Samsung C27H711 uses a slim body design, the thinnest body at about 9.9mm, three sides 1.2mm narrow frame design, can help users easily achieve seamless multi-screen docking.

Judging the quality of a monitor is mainly to see how the screen behaves. As the Samsung's first year masterpiece, the C27H711 adopts Quantum Dot technology. The picture color is naturally more vivid and vivid than the ordinary monitor. At the same time, the 2K ultra-high resolution makes the overall picture clearer. Say no more, the following author directly on the map, take a look at this monitor's screen performance what?

Through the above a few real shots can be seen, Samsung C27H711 still maintains the unique color advantages of quantum dot technology, at the same time in the processing of the details of the picture is also very detailed, the reproducibility of the picture color is also very high, in general the picture performance is good . In every big picture, every detail and every color is well presented.

Below we perform the performance measurement part, the test items gamut coverage, color reproduction accuracy, color temperature consistency, color uniformity, brightness uniformity, gamma curve. Numerous test projects allow us to examine the Samsung C27H711 in all aspects. In order to ensure the fairness, objectiveness and repeatability of the test, we need to introduce the test environment and test platform:

Â· Ambient light color temperature: 6500K

Â· Ambient light: 51 Lux

Â·Signal input: HDMI

Â·According to ISO3664 standard

A card test platform configuration list

To test the objective accuracy of the data, as required, we first let the monitor warm up for at least 1 hour, and turn off the color gain function that may affect the test results. In the test, we used the Spyder5 Elite colorimeter to complete the entire process and then produced its original ICC file. (The red spider 5Elite purchased by this test is the latest flagship product, and the color test is more accurate.)

Spyder 5 Elite

â— Gamut coverage test:

Remarks: In the figure below, the green triangle area represents the sRGB color gamut, and the red triangle area represents the color performance of the monitor. When the red triangle area can completely wrap the green triangle area, it indicates that the monitor can fully display all the colors.

Due to the Spyder 5 Elite software testing sRGB link, the software can only display 100% of the value, but in actual test performance, the actual color range of the Samsung C27H711 is much higher than the standard sRGB range. Therefore, Samsung C27H711 this quantum dot display is more excellent in color performance.

100% sRGB and 85% AdobeRGB gamut coverage measured

Result analysis:

In theory, the red area is ideal if it completely covers the green sRGB color space. According to actual test results, the red-side triangle representing the Samsung C27H711 color gamut completely covers the entire sRGB color space. It covers 100% of the sRGB color range (due to Samsung C27H711's quantum dot technology, the color range is high. A lot of sRGB, the actual value is higher than 100%), and covers most of the purple-triangular triangle, the color gamut coverage of Adobe RGB reaches 85%, such a color gamut coverage is very bright in the same professional-grade products Can fully meet the professional needs of professional users such as photography, design, drawing, editing and editing.

People's display needs of liquid crystal can display more abundant colors as much as possible. Another key pain point is to have accurate color reproduction capability, that is, the monitor needs to be able to reflect each color on the display screen. Here we take a look at Samsung C27H711's color reproduction capabilities. The color reproduction accuracy index is expressed in the industry using the Î”E value, and Î”E can quantify the accuracy of color reproduction as a value that accurately reflects the accuracy of the display's color representation.

Note: The Î”E value reflects the difference between the display and the standard value, so the smaller the value, the better. The higher the score, the more distorted the color.

Color reproduction accuracy test results

On the left side of the test result graph, Samsung C27H711 displays the Î”E value of each color. The smaller the value is, the more accurate it is to display the color. For the 48 colors in the test, the average Î”E value is 0.95 and the minimum value is 0.13. In 48 kinds of test colors, the Î”E value of most colors is below 1, and it is natural to have such excellent performance. Quantum dot technology used in this monitor.

Color uniformity test:

In the hue uniformity test, the yellow block represents the difference between the color temperature value and the standard value of the screen in each block of the screen. The larger the value is, the darker the color is, and before we interpret the result of the screen uniformity test of Samsung C27H711 Let's take a look at the metrics.

The uniformity test is divided into two parts: brightness uniformity and chroma uniformity. In the test session, the screen is equally divided into 9 blocks (marked in the figure). The colorimeter will measure the maximum difference between the luminance and chromaticity coordinates of each block at different percentages in the test, thus confirming the degree of uniformity of the display.

Remarks: It is still the smaller the maximum difference, the better, indicating closer to the D65 standard value, otherwise the greater the value, the lower the brightness.

Chroma uniformity test results

We can see that the Samsung C27H711 is very eye-catching in terms of uniformity of color. In the D65 standard, the color temperature value of 6500K indicates that the color is accurate and does not appear cold or warm. Through our tests, we can see that the color temperature in Area 8 is closest to the standard of D65, while the color temperature in Area 1 has a large difference from the standard color temperature value, and the difference value is 4.8. However, overall, Samsung C27H711's color uniformity performance is still good.

Brightness uniformity test:

The screen brightness uniformity test was also tested with the Spyder 5 Elite colorimeter. The screen was divided into 9 large areas. The brightness and the chromaticity coordinates of the screen in each area were tested and the following conclusions were obtained. (The following results are all 100% at the IRE output, which is the result of the test when using maximum brightness and contrast output.)

Brightness uniformity test results

The gray part of the above figure represents the brightness distribution of the Samsung C27H711 screen. The darker the gray, the lower the brightness. If it is white, the brightness is the highest. We can see that the brightest part of Samsung's C27H711 screen is in area No. 2. The biggest difference in brightness is in area No. 9. The difference from the maximum brightness of the screen is 17%. As a whole, the brightness in the upper left area of â€‹â€‹the screen is higher. The bottom right is lower. This brightness distribution is also consistent with the user's usage habits.

Gamma curve test:

Our significance for the Samsung C27H711 curve test is that Gamma (gray scale) is the name of a non-linear operation used for encoding and decoding in video/image if the display's brightness coefficient curve is close to the standard curve (photometric 2.2 ) means that the monitor can properly reset the screen brightness and contrast; if the deviation is greater, it means that the monitor's ability to reset the brightness and contrast is worse.

Gamma curve test

In theory, the red, green, and blue lines are completely coincident, and a pair of straight lines is the most ideal. Samsung C27H711's gamma curve test results are ideal, although some slight separation, but overall it is acceptable. This means that the monitor's reset brightness and contrast are better.

Color temperature consistency test:

Next, the purpose of the color temperature consistency test is to test the stability of the color temperature of the monitor under different brightness. The user may adjust the brightness of the monitor at any time. At this time, the contrast and color temperature should not change too much. We adjusted the brightness of the Samsung C27H711 to 0%, 25%, 50%, 75%, and 100%, respectively, to test the full white screen brightness and the full black screen brightness and chromaticity coordinates, calculate the contrast and color temperature values, and the color temperature under each brightness. The value and contrast ratio should not change too much.

White point color temperature test data

In terms of color temperature consistency, it can be seen that the performance of the Samsung C27H711 is very stable, and the color temperature of the white point has remained at 7600K. However, compared with the standard color temperature, the display product is somewhat cooler than the standard color temperature, but this cold display effect will be More in line with the Chinese people's aesthetic habits.

Each excellent product naturally lacks a lot of user-friendly design, Samsung C27H711 is also true. In the display's setting interface, we can easily see that the interface is simple and clear, there are individual setting modes that can fine-tune various parameters, and there are several preset different types of modes for users to choose.

Eye protection mode off / on before and after contrast

Samsung C27H711 has eye protection mode, users can open this function on their own to achieve high-energy short-wave blue light shielding and filtering. At the same time, it can also ensure that the display screen does not flicker, can effectively avoid flickering staggered light environment, and more effectively protect the user's eyes. This function is a very intimate setting for users facing the screen for a long time.

Samsung C27H711 has FreeSync function

For e-sports players, Samsung C27H711 also provides "welfare" for this group of people. The Samsung C27H711 uses AMD FreeSync technology to synchronize the display refresh rate with the output frequency of the graphics card to better solve image tearing, stuck and delay phenomena during high-quality rendering. Faster response times and dedicated game modes allow players to better experience the game.

The fiery gaming market has attracted a lot of e-sports equipment, which is an indispensable part of the display. Samsung C27H711 not only has an advantage in the color of the screen, but also has a good performance in the game. Next, we will measure the popularity of the two highly popular e-sports games, Watch Pioneer and League of Legends, to see how the Samsung C27H711 has performed in games.
