Great monitor for the price

This is a great monitor for the price. I'm sure you can find a better monitor, but you won't find one for less than $500. It's interesting that they show it with a curved screen, but it's definitely flat, which I prefer for a work monitor. (not playing).

Budget 4K display Poor Really well done, but there are critics. First I got a panel with a stuck red pixel; which never went away despite several recommended methods to get rid of it. This is only noticeable in very dark images, with such small pixels it is only a spot. It wasn't worth the risk to return/exchange and get something worse. There are some issues with ghosting and smearing on darker images in games, but that's not bad for a general-purpose monitor. I encountered an afterimage with…

Great monitor - my new review

Very easy installation, height adjustment by simply sliding the monitor up and down, excellent picture quality. I think Dell is protecting its reputation. All in all a very good monitor at a reasonable price.

Great IPS 4k display for the money

This Dell 4K monitor is excellent quality with minimal to no black light distortion, it's actually hard to see from any angle. It also has a higher contrast ratio (1300:1) than comparable displays in the same price range. I think that's a pretty good deal for the money. For context, I've had various Dell monitors ranging from 24-inch Full HD (S2340M) to 27-inch WQHD (U2719DC). While I miss the USB Type-C port on this particular model, it costs an extra $200-$300 (at least for me) to get a…

Great secondary screen for MacBook Air

I bought it for my son to use in college with my MacBook Air when his work needs more space like long documents and spreadsheets. I really liked the square base of the stand, especially with limited desk space. I also like the stand's tilt and height adjustment features. It's actually pretty hard to find. The viewing angle is very important to prevent fatigue. He's been using it for about a month now and he loves it. He says he can set it up as two separate screens when using his laptop. I…

Good quality cheap monitor. Could use some improvements.

macOS users please note that this monitor will force you to switch to YPbPr mode when connected via HDMI. In order for the device to recognize RGB correctly, you must connect via Display Port. When connected via DisplayPort, you cannot scale the display without the display flickering. The default scaling for a 27" monitor is 1920 x 1080. This monitor does not support macOS through the Dell Display Manager software. Maybe a $45 USB-C to DisplayPort adapter could solve this problem, but I haven't

I really like this monitor. great screen at a great price

This monitor works with an HDMI to USB-C cable that I purchased previously (60Hz) so it just plugs into my MacBook Pro - no cumbersome adapter required. NOTE. I am not using the HDMI that comes with this monitor. Another review states that the HDMI cable that came with the monitor is not a good cable. The stand is not height adjustable. But it is very easy to assemble and disassemble for collecting on the go. The perfect mobile monitor for my needs. I mainly use it for book editing and layout -

Great monitor that deserves Dell's best cable

The monitor is excellent but the cable is of poor quality. Other reviewers have mentioned this shortcoming, which helped me fix the issue. I have a Surface laptop connected to a Microsoft Dock and dual monitors. The HDMI cable provided by Dell does not support 4K resolution. I've tried several other HDMI cables and the best resolution I could get was 1920 x 1080, well below 4K standards. Finally, I bought a DisplayPort to Mini DisplayPort cable, connected it to the docking station and a Dell…

SOLID 4 STARS!: my rating

I love this monitor. It's not the best option for gaming, but it gets the job done for a decent price of $319! I love that it adds a dual screen to my computer.

Not a gamer, but excellent image quality

I have a couple of old 27" 1080p monitors at work but need an adequate monitor for my home office. I decided to switch to 4k - the best solution. This monitor is really good. It goes beautifully with my MacBook Air and my work computer. to assemble - no tools required very easy to assemble and much better quality than i have had so far i have nothing bad to say at all.

Stunning 4K monitor.

This is an excellent monitor, from the design aesthetic to the display quality. The only thing I would like to point out is that if you select the monitor as the audio output in the computer's operating system (I'm using Windows 10), the sound comes out both through the monitor's speakers and whatever you may have connected will monitor the audio output (e.g. headphones, external speakers, etc.). All you have to do is set the volume to 0 or disable the monitor speakers in the monitor itself.

I love this monitor but it is NOT curved like the picture shows.

We were so disappointed that this monitor was not curved. This was our main selling point as I am a photographer and needed something easier on the eyes to edit with and I have a gamer who will be using this monitor for gaming. We decided to give it a try anyway before messing around with returns. We love it even though it's a flat screen. I feel that you should change me

Started blinking sporadically.

At first glance, everything is fine with the monitor. It works great with my Macbook, there is some shading around the edges but I think it's ok for the price. The bad thing is that after a month of use it started flashing like an analogue TV. and it happens every now and then. When I go into LCD conditioning mode, it stops after a while.

Great for 4k streaming

Since purchasing this monitor I have been streaming 4K content on YouTube and have been blown away by the quality. I also stream Disney+ shows and movies on it. This is a great purchase.

Great everyday driver

I consider Dell to be a trustworthy brand, which is why I chose this monitor to try 4K for the first time. The design is nice and clean without any flashy "gaming" accents. The fully adjustable stand is a great addition and works well. The screen itself has an excellent picture and high pixel density. Build quality is solid, as I'm used to from Dell, and I can't fault it. Perfect for anyone looking for a good all-rounder for their computer without spending a fortune.

Great for Macbook Pro

I agree 100% with other reviewers who said this is the right monitor to pair with a high-resolution MacBook Pro with Retina display. I have tried other monitors before and had horrible blurry images but not with this amazing monitor. The image is crooked and incredibly high resolution. I have many options as to how much I want to fit on this great monitor. I'm very satisfied!

Fits perfectly on my late 2015 MacBook Pro

I received this based on a review from rtings. I had a smaller Dell 1080p monitor that I was using with my late 2015 15 inch MacBook Pro and needed something to match the quality of the Mac screen. I originally used a mini display cable to the HDMI port, but that was a mistake because I couldn't stream 4K to HDMI via the mini display port. Then I got a mini displayport for a displayport cable and something else. The monitor looks so good. I only use it for work, but I can say that the picture…

Dell is a boring brand. Yes!

There were a few good pros, but they were overshadowed by the cons, and regardless of your own assessment of the pros and cons, the item was also defective. Main problem: intermittent signal loss - about every 5-30 seconds, the screen appeared as if the HDMI cable was unplugged. Many have reported this issue in these reviews and elsewhere on the web (PS - I was using a Windows device, not an Apple/Mac). As soon as I set up the monitor the problem started and Dell support didn't offer any…
