Samsung S27D390H monitor: review and testing

Samsung is among the top five of the world's manufacturers of monitors. Therefore, testing the data display, we simply could not ignore its products. Its lineup strikes by its variety: there are about 40 different names of the PC monitors. Familiarity with them we decided to start from the 27-inch solutions Samsung S27D390H, built on the basis of a matrix PLS the head of which is Samsung.

Design and usage properties

Samsung S27D390H

We have already noted that the design of monitors is always under the care attention. Model Samsung S27D390H is a great proof of that. Looking at its design we thing about "amazing", "excellent" and "elegant" words. Slim case with narrow frame visually increases the screen size (27") and the narrow translucent leg creates the impression that the monitor is over the surface of the table. The glossy panels and bezel made of transparent aqua plastic is a proprietary design feature Touch of Color (ToC). On the background of most competitive solutions, the model Samsung S27D390H looks very impressive and easy to fit into any room or office.

The power supply unit is outside the monitor so it has a relatively small case thickness (80 mm) and small weight (4.7 kg). The rear panel has no wall mounting so the model Samsung S27D390H can be placed only on the desk.

The leg also has the general style of the monitor - the same elegant and graceful. Its main part is made of a translucent material (such as hard plastic) of aqua color. Good firmness, of the monitor is provided by a broad base covered by glossy panel. In principle, the design is reliable, however, the use of thin legs still made some adjustments. So, pushing or hitting the table can lead to a swinging of small vertical monitor.

As for the functionality of the leg, it is small traditionally for the 27-inch solutions. In these screen sizes, many manufacturers primarily focused on reliability. In this case, the user can adjust only the inclination angle of the display between -1° ... +20°.

Video connectors are represented by analog D-Sub and HDMI digital ports. In both cases, there is a support of resolution 1920 x 1080 at a refresh rate of 60 Hz. Also note the audio output for headphones, and the connector to the computer's sound card is missed. That is, the sound is transmitted via HDMI interface. Recall that a D-Sub video connector does not support this capability. Built-in speakers and other multimedia options are not provided. While many users will find it as an advantage because they do not need to overpay for unclaimed functionality.

Buttons to control the display and navigation are located in the lower right corner of the case and are touch sensitive. Each of them is equipped with a small explanatory inscription, which is easy to read even in the dark. In addition, during the setup of the monitor the bottom of the screen always displays a hint in the form of icons. So you won’t lose in menu.

Display menu and operational demonstration of proprietary technologies

The menu has a fairly simple structure: the left side shows a list of tabs, and the right - their contents. The main sections are "Image" and "Color". Here are the settings responsible for brightness, contrast and gamma of the image. Also there is the possibility of manual balancing of key colors (red, green, and blue).

Another positive side of the screen menu is the presence of small explanations that appear when you select an item. Selection of preset profiles is performed on the section "Image" in subsection «Samsung Magic Bright». The mode "Game" also can be activated via a special button on the face of the monitor.

To control the technology Samsung Magic Upscale is possible via a certain menu item. This function in hardware increases the sharpness of the image. Following are photos of image patch on the screen by using different values of the parameter «Samsung Magic Upscale».

We have to admit that the technology works quite well and can be useful in different circumstances, such as when reading text from scanned pages and photos or while zooming the images with low definition. However, in games or applications that use 3D-graphics, the activation of this feature can cause artifacts when displaying thin lines and boundaries of objects. Therefore, to get involved in technology Samsung Magic Upscale still not worth it, and apply it only in those cases where it really helps to improve the image quality.

The monitor has five recorded modes: "Custom", "Standard", "Dynamic Contrast", "Cinema", and "Game". First of all let’s look at the performance of profiles obtained during the test, and then analyze the results on the basis of the graphs.

Black area brightness, cd/m2

With the exception of mode "Standard", in all cases the brightness was at the level 311 - 313 cd/m2, which is consistent with the claimed index of 300 cd/m2. Lovers of bright pictures should like it, but for the daily work in normal lighting this parameter can be reduced to 150 - 200 cd/m2, or use the aforementioned profile "Standard". As for the static contrast ratio, it also has a very high level 940:1. Thanks to this picture on the screen will have juicy and vibrant colors. Also the rate monitor power consumption is good. Depending on the selected profile it ranges within 16 - 27 W. These values are more characteristic for the 24-inch monitors than for the 27-inch options.
Note that there is no mode for reading of the text from the screen (with a lower brightness and contrast). Therefore, if necessary the appropriate settings have to be set manually.

Now let's learn the color rendering.

Color gamut of sRGB ranges from 89.7% to 91.8%. For everyday work such indicators would be sufficient. If we analyze the nature of the color gamut, in all cases there is approximately the same pattern: the lack of turquoise, blue and pink shades, and oversaturation in light green and yellow-orange areas.

During measuring of the color accuracy were recorded the excellent results. The average deviation dE*94 (ΔE) shades from the standards in the modes "Custom", "Standard" and "Contrast" are in the range 0.38 - 0.41 with an acceptable value of 1.5. The maximum values were also quite low (the green color on the charts). Thus, Samsung S27D390H is perfect for entertainment purposes as well as for the graphics processing. However, it won’t replace the professional monitor due to incomplete coverage of the color palette of sRGB.

In the other two profiles color accuracy is not so good. In our opinion, this is due to the desire to emphasize or mute certain colors.

In most cases the balance of RGB in the preset profiles is good: curves of the three primary colors are close to reference line 100% (range 95% - 110%). The only exception is mode "Cinema". It traditionally has overestimated blue component to give the picture more cold aspect.

The setting of gamma range in profile "Dynamic contrast" is perfect. The situation is slightly worse in modes "Custom" and "Standard". Here is a slight deviation of gamma curves from the reference line. However, a large coefficient of static contrast hides this disadvantage.

But in the profiles of the "Cinema" and "Game" gamma setting is far from ideal, although we propose that this is done intentionally. In these cases, the detail in the shadows will be lost, making the picture more intense and dynamic scenes more "alive". The last will be especially important in racing simulators, as it will allow to dive into the atmosphere of the game. But during watching movies such effect would prevent the perception of the action.
