I purchased this item from Amazon based on Wirecutter's recommendation for the similar U2720Q and boy do I regret it. This monitor, while pretty, has been a disappointment on several fronts.
The monitor began exhibiting screen retention issues approximately 15 days after I received it. This included flashing of the display and a ghost image of Slack that would not go away despite plugging and unplugging my 2020 MacBook Pro into it.
Additionally the monitor will occasionally fail to successfully connect its USB hub through the included cable. While I will see my computer on the monitor, I cannot access of my peripherals until I reboot. It is currently unclear whether this is an issue with the monitor itself, or with MacOS, or some combination thereof. However it is frustrating.
I filed a warranty claim with Dell and the support rep put in a request to have a replacement shipped to me. I had to fill out a form to transfer the warranty from Amazon to me. I have documentation confirming it was successful, but support then denied the warranty claim saying I had to contact the seller. I contacted Amazon chat support and they told me to contact warranty@amazon.com which is an address that does not exist nor receives mail. I did eventually find warrantyquestions@amazon.com but that address has not responded to me either.
If you choose to buy this item, you should purchase it from Dell directly. However I would recommend looking at similar models from other manufacturers.
UPDATE
After using my faulty item for another couple weeks with my M1 MacBook Pro I was able to use the built in "LCD conditioning" tool to fix the screen retention issues. The default configuration for the monitor connects using USB 2.0 and this appears to be a root cause of the USB issues above. Updating the configuration in the monitor to use USB 3 (HBR 3) seems to have remedied the issue of USB devices not connecting the majority of the time. This does not excuse the support issues above, and I continue to battle with a incorrect resolution on monitor wake issue I can fix by unplugging and re-plugging the device in, but am upping this to two stars on the grounds the situation has improved.
