DellUltraSharp U4025QW 40" Class 5K2K WUHD Curved Screen LED Monitor - 21:9

Upgraded from a Dell 3818dw widescreen. All the reviews online I've read (or watched on YouTube) about this monitor are spot on. The color is excellent (as been my experience with most Dell Ultrasharp monitors), 120Hz is a nice upgrade, as is HDR (abet only HDR600, and not HDR1000) which is bright. Black level is really good for an IPS panel - this display uses "special new-tech" called IPS-Black. Not as good as OLED, but better than the last IPS panel. Viewing angle is very wide. Response time is adequate for professional use - this is not a gaming monitor, rather a monitor designed to get work done - be it coding, photo/video editing, or 3D modeling, although it works for the light gaming. The built in KVM works well, with the Thunderbolt connecting to a Macbook Pro, while the HDMI connects to a KVM that has 4 systems on it. It is nice that you can turn off the 2.5GB network from switching with the monitor's KVM so the one device you want to use the wired connection (like the Macbook Pro on Thunderbolt) doesn't loose it's wired connection when switching to the other device - little details like that show that the folks who designed the monitor actually deal with these use cases. Highly recommend, especially if on sale.

Really lovely, if pricey, monitor. VERY easy to unbox and get on desk, pretty easy to set up all the cords, but I'm not really using all the features. My work laptop will not cooperate with the switching software due to security features, but my personal laptop could. So instead I switch one cord and that works. Nice and neat on my desk. Beautiful color and clarity. I do a lot of photo post-processing (Adobe LightRoom and Photoshop) and it's great for that. Also terrific for multiple work windows. Great to have a seamless workspace vs the 3 monitors I was using before. I'm very happy.

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.

First, I want to say I have no regrets. I wanted to give it 4.5 stars but it only allowed whole stars. I use it for 95% productivity.The most important thing to remember is routing your cable matters! I hooked up two computers with almost all ports used. I noticed a significant lag with my laptop, connected via USB-c. I researched the issue and someone on reddit mentioned that they fixed a similar problem by separating their hdmi cable. I undid the usbc cable and separated it from the bunch. Mind you, this is the provided cable. Speed jumped back up to normal. I confirmed it by routing it back with the bunch, going through the opening in the stand. Back to crawling speed. I couldn't believe it.Brightness had to be turned way up, but now it's perfect. Beautiful text and image clarity. The software is easy to get used to. Kvm works great.My only issue is the horrible speakers. For this price, I expect decent speakers. They were below par imo. Too muffled.In the end, don't wait. Just buy it. I researched for months and waited for the price to drop. Reality is, you have to take into account the great resale value. In a few years when there's a new iteration, you can still sell this one for a good chunk of what you paid.
