Monitor Dell UltraSharp UP2414Q: review and testing

The monitor Dell UltraSharp UP2414Q with resolution Ultra HD, i.e. 3840 x 2160 pixels has a diagonal of 23.8 inches. Thus, it is markedly smaller than other similar solutions on the market. This combination of resolution and size is perfect for users who use sized monitors.

 

Dell UltraSharp UP2414Q

But not only ordinary users should pay attention to the Dell UltraSharp UP2414Q. The applied IPS-matrix with extended color gamut of space sRGB and Adobe RGB, as well as high sharpness of images with no visible pixel lattice is clearly designed for professionals working in the field of graphics and computer animation. However, the main focus of this device is made to their needs, as the used matrix losing to competitors with panels with TN-technology in terms of response time. If you are interested in color accuracy and clarity of the picture, you should become closer familiar with the solution Dell UltraSharp UP2414Q.

Packaging and content 

Dell UltraSharp UP2414Q Dell UltraSharp UP2414Q

Dell UltraSharp UP2414Q comes in a cardboard which provides protection against mechanical damage. In addition to the image of the monitor, it is marked by the model name in different languages and set of icons to illustrate the main features of the product. The most important are: monitor size (23.8 inches), the maximum resolution (3840 x 2160), wide viewing angles (178°), the coverage of the sRGB color at a level of 100% and 99% of Adobe RGB. 

Plastic handle of the box is absent, but instead there are two conventional notches on the sides.

 

 

Dell UltraSharp UP2414Q

 

Supplied set of Dell UltraSharp UP2414Q includes the following components:

  • the power cord;
  • cover of the interface panel;
  • adapter Mini Display Port - Display Port;
  • USB cable for PC connection;
  • CD with drivers and documentation;
  • Quick Start Guide;
  • report on factory calibration of the mode sRGB, color and uniformity of the screen;
  • warranty information.

In the factory report specifies that each monitor is calibrated in mode sRGB using professional measuring systems. As a result of this procedure, the error of color and tint of gray ΔЕ does not exceed 2 units.

For completeness we did not have cable to connect to HDMI interface. On the other hand, is HDMI-cable really necessary, because in case of its connection the vertical refresh rate is limited by 30 Hz, and at the same time DisplayPort provides the value of of 60 Hz? So before buying this monitor you should ensure that your system will be able to fully realize the potential.

Design and operation conditions 

Dell UltraSharp UP2414Q

Design Dell UltraSharp UP2414Q is quite typical in the line of branded devices.

After removing it from the box, it appears unassembled and you need to attach the stand. This can be done by pressing a button. 

Dell UltraSharp UP2414Q

In the attaching place of the stand to the monitor there is a label with icons indicating that the monitor corresponds to various standards and norms. Also here you can learn about the manufacturer of the monitor. It is Wistron Corporation a contractor of Dell.

Dell UltraSharp UP2414Q

Through the use of LED backlighting the manufacturer could avoid excessive thickening of the monitor. But the weight of the device still remains impressive, mainly because of the heavy aluminum stand and complex internal electronic platform. Externally stand looks pretty simple and quite appropriate for a total restraint of Dell UltraSharp UP2414Q. Its matte finish and strong design without sharp corners gives the monitor a rather expensive look.

Dell UltraSharp UP2414Q

Frame bordering is also aluminum. It is worth noting that aluminum is pretty soft metal, so you should take care during transportation of the device.

The case of Dell UltraSharp UP2414Q is completely matte. Every component is fixed tightly and securely.

 

Dell UltraSharp UP2414Q

Height of display is adjustable by 130 mm, and the inclination angle can be changed within 15°. Also rotation by 45° in the horizontal plane (Swivel) and 90 ° in the vertical (Pivot) is provided. At the same time the on-screen menu has an option to automatically rotate the image. All pirouettes are performed accurately and comfortably thanks to a sufficient level of resistance in the joints. But it is provided in case if all six rubber legs that are used to grip the surface of the stand will cope with the task.

Anti-reflective coating copes with its tasks without causing loss of image sharpness.

Despite not being the smallest thickness among monitors (56 mm), the new product can be easily mounted to the wall. This can be done using a standard VESA 100 x 100 mm. First you need to remove the four screws on the mounting space, which can be used for mounting the bracket.

In the bottom of the monitor you can find other external interfaces: power connector, 4 USB 3.0ports, Display Port and Mini Display Port, as well as a digital HDMI.

Display menu and operational demonstration of proprietary technologies

Dell UltraSharp UP2414Q

Dell UltraSharp UP2414Q has sufficiently extensive and functional on-screen menu with numerous options for calibration. To control them are five touch buttons at the bottom right of the monitor. There's also a physical button is placed on and off.

It should be noted that the sensor works quite accurately, but requires compliance with pauses between keystrokes for correct processing of each action. Sometimes it tightens the menu operation.

Dell UltraSharp UP2414Q

The function of control buttons can be changed, but not to be confused before each icon displays the further action.

By default the pressing of the lower button causes shortcut menu with the most frequently used functions.

Here you can set the brightness/contrast, select one of the preset modes or identify the source of the video.

In the first section of the main menu you can set the brightness and contrast settings. The brightness of the influences more to the display backlight than the black color depth level. The index of this parameter varies from 0 to 100, which corresponds to the brightness from 38 cd/m² to maximum.

Dell UltraSharp UP2414Q

The section "Input Source" provides the desired video interface.

Dell UltraSharp UP2414Q

The list of ready modes includes the following items:

  • “Standard” is the default mode.
  • “Multimedia” is available only for HDMI with CEA sync. It is for optimized for multimedia applications.
  • “Movie” is available only for HDMI with CEA sync. It is optimized for video playback.
  • “Game” is optimized for gaming applications.
  • “Paper” is applied to the input signal of format RGB. The brightness and contrast parameters are configured specifically for a comfortable long work with the text.
  • “Color Temperature” allows you to set the screen color warmer or colder.
  • “Color Space” - you can select one of the following options: Adobe RGB, sRGB, CAL1, CAL2. The manufacturer declares 99% coverage of the palette Adobe RGB and a 100% overlap of space sRGB. Modes “СAL1” and “СAL2” are calibrated using approved programs.
  • “Normal color” allows you to manually adjust the color settings.
    • “Gain” is used to adjust the gain of the input signal RGB (by default it is 100).
    • “Shift” is used to adjust the black level shift in RGB format to control the main color of display (by default it is 50).
    • “Tint” is designed to selectively adjust the hue RGBCMY (by default it is 50).
    • “Saturation” is used to selectively adjust the saturation of RGBCMY (by default it is 50).

Dell UltraSharp UP2414Q

The section "Color Settings" contains color rendering control options. Among other things, they include the parameter "input color format." If the monitor is connected to a PC, you need to select RGB, and if to the player that supports only YPbPr you must select it.

Dell UltraSharp UP2414Q

The section "Display options" includes settings of the aspect ratio (4:3, Auto, 16:9 and 1:1). In the latter mode the image is not scaled so the resolutions below the native value appear in the window. Also there is a function of "Color Aligning." It is available only in several modes including "Normal color" and "Standard". This feature works with the internal conversion table: when it is active the indicator of lighting uniformity is improved but at the same time the contrast ratio is decreased.

The function РВР allows you to display images simultaneously from two sources.

Dell UltraSharp UP2414Q

"Energy saving setting" allow you to specify the working conditions of the LED and USB-port.

Dell UltraSharp UP2414Q

"Other Settings" provide access to the following menu items: "Enabling/Disabling of DDC/CI-interface"and "Auto-rotation of the images."

The access the service menu can be obtained by simultaneously clamping the second and fourth top-touch button. It has a lot of information and functions that do not require the changing.

Testing 

Dell UltraSharp UP2414Q

During testing the model Dell UltraSharp UP2414Q the hardware platform was mini-computer ZOTAC ZBOX nano ID65 PLUS. Full description of the methodology of monitor testing can be found the relevant material.

Dell UltraSharp UP2414Q has seven modes: "Standard", "Multimedia", "Movie", "Game", "Paper", "Color temp" and "Custom Color”.  We did not test modes "Multimedia" and "Movie", because these settings are applied only to the HDMI input with synchronization CEA (color palette YUV). Another untested mode was “Calibrated” (in the menu item "Picture options"). After its activation the test results were worsened. Developers advised to turn off the menu for profiles "Color Space sRGB» and "Color Space Adobe RGB».

First of all let’s look at the performance of the profiles obtained during the testing, and then we will analyze the results on the basis of the graphs.

The measured brightness of the monitor mainly demonstrated lower values in comparison with the stated by the manufacturer of 350 cd/m2. It's not bad, considering that by the default setting of brightness is at the level of 50%, and under normal operating conditions the brightness often reduce even lower. Contrast varied within (730:1 - 904:1), which was close to the claimed 1000:1.

The average value of gamut wasat a decent level, especially in the profiles of "Color Space sRGB» and "Color Space Adobe RGB». It seems that Dell UltraSharp UP2414Q passed a good factory calibration. This can be proved by low deviation of dE * 94 suitable for many profiles indicated in the specification value (<2).
Power consumption is relatively high for the monitor with a diagonal of 23.8 inches. Due tothis fact its upper case part was noticeably heated.

Now let’s look at the color rendering.

CIE-diagram of profile “sRGB color space”

CIE-diagram of all modes are very similar to each other except the profile of "sRGB Color Space”. Shift of most reference points is minor or absent. So we can observe lack of saturation in blue, purple and red colors. In numerical terms this  is 98-99 % of space sRGB. This figure is more than enough for professionals working with graphics and video, to say nothing of the usual watching movies or playing computer games. The result is excellent.

Excellent results were recorded when measuring color accuracy in all modes. The only exception is the profile of "Game".

The presence of only green color on most charts is important: the average deviation of dE*94 (ΔE) is about 1, which is less than the permissible level of 1.5. As for the maximum deviation of dE*94 (ΔE), it exceeds the optimal figure 4 in two profiles: "Game" and "Paper", and for other it remains within the morn. In terms of the mode "Paper" it is clear that strong deviations are concentrated only in the light shades of gray, which, in theory, should reduce eye strain when working with text.

This color accuracy will be envied by many more expensive solutions that claim to be professional.

The profile "Paper" has a noticeable sagging of blue curve, which is quite natural, because it is designed to reduce eye strain and make the basic shades warmer. In the "Color spaces" is sharp rise of the blue component in the dark areas. As for the rest, it can be seen that in most cases the colors do not strongly deviate from the reference line and only the red component periodically drops below the optimal range of ± 10%. In general we can say that the balance of RGB source for the model Dell UltraSharp UP2414Q is well configured.

In the standard setting the accuracy of gamma curves is clearly above average, and in both "Color spaces" it is almost perfect. In general, the rest of the profiles show slightly less accurate, but differences are within their specialization. For example, in the profile "Paper" blue curve intentionally remains longer in the black area providing a warm tone.
