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

I have had this for a year. Was very happy with it. Quality was great. All of a sudden now the screen is starting to shutter. I’ve checked cables, I hardly ever touch it, use it just for work. Not thrilled for how expensive it is to now start to be dealing with issues with the screen. Not thrilled. Need to now find someone to look at it to figure out the issue.

When the monitor arrived and I used it for a few minutes, it flickered wildly. With lots of web searching, I found that by reducing the response rate of the monitor and using LCD conditioning, I was able to reduce the flickering. The flickering is a well reported issue for anyone using this monitor with a Macbook. Dell does not support this monitor with Macs. In fact, they dont support most of their monitors with Macs. So, they were of no help for me in dealing with the issue. Summary: do not buy if you are planning to use this with a Macbook. Its working for me for now, but I dont know if it will stay that way; and I know Dell will not help me if it doesnt.

The monitor is great and works as expected but sometimes I get black screen for few mins. I have port cable but same issue. I gave it 4 stars just for that reason.

Received the monitor, opened and it did not work… called the Dell supper with the service tag and they mentioned it’s invalid product and doesn’t have a record of it.. beware what you buy… this is so disappointing that Amazon is selling these as new and original

I use this monitor for my work. I am a software engineer and need multiple software/programs running which I can see simultaneously. Picture quality is great, no configuration hassle and overall the monitor looks really beautiful on my desk.

Monitor is really nice and Super bright. In my opinion it is the perfect amount of screen space for most users. The particular one I received had a little flickering and caused eye strain so I sent it back. I am guessing it is something with the one I had and not an inherent problem. Have not reordered a replacement yet.

I received the monitor and tried to register it through Dell to confirm that I was eligible for their standard (and highly regarded) 3-year warranty on all new products. However, the service tag (the unique code Dell uses to track the products they sell) is invalid, so Dell does not recognize this unit as a valid Dell product. So Im not sure if this monitor is a bootleg, or the seller acquired them illegally or what, but I do know that it means no warranty from Dell. I see that some other reviews mention the same issue so I know its not unique to the unit I purchased. I would highly recommend purchasing this monitor directly through Dell - a little more expensive but worth it to avoid future headaches. I dont know why Amazon allows 3rd party sellers to sell illegitimate products on their platform...

Decent for working, good picture quality and 65W usb c

This is a gorgeous monitor, elegant and professional looking. I can’t stop looking at it. Lol! Set up is a breeze, was able to do it all on my own in 10-15 mins. I connected it to the display port and I was able to use it right away, no set up needed. No dead pixel, no bleeding, no IPS glow. Day1, it felt a little too big though I am coming from three monitors - 17/19/20”. But the next day it feels normal and it has so much real estate that I don’t miss having multiple monitors. I use the comfort view preset mode and it’s really easy on my eyes. I don’t need to use my blue light glasses anymore. Brightness is really good, I had to reduce mine from 75% to 53% cause 75% was too bright for me that I felt I was getting headaches (I have sensitive eyes to light). I use this monitor for work only - mostly emails and spreadsheets and it’s really pleasant to use. Text is sharp enough for what I am using the monitor for. Can’t complain with the pictures either though I do not use this for photo/video editing. It doesn’t have a speaker but I am planning to get the Dell slim soundbar soon. I haven’t tried the KVM/PIP/PBP features because I don’t have the need to do so as of the moment. My only minor complaint is that it’s hard to reach the ports at the back of the monitor. I have mine set up close to the wall and when I tried to use the HDMI/USB-C cable to test them, I had to move the entire monitor to see and reach the back. Also I wish it’s a little more curved, but I didn’t want to spend $300-$500 more for the Dell U3421WE model. So I decided to go with this P3421W monitor. I really want to stay with Dell monitors because of the quality. I have a sit stand desk and a very stable stand is a must so it won’t fall forward or move everytime I adjust my desk. And 3600R is not bad at all. It’s still comfortable to use, I can still see all corners without moving my head which is important to me cause moving my head left to right (even little movements) strains my neck. I love that height is adjustable, it tilts and swivels too. Makes it easier to customize for a more comfortable position. Yes, I’m very happy with my purchase!

If you are wanted a great monitor for the imac mini this one is great. I really love the monitor. Running at 60hz it meets Apples requirements. If you are thinking a 120hz monitor is better, those are not compatible. This is the one to get. Some things to know, the PBP works good but the monitor switching is done using a hardware switch like joystick. The software to manage the screens is not designed to work on mac or linux. But there are some third party open source options. I found it just easier to have more then one keyboard for multiple computers in a mixed OS environment. You may be able to get the drivers working easier on linux. Running 3440 x 1440 on the M1 imac.
