Rated 5 out of 5 by Thibaud S. from Very good 16:10 monitor Received a week after the online purchase. Very good monitor, with great connectivity. One of the few monitors with a 16:10 aspect ratio, perfect for work-related application.

Rated 5 out of 5 by HumanGenome from Great monitor, bad driver/software support The monitor itself is great. Unfortunately the driver support is very outdated at this time. The monitor has trouble coming back from sleep (not hibernation) after a period of time. I also have them daisy chained and sometimes when it comes back from sleep the daisy chained monitor has to be turned on/off. On top of this, the Dell monitor software that comes optional to configure the monitor settings causes system crashing and instability - had to uninstall it. This monitor seemed very rushed to market.

Rated 5 out of 5 by Buffy Navy from Ok monitor?Awful sales support It is a nice monitor but does not match the optiplex computer I bought, which was my primary request. Different size, different shade of silver. They should have just said there was not one that matched to purchase for my second monitor. Customer service is all apparently in Asia now. I miss talking to people in America.

Rated 5 out of 5 by Michael from Poor Panel Quality Unfortunately there is a lack of 16:10 monitors in the marketplace and while I'm glad Dell still offers this ratio, this particular monitor, from a visual quality level, fails terribly. I've had multiple Dell Ultrasharps in the U24 series and have always been pleased with them, they had good colors and detail and I still use them. My main monitor is a Dell UP3017. So I do know what Dell is capable of building and how they should look. What I believe happened with the U2421E is that Dell switched suppliers of the panel to a cheaper one and this was a big mistake. The new panel has poor colors and visual artifacts such as fine lines showing up in certain colors (think interlacing artifacts). It basically looks like a cheap laptop screen. I went through the process of exchanging the monitor for another one and it still had the same issues. I finally returned the monitor for a refund. Luckily this process was pretty straightforward with Dell. I do hope that Dell looks into this and decides to again make these monitors up to the quality standards they should be. Even if they had to charge a little more money.

Rated 5 out of 5 by AMM from Good monitor, but it could be better Good monitor with 16x10 aspect ratio that is comfortable for work. Unfortunately Dell is not making high resolution monitors with this aspect ratio. Would be nice to have 22" or 24" or 27" monitors with 2560x1600 resolution. On the downside of this monitor, I have to say that the bezels are bigger than a 4 yrs old monitor I bought from Dell, which is very disappointing, especially because I use several displays side by side, and small lateral bezels are very important for me. Also, the build quality is not as good as it was in comparison with previous generations (U2414, U2415, etc.)

Rated 5 out of 5 by John R. from I would not buy this model again. Grainy text, uncrisp images, blurriness on video playback. Verified monitor settings, correct driver, and that monitor is not defective with Dell Technical Support. Used with USB-C cable on 2017 MacBook Pro.

Rated 5 out of 5 by Aero from Excellent Monitor Excellent Monitor, Color, Pixel depth, forget 1900x1080, not really good for working with large spreadsheets, and multiple documents on same screen. This monitor and its predecessors have been the best since introduced. Now lighter. Have two used to provide large work area using separate apps on each screen or have multiple spreadsheets or multiple documents open to support analysis of data or comparison of documents.

Rated 5 out of 5 by Magnum from I am addicted to 16:10 screens!!! This is my fifth Dell 24" 16:10 screen. My first one was purchased maybe 10 years ago and my parents have that one for daily use. They are in their upper 80's and read daily digital news papers every day with it. I have two monitors side by side at work that are used 6 days a week. They have some years on them but I love them compared to the 16:9 screens that my employer supplies my fellow workers. I bought my own monitors just for my satisfaction after using 16:9 screens. I upload images to online internet listings and do a lot of Excel spreadsheets. I just purchased a U2421E for home to finally set up a side by side for personal use. I have been looking at the 30" Dell 16:10 screens for several years as I wanted something bigger so I could have a spread sheet on one side and my online bank screen on the other side. Able to do this with my one 24" screen in Windows 10 but it was awkward and small. With the prices of the larger Dell 16:10 so high even with sales, I went with a second monitor. The color is very good and I do have a color calibrator at home as I do tweak photos for 16 X 20 prints. Lots of ports but I also have plenty of ports on my old Dell 8920 XPS desktop that still works great after 5 years. It cost manufacturers more to use 16:10 screens than 16:9 screens but I hope Dell keeps this model going for years. Very few 16:10 offerings.

Rated 5 out of 5 by ShrewsUser from Sharp Images But Flaky Connection Images are sharp as promised but the screen occasionally goes dark like it?s rebooting. The connections are as tight as I can possibly insert them and I can?t find any new drivers that will fix that.

Rated 5 out of 5 by Ed F. from If you need 1920x1200 resolution, this is the monitor. This monitor is definitely worth the money. I did plug and play, even though the included literature stated that it may need driver updates, and it worked perfectly. Beautiful, sharp display!

Rated 5 out of 5 by Disappointed from Missing items/poor customer service response I received this monitor several weeks ago but have not been able to test it because of a missing power cord. I have reached out the customer service and they have been extremely slow to respond. Very disappointed to that I am missing items and with customer service- beware that support is extremely slow to respond and take action!

Rated 5 out of 5 by Oun Kwon from Be happy with it, but. Monitor quality is excellent. Optimal screen size for a desk top monitor. Versatile postilion adjustment (tilt, swivel, up and down etc.). Design Problem: adapter ports on the back are flush with the back and make difficult to plug in cables (video cable, USB devices, etc. The monitor comes with a video cable. Mine was found faulty. E-mailed to Dell 2 x but never received answers :-<

Rated 5 out of 5 by Kevin Knauss from Versatile Monitor Moving from a notebook computer, the UltraSharp Dell monitor is nice. It has lots of real estate to have multiple windows open so I can read from one document and type it onto another. The HUB is working great. I have a little speaker plugged in that daisy chains to ear buds and a mic. I also have a camera plug into the Hub in case I have to do one of those Zoom calls. My only wish is that I would have ordered the monitor that swivels horizontally.
