pd_rd_i=B001AZM75K&th=1 or pick up variety pack from Home Depot. Also need 4 extended screws M4-0.7 x 20mm (amazon or Home Depot).
