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

The monitor itself has great picture quality. However there is one major flaw if you are a Mac user and that is the USB ports on the monitor will not work over the USB-C connection to the Mac. There is no work around I did plenty of research. I had to introduce a docking station in between the monitor and the Mac to get USB available. If you’re looking to use this monitor as a USB hub for your Mac look somewhere else.

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.

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...

Overall, a great product and experience purchasing this monitor. I really love the design. Super easy to setup multiple laptops to either share screen or swap quickly. Product arrived as expected and quicker then expected.

This monitor is exactly what I was looking for. Though it’s curve is more subtle than the others I was looking at, I find the screen very enveloping. I’m also less distracted than when I was using 2 monitors. Using with MacBook Pro, no issues at all. Bonus is the reduction of the cables & clutter on my desk.

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

Just got the monitor. It is excellent but I bought it to use with the USB-C cable with my laptop but the cable is missing. Contacted customer support and the only solution that they (the machine) gave me was to return it. I dont want to deal with that, I just want the missing cable.

Picture quality is great

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.

Awesome monitor!
