Dell UltraSharp U4919DW 49″ Monitor Evaluation

We are not sure if Super-Ultrawide is the official term for this type of display, but they are wider than a standard Ultrawide, so we believe that it works somehow well here. Maybe twice the width is better? In any case, the UltraSharp U4919DW, the latest Ultrawide monitor from Dell, is very wide and overall quite solid.

In terms of specifications, it's a 49-inch monitor with a 5120 x 1440 resolution and 32: 9 aspect ratio. Now you may be wondering why someone would want such a wide monitor.

The answer is simple: this display corresponds to two 27-inch 1440p displays side by side without an aperture in between. So if you are planning to work with a 1440p setup with two screens, the U4919DW may be a better choice.

Properties and design

This is one of the first nationwide 1440p displays on the market. We have seen 1080p class (3840 x 1080) displays for some time, and some even do a high refresh at 144 Hz. However, we are only now seeing 1440p equivalents coming onto the market. So it is a new panel type and a new product category.

Of course, some of the features available on 1080p class superultrawides are not yet available on the 1440p models. One of them is the high refresh rate. There are some models that are slated to be released this year, but we're currently stuck at 60 Hz. The other is any type of adaptive synchronization function. So what we have left is a monitor that is designed more for productivity and creative use than for games.

We think this resolution is promising for games, but it is also very good for working and multitasking because there is so much screen space. And unlike 1080p class variants, the resolution is very good, which in turn helps to load the screen with apps and display crisp text and images. If you're tired of the frames and all the other complications associated with dual-screen setups, something like the U4919DW might be what you're looking for.

Dell has used the standard UltraSharp design language for this 49-inch animal, so that most of the outer shell is made of simple, gray, office-grade plastic. It looks good and Dell lets the display do all the talking.

What impressed me more than the visual design is the build quality in general. The monitor is extremely heavy and getting it out is more complicated than most of the displays we tested. However, the end result is an extremely solid product. The stand is hideous and makes a great contribution to stabilizing such a wide display without wobbling. It also has a solid height adjustment and tilt function.

In addition, the U4919DW is curved with a relatively slight 3800R curvature. Sometimes this can lead to complications in the building process, leaving a few messy seams here and there. Not with this ad. It's very well built and we wouldn't expect anything less from Dell's UltraSharp line.

For connections, we get two HDMI ports, DisplayPort and USB-C input, as well as a number of USB inputs and outputs, one of which supports charging and two are easily accessible at the bottom left. USB-C is another nice innovation in the office, since it is easy to connect a laptop with a single cable: in return, the monitor even delivers 90 W charging power.

The only downside to the design are the buttons that control the on-screen menu. Dell uses basic face buttons instead of changing direction, making menu navigation difficult. Still, there aren't many functions in the menu at first, so you probably won't use them too often.

Dell has added several zoning options to take advantage of all of these screen areas. In the picture mode there is a basic picture so that you can connect two 16: 9 1440p inputs and each occupy half of the display. However, the software utility is more impressive: it allows full zoning of the entire display in any configuration, making it easy to insert windows into layouts that Windows does not support inherently, e.g. B. three. However, this is just one of 38 presets in the app that you can use to create any zoning array. It is a powerful tool that makes optimal use of this display.


Now if you go into the "Performance" section of the review and this is a productivity-oriented monitor, most of the metrics that we will examine in detail are focused on color accuracy and the like. According to Dell, the monitor offers 99% sRGB coverage and less than 2.0 DeltaE accuracy.

In terms of panel technology, the 49-inch screen is an IPS-LCD, which is the standard for professional monitors. The reason for this is that despite modest contrast ratios, IPS enables the best viewing angles – which is crucial for color-accurate work – together with superior uniformity. The contrast ratio of the U4919DW is not bad at 1160: 1. This roughly corresponds to the upper range of the performance of IPS panels. The brightness is also suitable for most applications with up to 330 nits. The area I was most impressed with is the excellent viewing angles you would expect from a high-end IPS like this.

Standard performance

We admit that we were a little surprised when we first ran the tests with the out-of-the-box configuration. By default, the monitor uses the standard mode, which Dell has calibrated for sRGB. However, the white point is switched off instead of clocking at 6500 K. The CCT average is 7404 K with a white point of around 7000 K. This gives the display a slight bluish tint compared to the correctly calibrated monitors that I use every day.

This type of result is not terrible, but it does result in a grayscale deltaE average of 3.14, which is higher than the ideal DeltaE below 2.0 for content creation. The gamma curve is decent, which is easy to see. I'm not quite sure what happened to the white dot here, but we'll fix that in a minute

Before that, however, we ran our color tests that more closely match the brand that Dell is promoting. The monitor achieved a DeltaE average of 2.09 in our saturation test, but the monitor only has problems with low saturation values. And in our general ColorChecker test, the panel creeps in with a DeltaE average below 2.0.

These color tests are good, not the best we've ever seen, but definitely accurate enough for productivity and creative use without the need to invest in calibration tools. Grayscale is definitely a problem, but the colors are good.

Easy OSD calibration

Unfortunately, there is no nice, simple solution to correct the grayscale curve. Since the monitor appears to be calibrated taking this white point into account, the colors will be out of balance if we set the white point to a more accurate 6500K. You can see this here: the CCT average is a reasonable 6588K, although it is not perfect, and the DeltaE average is 2.55, so improved. Then when we look at the ColorChecker average, it's close to 3.0, where it was previously below 2.0, and that's because of this color shift when we pull the white point back to accuracy.

We are not quite sure what happened during the factory calibration or whether this could only be a problem with our device. My results were also slightly worse than the calibration report included in the box, although this report still has a grayscale CCT of around 7000 K and my tests require a lot more data points. And overall, performance is decent, especially for general productivity work thanks to this color deltaEs around the 2.0 mark and full sRGB coverage. Only for creative workloads like video or photo editing do I go to the next step, which is a full calibration.

Complete calibration

With DisplayCAL, we were able to achieve excellent performance very quickly with this panel. This is one of the great advantages of IPS technology as it works very well when calibrating. In fact, the contrast ratio rose slightly to 1200: 1 after performing this calibration, with all DeltaE values ​​below 1.0.

By default, the uniformity is very good for such a wide panel. There are some problems with the outer edges, but the central zone, which is massive for a monitor of this size, is well above average. This is another reason why you choose IPS for productivity or creative work.

Above: standard uniformity. Below: homogeneity with homogeneity compensation

However, the U4914DW also has a uniformity compensation option that further improves uniformity. This improves these outer edges and essentially ensures perfect uniformity across the display. Still, it's not actually a mode that I would use, as it bizarrely affects color and grayscale performance completely. Switching the mode on halved the contrast ratio, causing color deltaEs above 5.0 and butcher grayscale. I am really amazed at why this is the case, but it works as advertised to improve consistency. Perhaps these are the compromises necessary for the uniformity of the prefects? In any case, it is not worth it.

Finally, we only want to briefly review the response time metrics. This is not a particularly fast panel with a gray-gray average of around 9 ms. However, this is fine for a 60 Hz display with productivity focus. There is a single overdrive mode, but it has introduced an overshoot. Therefore, the standard option is best suited. The UltraSharp U4919DW also achieves an input latency of approx. 7 ms. This is not the case with gaming displays, but it is perfectly acceptable for this type of monitor and is not disturbingly slow.

closing remarks

The Dell UltraSharp U4919DW is aimed directly at productivity, office use and creative professionals. For these usage scenarios, we think this monitor does many things right. It is reasonably built and very robust, has useful functions for office users like the USB-C power supply and uses an IPS panel, so that we achieve an excellent uniformity and viewing angle.

Factory calibration is good, not perfect, but we think it's fine for offices, although anyone who does color-accurate work should still strive for independent calibration.

This national form factor also offers many advantages. Replacing two 27-inch 1440p monitors with one may be the right solution for your workflow. You may hate bezels or the inconvenience of placing two displays in a row. Most importantly, you can make sure the content looks exactly the same on both halves of the display, which you don't always get with separate monitors. Overall, I think this is a much better option for productivity than a 1080p class equivalent. The higher resolution of 5120 x 1440 makes a big difference.

Gaming is not the intended market for this monitor, and even if it does have some cool new specs you might want, we wouldn't recommend it for this purpose. Over time, 1440p Double-Wide will become an option for games without the limitations of a maximum refresh rate of 60 Hz and without adaptive synchronization.

Dell sells two UltraSharp 27-inch 1440p monitors for $ 350 each, or two with PremierColor for $ 550 each. Both options cost less than this $ 4950 super ultra for $ 1,350.

Paying a premium for newer technology isn't unusual, is it? For many, the benefits of a single panel don't outweigh the huge price hike, making the U4919DW a niche, high-end offering. However, if you really want to take advantage of the specific benefits of this single panel solution, this is a quality option that should be taken seriously.
