Dell U2414H monitor review and testing

American company Dell is a serious player in the market of computer accessories. The range of products is quite large and affects different areas of IT-industry, beginning from laptops and tablets and ending by desktop configurations and server equipment. A special place in this list takes monitor items. In this review we want to introduce you a representative of the series “U” (or UltraSharp) namely Dell U2414H model with a diagonal screen size of 23.8’’. Probably you know that 24-inch solutions today are the most popular and constitute a significant volume of sales on the market of monitors.

Packaging and content 

Dell U2414H

Monitor Dell U2414H is shipped in quite big cardboard box which provides protection against impacts and possible mechanical damages during transportation. The image on the front side of the package gives some presentation about the appearance of the device in particular the attention is given to the “frameless” case. Nearby, in the form of inscriptions and logos there are some of the features of the monitor. Let’s examine the set of delivery.

Dell U2414H

It includes:

  • assembled leg with stand;
  • decorative false panel for niches with connectors on the rear panel of the monitor;  
  • AC power cord;
  • USB-cable;
  • cable-adapter from Mini DisplayPort to a standard DisplayPort;
  • user manual and other documentation.

Looking ahead, we note that the model Dell U2414H is equipped only with digital interfaces HDMI and DisplayPort. Appropriate cables are not supplied, so you need to buy them separately.

Design and usage properties

Dell U2414H

Dell is very scrupulously approaches to the design of own devices and monitor Dell U2414H is no exception. It has a beautiful design due to “frameless” case and thin graceful leg. Decoration contains a mix of black and silver with a practical matte finish. There are no complaints for build quality: all plastic panels are quite durable and perfectly adjusted to each other. Top part of display for extra protection is covered with matte panel with anti-glare surface 3H.

Dell U2414H

Frames width around the screen is 4 mm, which seems that the size of its diagonal is not 23.8’’ but much more. Despite the internal layout of the power supply unit the thickness of the case is only 45.6 mm (without stand) which makes the model Dell U2414H one of the slimmest in its class. Monitor is equipped with holes for standard VESA 100mm. Thus, it can be mounted on the table and on the wall.

Dell engineers did not forget about functionality of the legs. Among all tested before solutions model Dell U2414H has the most adjustments: you can change the angle of the screen (-6,5° ... +22°), its height location adjustment (0 .. +130 mm) and orientation in space (portrait / landscape).

Dell U2414H

Furthermore, it is possible to rotation the monitor around its axis by 45° in clockwise/ anticlockwise direction. Regarding stability, also there are no complaints. Model Dell U2414H perfectly “feel” in any screen position: there is no oscillation during its operation. Note that under the plastic legs and stand there is metal. Swivel is also made from this material, so you should not worry about the reliability.

Dell U2414H

Video connectors are presented only by digital ports: two HDMI, one full-size DisplayPort and its compact version Mini DisplayPort. All graphics interfaces support a resolution of 1920 x 1080 at frequency sweep 60 Hz. HDMI ports correspond to MHL standard due to which Dell U2414H can connect compatible smartphones and tablets using the monitor to display stored content. We also note the interface DisplayPort Out and audio outputs for connecting external speakers. Built-in speakers are not available that is not so critical.

Dell U2414H

But model Dell U2414H is equipped with hub for four USB 3.0 ports. Three of them are located near the video jacks, and another one is outside on the rear panel. It has twice much electrical current in comparison with the others so if necessary it can be used for fast charging of mobile devices. In our opinion this solution for today is quite comfortable and practical.

Dell U2414H

Buttons to control the display and menu navigation are located in the lower right corner of the case and are represented as touch elements.

When you press each button, above them on the screen appears a little hint with icons that indicate the type of action depending on the situation.

In the corner of the case you can find a small indicator of the device operation. In the active display state it is white, during idle mode - flickers. In both cases the brightness is moderate and considered arrangement of LED does not distract the attention from the screen in the dark.

On-screen menu

On-screen menu is quite convenient and intuitive. It is caused by the traditional button labeled «Menu». In addition, the other sensory elements have improved functions of quick access to preset profiles, the brightness and contrast items.

More fine-tuning of the model Dell U2414H can be done directly from on-screen menu. Here you can optionally specify a balance of primary colors (R, G, B), set the gamma, sharpness and change the aspect ratio and select the input source.

Also, the user has the opportunity if necessary to reassign the actions performed by pressing the function keys.

Testing
Monitor has eight modes: "Standard", "Multimedia", "Movie", "Game», «Paper», «Color temperature», «sRGB» и «Ordinary color». Last profile is selected by default.

First of all we look at the indicators of profiles obtained during the test and then on the basis of the graphs in more detail will analyze the results.

In practice we have not seen the claimed brightness of 250 cd/m2. The best result was recorded at 220 cd/m2 after activation profile “Ordinary colors”.

In other cases (except the special mode «Paper») brightness varied from 165 to 200 cd/m2. However for normal operating it will be enough, but not for static contrast. It maximum value was only 237:1 at declared 1000:1. In competitive models it is around the level of 800:1 or higher. So instead of juicy and rich images on the screen you can get it duller version.

In all cases three components (R, G, B) are above the reference line of black color. The best-proven profile is «sRGB» with a mean range of 1.92 although “reference” index 2.2 is still far away.

Regarding the color gamut space sRGB, only in two modes it exceeds 90%, "Multimedia" and «sRGB» with values of 91.3% and 94% respectively. In the remaining profiles this figure is average. All diagrams have noticeable shifts of three reference points relative to the tops of the reference triangle.

 By the nature of the shift we can said that a supersaturation of color will be in light green, yellow-orange and red zones, and the lack in dark green, turquoise, pink and blue hues.

Although if we turn to the most important parameter, i.e. primary colors rendering accuracy, here Dell U2414H monitor shows pretty good results. When installing any of the five profiles (“Standard”, “Paper”, «Color temperature”, “SRGB” “Ordinary Color”) you get the same colors that were supposed to be in the original image. The best in this regard is mode “Ordinary Color” (selected by default), where the average deviation dE*94 (ΔE) was equal to 0.83, and the maximum 3.87. Let’s remind that considered acceptable values are ≤ 1,5 and ≤ 4, respectively.
In other words, the model Dell U2414H is not the best option for professional work with images and photos. However, for ordinary applications, games and movies its features are quite enough. The main thing is not to forget to activate one of the above five profiles. Note that the mode «Paper» is not particularly suited for long reading as brightness 101 cd/m2 is too high. To reduce the strain on the eyes, especially in the dark we recommend manually reduce this parameter to at least 50-60 cd/m2.

Now let's look at the remaining three profiles: "Multimedia", "Movie" and "Game".

Despite not quite correct transfer of certain colors and shades, they can be used when viewing movies recorded or digitized with high range. As you can from the above graphs, the red channel in profiles "Multimedia" and "Game" are undervalued. That is, if on the screen actors seem too "tanned", the activation of such profiles will lead to skin more natural tone. As for the mode "Movie", the blue channel which makes "cold" image is also overstated. In some cases this can also be useful, for example, when watching a movie with scenes abound with forests, snow, sea, etc.

However, we emphasize again that for everyday these modes should not be used.
