Monitor Dell UltraSharp U3014: review and testing

Dell UltraSharp U3014 is positioned as a solution for demanding users and professionals. That is not just talk. Dell has equipped its monitor with really high-quality AH-IPS-matrix with resolution of 2560 x 1600 pixels and provided factory calibration, then the average deviation dE*94 should not be more than two points.

In addition, the Dell UltraSharp U3014 offers a wide range of interfaces and a considerable number of advanced features designed to make working with the monitor more comfortable and effective. Moreover, it uses not a conventional WLED-backlight, but GB-LED that is white LED s are replaced by blue and green with additional use of red phosphorus. This allows to increase the range of wavelengths of light that is transformed into an expanded color gamut.

And now let's see how all these promises are true.

Design and operation conditions

Dell UltraSharp U3014

 

Model Dell UltraSharp U3014 is presented in black color with small gray patches. The entire case is plastic, in contrast to the inner part of the stand which is mounted from the metal to increase the stability and reliability.

Dell UltraSharp U3014

 

Unlike newer Dell monitors, the model under consideration has strict design, typical to older solutions of the company.

Dell UltraSharp U3014

 

Due to the use of LED backlight monitor is not very thick and could be quite lightweight. But take into account three-kilogram stand with metal base.

The build quality and fit of parts is at high level: you won’t notice squeaks or backlash. Visually case also leaves a good impression: the solid design is reinforced by the use of opaque materials, so Dell UltraSharp U3014 looks quite professional.

Built-in "micro lift" allows the monitor Dell UltraSharp U3014 move in a vertical plane within 90 mm. Tilting is provided by the joint between the stand and the fastening of the monitor in the range of -4° to +21°. The stand is combined with the base through the hinge that allows it to be rotated by 45°.

The sticker on the back of the monitor provides the information about the date and place of manufacturing, serial number, revision, and other useful information.

External display interfaces are presented by two panes: one is on the left edge of the monitor, the other - at the bottom of the rear wall.

Dell UltraSharp U3014

 

The sidebar features two USB 3.0 ports and a card reader designed to work with flash cards of the following types: MS / HSMD / MSPRO, SD / Mini-SD, MMC.

Dell UltraSharp U3014

 

The rear panel offers the following connectors (left to right): power supply connector to an audio device such as Dell Soundbar (if it is connected to the monitor), power connector, input DisplayPort, input Mini DisplayPort, DVI-D, HDMI, output DisplayPort (to connect the second monitor through MST), 3.5 mm audio jack, port USB 3.0 (for PC connection), two ports USB 3.0 (for connecting peripherals).

It is important to explain that the technology MST allows to connect a second display via output DisplayPort directly without using connectors card or motherboard. It is possible to organize a chain of series-connected models, but they must also have similar output ports DisplayPort 1.2.

If desired, the Dell UltraSharp U3014 can be placed on the wall using a VESA-compliant connector 100 x 100 mm.

Display menu and operational demonstration of proprietary technologies

Run and control of menu is realized by using touch keys to changeable functions in the lower right corner of the frame. Also there is a mechanical button of activation / desactivation. Here you won’t fine icons, describing the functions of each button. Instead, next to each of them there is an icon indicating the action of a particular button.

The lowest button runs the quick menu that allows to choose one of the preset picture modes, set the brightness and contrast settings or select the input source.

Also here you can go to the list of basic settings by clicking the appropriate button.

Dell UltraSharp U3014

 

The first two sections contain the brightness and contrast settings.

"Color Settings" are responsible for the choice of color format (RGB or YPbPr), gamma (PC - 2.2, or MAC - 1.8), image mode, as well as reset to factory settings.

Dell UltraSharp U3014

 

The section "Picture parameters" contains the activation function of pictures sharpness, digital noise reduction, dynamic contrast and technology to compensate the illumination irregularity (the latter has two modes of operation), as well as setting the aspect ratio. In addition, there is an option to enable support for DisplayPort 1.2 and use some intellectual improver of video (detects the presence of video in any window on the screen and improves it), which can operate in two modes. Also this section contains information about the parameters of the display and reset button.

"Other settings" provide an opportunity to change the language localization, the degree of transparency of the menu, its location on the screen and timeout. There is the possibility of activation of audio indication of keys pressing and power-saving mode, disable DDC / CI interface and automatic image rotation into portrait mode. If desired, this menu can be checked for the presence of dead pixels or reset all settings to the initial state.

Shortcut button configuration is carried out in the "Personalization" section. You can even set the exact parameters, such as go to a specific preset mode by double-clicking a button.

Testing

Dell UltraSharp U3014

 

While testing the hardware platform of the model Dell UltraSharp U3014 was a mini-computer ZOTAC ZBOX nano ID65 PLUS. Full description of the monitor methodology of research you can read the relevant material.

The Dell UltraSharp U3014 contains eight modes: "Standard", "Multimedia", "Movie", "Game", "Paper", "Color temperature", "Color Space" and "Custom color". First of all let’s look at the figures in the table obtained during testing, and then analyze them in detail.

The maximum brightness level was 290 cd/m2, which is slightly lower the claimed 350 cd/m2, but this is not a disadvantage because it is enough for normal lighting brightness level. Values of 150 - 200 cd/m2, especially in profile designed for continuous operation with the text would be enough. Static contrast also does not reach the promised 1000:1. It reaches a maximum 870:1 in case of activated profile "Standard color". In most other modes it is lower, at the level of 770:1. In some cases, profiles "Multimedia" and "Movie" static contrast ratio falls up to 652:1 and 472:1 respectively. Not the best figures for the modes focused on high-quality video playback.

Model Dell UltraSharp U3014 has a fairly high level of energy consumption; however, it is quite acceptable for monitors with 30-inch diagonal.

Now let’s look at the test results of color.

Due to the preset 14-bit LUT the monitor Dell UltraSharp U3014 has two modes of emulation for Color Space sRGB and Adobe RGB. Hardware calibration using special proprietary software provides several modes. It would seem that the emulation system works fine, but not all is at high level. Color accuracy is certainly good, but there are some complaints. In the field of purple, pink and green hues there are problems. In case of manual adjustment you can solve some of these problems without much effort.

Were obtained excellent results when measuring color accuracy in the modes of "Color Space sRGB», «Color Space AdobeRGB», “Custom color”, "Standard" and even "Paper". In other profiles, especially the "Movie", "Game" and "Multimedia" we observed significant deviations in color accuracy.

Each of the profiles has deviations of red and blue colors, while the curve of green shades remains within acceptable values. In some profiles, such as "Movie" and "Paper" the discrepancy is justified by mode orientation. The "Movie" has overstated blue and understated red component that should improve skin tones and background. "Paper" is trying to make the colors warmer and more pleasing to the eye (although it would be desirable to reduce the blue component of the entire scale). In general, the graph of RGB levels gives the impression of some incompleteness of the factory setting.

In most cases, the gamma curves were slightly understated. Closest to the reference value of 2.2 were profiles "Game", "Color temperature" and both "Color space". At first glance the profile "Standard" doesn’t much different from them, but it is clear that the curves are irregular, which can lead to appearance of spurious tones.

In our opinion the most optimal profile is "Custom color". And we decided to use it to test additional features of the monitor Dell UltraSharp U3014.

Dell UltraSharp U3014

Brightness range was from 45 to 350 cd/m2. The upper limit of brightness of white point is fully consistent with the manufacturer claims. It is perfect for use even in a brightly lit room. The lower mark will provide a minimum load on the eyes in the dark.

Contrast showed stability, varying in the range from 723:1 to 769:1. Of course, these figures are lower than the declared value of 1000:1, however, significant problems with the picture will not be observed.
