Great Premium product but overpriced...
Another Great Premium Monitor from Dell with excellent for 2025 Specs!
BUT with few Cons:
- contrast are not so good in real life (spec 1:2000) due the luck of IPS matrix. great for work in slightly dimmed working environment w/t sun.
- plastic feels cheap for that price, but normal for corporate expenses.
- prepare extra space on table
- mostly for professional usage
- NO Remote control :(
Pros:
- Native 5K Resolution at 120Hz w/t DSC
- perfect curvature of screen (less is better)
- Tons of Connectivity features for IT Pro users
- Great for eye health and long session
- Extra 33% of working space after 16:9, 32in monitor
- Bunch of usb Ports (B/C ) including power delivery
Would be nice to see "Light version" of U4025QW with the same Panel and spec but w/t expensive "Pro HUB" features. The DP + HDMI + 1UpStream(USB-B/C)+DownStream(powered 1USB-C + 1USB3.0) ports should be fine for most demands. Probably called: Home/Personal or Productivity Edition with new code "U4025QE-H/P".
Double check with production pipe and accounting dep for targeting market.
Thank you DEll...
Firm 4+ stars.

All I can say is "wow"
A picture can hardly show the amazing quality of this display, but I've attached one to give you a general idea. I should say that I am not a gamer, so I can't comment on that aspect of this monitor. But for productivity - such as being able to see an entire spreadsheet without horizontal scrolling - it is a game changer. At 120Hz with resolutions up to 5120 x 2160 the quality of video and graphics is stunning.
The built in hub has more ports of every kind than I will ever use, and the KVM switching has eased switching between my Mac Studio and Debian Linux server as simple as pressing a button on the back of a monitor. I know this is a lot of money for a monitor, but assuming it is long lasting, this will be the last one I buy for years to come. I spend 8 - 10 hours a day at my computer and this has made that time so much more enjoyable and productive.
I should mention it was plug-and-play for both my Mac and Linux operating systems. I plugged it in and it worked.

The best…
5120x2160! Did you read the 2160 vertical!? Yea I can’t stress that enough. Gosh I find it so frustrating there arnt more options in this space.
Here is the deal, if you have multiple monitor setup (and you should if you have a work station) you likely will have a couple of 4k monitors kicking around. Now these 4k monitors are staples, and they all have 2160 vertical. If you have 1140 vertical like almost ALL ultra wide monitors do then there will be this annoying stepping with your mouse when you go from one screen to the next. It drives me nuts that the standard for these ultra wides does this. If you don’t have the same resolution vertical from one screen to the next then you won’t have a seamless transition from one screen to the next. It’s just the facts.
This dell is one of the only curved ultra wide monitors with 2160 vertical resolution. It runs at 120 hertz which also believe it or not makes it one of the only 5120x2160 resolution monitors on the market to do that. I’m sure you can tell by my writing I have owned a lot of high quality monitors in my time and this one for me is by far the best.
I’m switching from a none curved ultra wide 32” LG that runs at 60hrtz. Needless to say this is way better, and sadly there was like this burn in that occurred on my LG that would eventually go away but stick around for the better part of a day. This ultimately put me back in the market looking for a replacement.
Point being, now I only buy dell monitors. I’ve never had issues with them , they have great color reproduction, pretty affordable (as of now), basically super reliable all around.
Obviously I’m not thrilled about the lack of options for folks that have real work to do on there pcs. All this gamer b.s. in the marketplace, it’s all junk as far as I’m concerned. So if you actually have productive things to do on your pc then you can’t do much better then this monitor, I highly recommend. My only gripe is I wanted a smaller version of this maybe a 32” or 36”, it simply doesn’t exist on the market as of now. However, this works for me, the curved surface buys me back a little desk relestate, and it’s something I really missed with my previous monitor.
Side note, I definitely recommend monitor arms for all your monitors. I bought one for the larger center monitor (this one) and it works great. Just be sure you buy one that has a high weight capacity, ideally 44lbs or more. This monitor given its size is 42lbs I believe (although honestly it doesn’t feel nearly that heavy). So just be prepared for that. Hope this is helpful, and I hope the manufacturers wake up one day and realize this screen resolution isn’t a nice to have, it’s a must for a lot of people.

Perfect “Command Center” Monitor for Mac Studio – Worth the Money
Title: Perfect “Command Center” Monitor for Mac Studio – Worth the Money
I’m using this Dell U4025QW with a Mac Studio M2 Max, and it’s exactly what I wanted: a huge, sharp, curved workspace that also handles games really well. The 40” 5K2K screen lets me keep Docs, email, browser, and gradebook all open at once without feeling cramped, and the curve makes it comfortable to use for long stretches. Text is clear, colors look great out of the box, and bumping it up to 120 Hz makes macOS feel noticeably smoother.
The Thunderbolt/USB-C hub is a big bonus – one cable to the Mac, and everything else (keyboard, mouse, etc.) can live on the back of the monitor, so the desk stays clean. It’s not cheap, but if you live in documents all day and also want your games to look and run smoothly, this is a fantastic “do it all” monitor and I have zero regrets about the purchase.

The best business monitor
I have used many of the monitors in the Dell UltraSharp line and thought that my previous monitor, the U4021QW was the apex of Business monitors. The U4025QW improves on it in small but meaningful ways. Looking at the monitor, you can't visually tell the difference at first glance.
To me the ultra-wide curved monitor format is preferrable to dual monitors. The 5120 x 2160 / 21:9 screen ratio gives the business user more vertical space while not sacrificing the horizontal space. Many ultrawide monitors give you the width of 5120 but stick you with 1440 vertically. That resolution always felt cramped to me.
This connectivity on this monitor far exceeds its predecessor. It is upgraded from Thunderbolt 3 to Thunderbolt 4, adds 2 usb-c ports and one USB-A, giving a total of 5 USB-A and 5 USB-C. This allowed me to replace my old desktop dock and go with a direct connection to the monitor for everything.
When reading about the monitor, I thought the drop-down ports were a bit gimmicky, but it is a big improvement over the location on the previous model. This is very accessible and helps with wireless devices whose signal degrades by being placed behind the monitor.
The monitor is pricey, but I think it is worth it if you are on your computer all day every day. As on co-worker once said, the monitor is the part of the computer that we use 100% of the time we interact with it.
