Excellent Monitor
Capacity: Dell Computer
There are so many YouTube videos, Reddit posts, and others creating confusion about this monitor that I decided to share my experience and potentially help others. My original desktop setup was composed of 4 23” Asus monitors. They served well, but after about ten years of service, It was time for a refresh. My first decision point was between getting a 16:9 43 Inch monitor like this Dell or going with an ultrawide 49” monitor. I did a lot of research between the LG / Dell / Philips / Samsung versions of these (43” and 49”) monitors, understanding all the features and differences between them. I resolved that a 49 Inches Ultrawide would not function well because for my work, having Vertical Space is more important than horizontal space. Having a squarer monitor is better for me. I can also divide this monitor into 4 1080p 16:9 regions, which is not true with the 49”. I was between the LG and Dell, I went with this Dell because of the build quality, the stand that adjusts vertically, and wanted the display ports. I also always had good experiences with Dell Monitors. Things I read and were untrue: 1) There is a drop in luminosity around the corner of the screen and the mouse is not visible at the corner. My monitor is perfect, and from the topmost leftmost pixel to the last pixel to the right, all of them have the same luminosity. 2) This monitor LCD is BGR instead of RGB, and fonts will look weird. I am using Windows 10 and required no configuration whatsoever. It works perfectly, and I have a much better Font and overall picture quality than my 4 23” Asus monitors. 3) The monitor is too big and difficult to see in the corners. I am using the Dell Monitor Manager software that allows for some adjustments without going fish for the monitor buttons on the corner bottom right. Still, I can create 4 distribution areas on the screen to “attach” Windows to them. I was a bit concerned because my 4 Asus were “toed-in,” this monitor is flat, but the IPS display is excellent, and I do not notice and difficult to see the distant corners. All looks the same. 4) The monitor is slow. Even found some Youtube video showing slowness. I have no issues with mine. The monitor @60HZ 4K responds as quickly as my computer can pump data into it. (just productivity software, no games though) 5) There is a “halo” around the screen. Yes, most LED LCS monitors also have this, and it is non-distracting or relevant. My Setup: Latitude 5401 I7/32GB/512GB Nvidia MX150 The laptop connects to the monitor via USB-C cable that came with the monitor I connected my Keyboard, Mouse, and Definitive Tech Incline Speakers to the Monitor USB ports. My setup came down from using 10 Cables (4 Power Cables + 4 DVI Cables + 2 Sound cables) to a Single USB-C plus the monitor Power Cable. I also connect to the monitor another Notebook (I7) using 2 DP, so I can share the screen in Half between the two computers or use just the USB-C to use all the monitor area. My eyes are 20 to 25” away from the monitor usually. I need to move my head a tiny bit to check the corners. But because I divide my monitor into 4 areas, I typically focus on a monitor region. Drawback: the only thing that would be better is if the multiple sources allowed 3 connections: 2 on the Top portion of the monitor and 1 large wide in the bottom. It does the opposite. There are many other different setups and configurations but not the one I described. Other notes: 1) Monitor Speakers sound great! (not even close to my Def Tech Inclines, though), you can select the source for the audio 2) Box if big, sturdy, and the monitor is very well packaged 3) Buttons on the bottom right are easy to find tactilely and operate. 4) This thing is heavy ... show more

Your whole workspace in one monitor.
Capacity: Dell Computer
I bought this monitor for pro use in my home office in 2020 to replace my triple $999ea 27" Apple monitors I used to run side-by-side. Been very happy with it overall. The ability to see multiple windows from a variety of different programs in one large view, rather than having to use 3 monitors to see everything I need to see in my normal workday is great for working professionals who use multiple programs simultaneously, like the Adobe Suite for example. The monitor does not come color calibrated for OSX however. (Mine didn't anyway.) To fix this, I downloaded the OSX GAMMA CONTROL app, so that I could manually adjust the colors, brightness and gamma to color calibrate because its native white point. That inexpensive app works perfectly for calibrating your colors and white point, particularly important for Photoshop use. It's really a great monitor, and at about a 3-4 foot distance, immersive and works perfectly with a MacBook Pro, however, I wish they would ditch the outdated HDMI, Display Port and USB 2.0 connections in favor of additional USB-C ports rather than appease luddites with old USB 1.0 plugs that are phasing out. My next monitor in the future (when someone decides to build them) would be to size up even more to a 55" curved 8k display, provided it costs under $2k. All in all, great monitor, great buy, great experience. Thumbs up. ... show more

I think this may be the best monitor I've ever owned. Flawless in performance and clarity. I'm an IT professional and I spend 12-14 hours a day in front of my computer monitor. I'm also at that age where my near sightedness is suffering from whatever it is that hits you around 40-45. I get the geography and the ability to scale my screen up significantly without losing screen real estate. I definitely needed this and although it addresses my own aging deficiencies, this would be a remarkable monitor for anyone that needs to be IN their work and not just staring at it. ... show more

Big; impressive; useful for certain applications
Capacity: Dell Computer
For my use in a home office environment it is great, with just a few quibbles. Here are my recommendations and my thoughts on the monitor, plus what I wish I had considered before purchasing this monitor: 1. Don't try to look at everything on screen all at once. Use the Dell Display Manager to divide your workspace into snap-to grids so that you can position your windows in a way that helps you be productive. I like to have my Microsoft Word Doc (in two page mode) right in front of me at a comfortable eye level and then I arrange the other windows (a Word doc in single page view, Google Doc, email, and reference materials, etc.) in my peripheral vision where I can turn my head to glance toward them if necessary. I usually use Word in two-thirds of the screen on the left and divide the right third into two or three squares for my other windows. Sometimes I divide the monitor into four sections while multi-tasking. I almost never have one window fill the entire screen unless I am using Photoshop or Lightroom. 2. With all of this screen real estate, it can be like staring into a lamp when you are on white pages. To reduce glare, I set my Word program, web browser, and other applications to dark mode. I also reduced the brightness a bit. 3. Again, with such a large screen, it is like looking into a lamp, so to cut down on all the blue light, I recommend selecting the Comfort View mode in the Dell Display Manager. It makes the screen less blue (more sepia) and you can use other controls to dial in how you like it. Turn off the Comfort View if you are editing photos or doing work where color accuracy is important. Image color and clarity in Adobe Photoshop and Lightroom look beautiful on this display. The stand for the monitor assembles easily (just a snap) and it has great adjustment abilities like the other top Dell monitors do. So, what do I wish I had considered before purchasing this monitor? The pixel density. Most of my time is devoted to reading and writing text and I think that if this monitor had a higher pixel density, then the text might be more enjoyable to view. The pixel density of this 43" Dell is 103ppi. It does not look as crisp or have as nice of a contrast as my Microsoft Surface Laptop 3 with the 15" screen that has a pixel density of 201ppi. I will enjoy using the Dell 43", but when the Microsoft Surface Studio 3 comes out in 2021 with a pixel density of 192ppi or possibly greater (the specs have not been announced yet as of December 2020), then I will probably sell the 43" Dell and switch over to the Surface Studio to give my eyes a present. ... show more

[Short term] Decent hardware. Even works with a Mac (details inside)
Capacity: Dell Computer
No complaints about the monitor itself (classic Dell monitor quality). Works with Linux, Windows, and Chromebook boxes with no problems whatsoever. The most useful feature is the 90W power delivery via USB-C the video is delivered on - saved a port on a laptop, now can run two monitors on it with no extra hardware. The only quirk I had to deal with was not related to Dell hardware, but Apple hardware. Mac laptop adamantly refused to recognize this display as anything else other than what was previously connected to it, which was running at 2560x1440 (I see this is the problem a lot of people have). Contrary to what you'd expect from Apple in 2021, in order to fix this you have to POWER DOWN the Mac while having this monitor is connected, and then turn it back on - the monitor is properly recognized at that point, and keeps chugging on at 4K resolution merrily ever after. Beware this monitor is HUGE. It will interrupt your line of sight, and if you are used to looking at the room over the monitor - keep in mind that this will no longer be possible without a serious posture adjustment. ... show more

Great monitor for the money. 3-4 years ago, these things were twice as expensive.
Capacity: Dell Computer
This monitor is a monster and definitely worth every bit of it. I'm getting older, and it sure helps me to see multiple windows. I like it a lot better than back-to-back or dual monitors next to each other. It's definitely worth the money.

Great for office work
Capacity: Dell Computer
I bought this monitor to use at home for remotely doing office work. The text is crystal clear and the amount of screen real estate is incredible. The brightness and crispness of everything on the screen is amazing. I can see Excel spreadsheets now on one screen that used to require a lot of scrolling. I don't do gaming; so I can't comment on that. The setup was extremely easy. I used the included USB-C cable to connect the monitor to my laptop (which also has a USB-C port). Note that the USB-C cable that Dell includes with the monitor is extremely short. It was just barely long enough for me. You may need to buy a longer USB-C cable, depending on your use. The seller was great and processed my order within hours. No problems whatsoever. I wish all of my purchases were this smooth. I've never had a 4K monitor before and I was concerned that everything would look too small, even on a monitor as large as this. But the upscaling (for text) works great. I currently have mine set for 150% in the Display Settings so that text appears a little larger. It's very easy to play around with the settings until you find the setting that's best for you. In fact, the default setting was 300% which I thought was way too large. Yes, this monitor is somewhat expensive. It's a brand new model that was just released a few months ago. I have no regrets about the price and believe that this one is actually cheaper than trying to find multiple smaller monitors to set up in a dual display configuration to give me the kind of crispness and trouble free experience that this Ultrasharp model has. I've used Dell monitors for over 2 decades and feel comfortable sticking with their Ultrasharp line because I know that they are built to last. ... show more
