Dell 34 Inch Ultrawide , WQHD (Wide Quad High Definition), Curved USB-C Monitor (P3421W), 3440 x 1440 at 60Hz, 3800R Curvature, 1.07 Billion Colors, Adjustable, Black

It didnt work for macbook air 2021. The mac couldnt recognize the usb-c port. I tried replacing the cable and with a different mac. Always received a message from the monitor that there is no source.

The computer monitor has bad power input and flickers when on low brightness / contrast. Absolute waste of money.

Great monitor and the built in KVM allows me to switch between my MacBook and my Dell

Awesome monitor!

Not the best pixel density (not in par with Macbook screens, as you should expect) but good quality screen overall. Built sturdy. Matte screen. Easy to adjust for your desired height and angle. Swivels horizontally.

The monitor is fine. But when I tried to register it with Dell for warranty support, the Service Tag was invalid. This indicates that the sale of the monitor from Dell to the reseller was never registered. I went around-and-around with several Amazon agents, Dell, and the reseller. The reseller couldnt help me because this order was Fulfilled by Amazon. Dell told me exactly what Amazon need to do, but of the several agents that I was transferred around to, none of them had a clue what I was talking about. Now, I am very suspicious of how this monitor came into Amazons possession. Perhaps that explains why it is so much less expensive here than at other (more reputable?) resellers...?

So far so good, I use this with the 16” MacBook Pro and have had no issues with the monitor and it doesn’t get hot charging the MacBook. Picture quality seems great but I am primarily using this for large spreadsheets.

Very pleased with this monitor now. Even though I cant run it at full resolution due to my ancient nvidia GT3somthing. Even at 2560x1080, the picture looks great. Usually when you run a monitor lower than its native res, it looks really grainy. This one, while not as sharp as the full res, does not look all that grainy. My big problem when I first plugged it in was that my mouse was extremely jumpy. I look all over for help and solutions and found none. Everyone said it was the mouse driver, which I knew wasnt true because when I lowered to 1280x1024, the mouse worked perfectly. Dropping down to lower widescreen resolutions didnt help though. So I spent some time messing around in all the various settings apps and discovered that nvidia, by default, was treating this as a television. Meaning refresh rate was 24hz! No wonder my mouse was so choppy. So I changed it from TV to monitor mode and it brought the refresh rate up to 30hz at 3440×1440 which was better, but still choppy. So I switched to 2560x1080 and that brought the refresh rate to 60hz. And now my mouse is perfect again. So, I guess I have to get a new computer to take full advantage of this monitor. But Dell or nvidia or microsoft or somebody should change this monitor profile to default to monitor mode. Not TV mode.

Excellent screen for productivity. Replaces 2x my old 22 inch screens and feels much better. Brightness, colors and picture quality is excellent. Looks great on the table.

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!
