Dell - UltraSharp 40 Curved WUHD Monitor - U4021QW

39" (well 40") since I got used to starting with my previous Dell U4021QW, then U4025QW.

Have been using the Dell U4021QW for a couple of years with an M1. Always switched between 5k (too small) and 2560x1080 (too big) until I found BetterDisplay. With 120% scaling, it is perfect. My XBox uses 4K at 60FPS. I think the newer U4025QW supports 120Hz I recently tried out the Samsung S9 Viewfinity with the same resolution as the Mac Studio Display, but noped out immediately. What was I even thinking.

Hey, I'll chip in since I'm in the same boat, I can also grab U4021QW for $600 in perfect condition and warranty and I've been eyeing U4021QW - these can be had for around $900 if you get lucky. U4021QM is 60Hz, both HDMI outputs can only do 30Hz so you need to use USB-C and/or DP. U4025Q is 120Hz and there was a recent firmware update that addresses some MAC issues. I'm personally rocking AW3821DW and U3818DW. I do enjoy playing games here and there but I see no difference 60Hz vs 144Hz when it comes to productivity. I may grab U4021Qw just to check out since the price is so good. It's up to you how much you want to spend. HTH.

I have a Dell u4021qw. It is a 5K2K monitor or roughly 2 - 27" 4K monitors beside each other without a bezel. The pixel size is 5120 x 2160. It is not retina but I am a coder so it doesn't really bother me. Currently it is hooked up to my M1 Ultra studio but I had it hooked up to my M1 Mini before that. It has worked without a problem.

I bought a Dell U4025QW shortly after it came out for gaming and WFH. It made me hate my 3440x1440 monitor at work enough that I bought a used U4021QW (same resolution, worse contrast, and 60hz) for the days I’m in office since my work wouldn’t buy one for me. 2160p Ultrawide is insane for productivity. The U4025QW is solid for gaming as far as IPS panels go, so long as you’re not competitively playing twitch shooters or are especially sensitive to smearing. If either of those apply, a second OLED monitor for gaming is probably the way to go, or one of the new OLED 5k2k monitors coming out if your productivity needs are pretty modest compared to gaming. Running a 4080S, some modern AAA games are choppy at full resolution and quality. Turning on features like frame gen and DLSS or bumping quality down a bit has always gotten me acceptable performance, lowering resolution down to 1440p can also work well for games that aren’t particularly text heavy

I have my 800r for gaming on the same desk as my 2500r. Have never wanted to bend either. If anything, I'd want a bigger curve on the 2500r Dell 😅

Ive used both, have also had the LG 45 5K2K and Samsung 57. Currently have the Samsung 40 5k2k. The LG text issue makes it pretty awful for productivity. The vertical space is essential, so Id recommend the Samsung 40, plus I believe it's on sale

I just got the Dell 5k2k 40inch but this one has OLED and got me all interested in it. It’s also slightly bigger too. And that button switch for a higher refresh rate is a welcome function.

I'm going back from a single ultrawide to a dual monitor setup. By adding another ultrawide. My 40" Dell will move to the top and at the bottom I'll add an LG Ultrasharp 45".

Bad timing, Samsung Australia just finished an EOFY sale including monitors. I have and like the lg 38wnc monitor. Great for productivity with some extra vertical height (1600px) and good for gaming with up to 144hz. Not oled good but still good. I was very tempted by the lg oled 45 with 5k2k res, but it’s expensive and not sure how it would be for productivity. If I didn’t care about gaming the dell 5k2k 40 inch looks great but it has slow response times, so not useful for gaming.

Sounds like you want to buy a bunch of expensive stuff hoping to do something with it. That’s backwards, figure out what you like to do first, then buy the stuff to help you do it. To answer your question, from my experience, 3 monitors is too many for one PC, two is ok if you need lots of stuff at a time on one PC, an ultrawide is the best. Having said that, I work on Blender and play games, and for fps games I use an ultrawide 1440p, but for Blender I much prefer my 27” 4K monitor, it’s much sharper and just the right size. The only upgrade I would consider for Blender is the Dell 40” 5K ultrawide, but it’s extremely expensive.

I work during the day and game during the night on a LG 45" 5k2k. Whilst its good for productivity, the curve is honestly annoying for it and if I wasn't gaming, would drop to the Dell 40" 5k2k IPS.

I bit the bullet and went with the 40” ultra sharp. Should hopefully have it in a week or so

There were sales going on last week for 1599 at Adorama and B&H so Dell priced matched to that price. There was a 10% Rakuten cash back and 5% chase cash back as well for 100$ max. Total will hopefully be 1456 with tax Downside is Dell takes 10 years to ship

45” makes sense so you don’t have to scale text. 40” is borderline where 120% scaling makes text much easier to read. At least that’s how I felt with the dell 40” 5K2K.

I've got the Dell 5K2k 40" at work and it's amazing, but I love my 34" 2K 240hz OLED at home for gaming because the 5090 gpu needed to push games at 5K2K is way out of my budget. 5K2K ultra wide is better for productivity and less demanding games imo.

Of all the monitors I've had the chance to look at in person, I liked Dell's 5k2k the most, but I think I'd prefer something even a little bigger

Get one of these 5K2K displays and thank me later. Won't need to deal with Better Display to lower resolution even further LG has two, one 34" and another 40". Dell has two generations of them as well.

I have a 49" Dell and if I'm honest, I spend 99.9% of my time using the 27" LG Dual Up monitor that's off to the side of it. The 49" is too squat, short. I just bought a 40" curved Dell and the Samsung 57" (that's basically two 49's stacked on top of each other without the bezel.) I'll try them both on the desk for a few days then send the one I don't like back. I'm learning towards the 57 because I love the width, it was just the height of the 49 that I couldn't live with.

I’ve got the Dell 40” 5k2k, I replace two 27” 2560x1440 monitors and love it. Best decision I made.

Yes , i recommend the DELL 40" ( 5k x 2k ) IPS !

For work I would suggest Dell 40", not as much realestate but 120hz, 1800r vs 800r with lg and 140w passthrough if you use laptop. Also its IPS black which is a nice bonus. I'm not sure where you live if there are decent miniled alternatives but this is something I would look into. Also if you find good alternatives please reply as I'm also in the market for a work oriented ultrawide :)

So the dell model i mentioned is Dell Ultrasharp 40, 5k2k resolution (so even better ppi than LG), great color accuracy and with some tweaking you can run games at 120hz (not sure what issues people had, but some default settings I think). It will not have deepest blacks or the best response time, oleds are much better at that but if you're a casual gamer and need something for work primarily then this is really good. Expensive but good :)

Get the Dell 40 in

Own both the 5k ones. Imo the dell is worth the extra money for the better pannel. Refresh rate and brightness are very noticeable. I was next to a window, but the shit brightness drove me crazy. Kvm is much better. Ips black also, basically a big upgrade in every way. And much better if you do the odd game. The lg isn't even a proper 72 hz, most reviews recommend to just run a 60. Although I ran it 72 and didn't notice the issues they were on about it. As far as the sweet spot for aspect ratio, it's the best I've used. Also of note, my lg did develop a stuck pixel after a couple of years, the dell has been fine so far. Also, while the lg has got quite a few ports, there were some limitations to the whole kvm style functionality that wound me up. I can't remember now what it was, but I would look at the manual to see that you can use it the way you want. Basically I upgraded to the dell cause the lg was just a bit dissapointing . Also, ignore the 1337 gamerz, 1600p is a shit resolution, and you don't want a super pronounced curve for working. Even for gaming, the projection used in games isn't designed for a curve, so it's really a bit of a weird distortion, even there.

I had my mind set on 49” or 57” Samsung until I started using the 40” 5k in the office and the text clarity is so good Waiting out for black Friday to pick that up

No ips hdr models currently. The closest is Va miniled. If you want hdr for ips, it has to be miniled and I know no company that makes one. -I would also like one but they all moved to oled unfortunately. If you want just solid IPs without the hdr, you can check out Dell 40” 5k2k. That’s a solid work monitor and it can somewhat game due to 120hz. Lg has something similar but limited to 75hz. The only other options are Va miniled. The best though… they tend to have quality control issues… are the Samsung neo series. Neo is the Samsung miniled Va monitors. The Va for this is much better compared to the lower end. Not sure how much better but I don’t see people complaining about smearing with the monitor, only some with quality issues. The other option is oled. Companies are killing IPs for oled so that’s why it’s so hard to find a solid IPs ultrawide. Though not hdr, they were still good ips 144hz+ monitors for gaming and work. -you can still find them from lg but over priced for what you get and they are going eol… On oled burn in… it still exists but due to updates to hardware and software, it is much better than before. They should last much longer than previous oled but the issue still exists. It’s just the nature of the tech.

Well.. money is no object I assume, 38” tends to be expensive due to 3840x1600. Dell 40” 5k2k or lg version. If you want to half that price, check out innocn 40” 5k2k.

They should be basically the same but… Lg - 75hz Dell - 120hz They are not gaming monitors so if .. if you are thinking about gaming with them, they will work but not as well as the oled(this is way better but it should at least be mentioned) or even gaming IPs monitors. Also…. 40” ultrawide, I’m not sure if a curve is a requirement for this size. It may work fine without curve.

… it’s not the best ultrawide, it’s the best ultrawide for your use case. Dell 40” 5k2k ips - best work ultrawide. You really can’t get better at this time. 34” oled - 165/175hz to 240hz, many solid options here from lg, Samsung, MSi, Dell, asus….currently, I think the 341cqp and 341cqpx are the best of this category. 49” oled - 144hz to 240hz, same as the above. MSi has the 491cqp and 491cqpx which I am interested in. The new lg 45” 5k2k oled … it’s nice but I’m really waiting for a 40” 5k2k oled. I think that size to resolution would be amazing.

Dell 40” is the best monitor for productivity.

I have the 40 inch 5K2K from Dell. I run with 125% DPI scaling so my vertical productivity real estate is only 1600ish effective. That said, it's not a gaming monitor. It has poor pixel response time, even though it's 120Hz, and if you're coming from a nano-IPS with great response time, you'll notice the motion blur. It's still good enough for casual gaming, but anything competitive OLED or Nano-IPS would be better.

Dell's 5K2K has built-in KVM, that's the edge I'd give it over LG. Both use LG panels.

No. Also, which 40” did you use? Dell has a 40” 5k2k monitor that I’m currently using primarily for work. There’s also the 57” G9 if you find the 5120x1440p too short. 

If deciding between 49 in and 40in, an interesting fact to note is that the 40inch is only 7% smaller in overall area. With the 49inch, you sacrifice some height to gain more width. I personally prefer a 32in monitor height so I’d go with the Dell 40inch. With the 57inch option, you’d need to invest in a doc and have a powerful computer that can power the demands of the super UW. If you’re using it for a Mac, the Dell will be more satisfying imo.

Have you considered the 40 inch Dell 5k

I love that one so text is so crisp

I recently got a Dell 39.7” UltraSharp 5K2K and love it. I hooked it to my ThinkPad P1 Gen 6 (Nvidia A1000) via a Thunderbolt dock and am getting 120 Hz. Mainly for work but b/c of 3 grandsons have Minecraft, Fortnite, and Doom (I used to play that in the 90’s). Works fine for me 😎[Dell setup](https://imgur.com/a/KYHA8PT)

I’ve used different models across Dell, LG, Samsung, Lenovo, and Cepter for 49” IPS. I don’t think 57” is realistically anymore viable than 49”. Might be better to just double up (or more) on 49” if you need the real estate. The Dell Ultrasharp was definitely my favorite, but I recently picked up the Lenovo ThinkVision P49, and so far it’s giving Dell a run for the money. Albeit it is more expensive.
