Mention dell this brand, most consumers will think of two words – high-end, professional. Because in dell family, high-end became the generation of product line words, not only has the exquisite products work, and the user’s reputation as a necessary condition of the run. And high-end monitor is the most representative products, the launch of the 27 inches high scores screen than other brands of products, can let high-end users have more choice space. In the face of each big brand was launched the 2560 * 1440 resolution wide Angle products, dell in 2012 in the fourth quarter, forward again, a lot of new products, before we bring the U series of 2713 hm, this product is doing very well, but it did not reach the standard of wide color gamut, so it’s not U2713H and the counter, but they still have a lot of similar place, then, we’ll pass the test, to let everybody to dell U2713H wide color gamut monitor understand somewhat.
Dell U2713H is a section 27 inches, the IPS panel of wide Angle monitor, but in the resolution on it also beyond the 1920 * 1080, 2560 * 1440 promoted the height, the user view of the picture is more clear, because this product has wide color gamut, color depth can reach 1.07 billion color, so can realize smooth color gradient and clear sharp details. In configuration, also has 2 million: 1 dynamic contrast, 6 ms response time, 350 CD / ㎡ brightness and so on selling points. In the interface, dell U2713H equipped with D – Sub, DVI – D, HDMI, monitorport, 5 × USB 3.0 and the brand other high-end machine did not common to the Mini monitorport interface, can completely meet the needs of users.

Dell U2713H monitor as a result of the 2560 x 1440 high resolution, so in the picture will show more clearly, then, high resolution and 1920 * 1080 resolution exactly how much difference? Next we will for you to compare.
First of all, we use the Spyder Elite 4 color correction instrument to test dell U2713H color performance characteristics. If the traditional way of the pictures were taken, due to the digital camera imaging differences and consumer use of monitor differences, can’t actually see the original monitor picture of the best effect. Therefore, we use a professional test equipment testing, output can can learn about the actual monitor of the ability of graphics and more conducive to users understand this kind of monitor the true level. For the test, we completely according to the standard test flow test.

Next, we have to do is to use a Spyder Elite 4 color correction instrument to produce this kind of type of original ICC document, and the analysis U2713H dell color characteristic performance. We provide you with the four groups of color forms, let everybody on the color space are fully understand. In the picture below white closed curve on behalf of the sRGB color space, red closed curve on behalf of dell U2713H color space.
Theoretically speaking, the red areas completely covered the white area is the most ideal results, indicating that the monitor output colour is reliable, and from above we can see that U2713H dell in conventional color performance reached the best level, and cover the sRGB color space was 90% above, and we will adjust to the wide color gamut, colour performance more rich, reached the level of outstanding. In addition, it can support more than 99% AdobeRGB color space, the overall performance also reached the high-end IPS monitor level.
Dell U2713H for most color reduction of performance is very good, especially for 6 b color processing, reached 0.20, this in the same specification product is very rare. And other Δ E value were also good, this also for professional users with a more excellent picture.

Next to dell U2713H screen uniformity testing. Screen brightness uniformity test with the same Spyder Elite 4 color correction instrument testing, we will screen is divided into nine large area, respectively test calculation the screen in each area different percentage of the brightness and chromaticity coordinates, and finally draw the following conclusion. (the results in the IRE output 100%, namely use maximum output brightness and contrast test results)
Through the above, we can see the central place U2713H dell screen brightness is the highest, numerical for 209.1 d/m2. And in the top right-hand corner of the screen, we see the brightness is the lowest, and the screen brightness difference reached 20%, but the product of the average brightness difference for 12% to medium to high level. But dell’s high-end machine in the central position of the screen brightness always is the highest.
Color uniformity project is this year we launched new projects, and through the Spyder Elite 4 color correction instrument to dell U2713H screen in different areas of the color temperature test, and compare with standard D65, calculate the current screen block color temperature and standard color temperature difference, summary become color uniformity and draw the following conclusion. (the results in the IRE output 100%, namely use maximum output brightness and contrast test)
In the standard D65, color temperature value for 6500 k said color is accurate, won’t appear slants cold or slant warm. And we see dell U2713H on the far right of the screen the central position of the color temperature and D65 standard consistent, but the top left corner of the screen color temperature and standard value differences. But comprehensive speaking, this product colour temperature performance or reached the medium to high level, in the same specification products is also very good.

But comprehensive speaking, this product colour temperature performance or reached the medium to high level, in the same specification products is also very good.
Next, we color temperature consistency test. The purpose of this test is the test monitor products in different brightness white spot color temperature stability, after all, the user can adjust the monitor brightness, contrast and color temperature at this time should not have happened too big change. We will U2713H dell respectively the screen brightness adjustment to 0%, 25%, 50%, 75% and 100%, test all white screen brightness and all the black screen brightness and chromaticity coordinates, and calculates the contrast and color temperature value. Each brightness color temperature value and contrast ratio does not change is the most ideal.
In the color temperature uniformity, dell U2713H performance is relatively stable, keep to 6400 k to 6500 k, and the standard difference is small, so, this product in all the luminance values change represented by the colour slants warm, performed at the upper level, and can play for professional users to provide more comfortable image (reference value for 6500 k, the actual value less than 6500 k).
