Dell Latitude 15 3588 Wireless Driver

The laptop uses a familiar panel: AUO B156HTN03.8 (AUO38ED), also used in the HP EliteBook 850 G4. This is a TN panel with a resolution of 15.6 inches diagonally and a Full HD resolution (1920 × 1080). The pixel density is 142 dpi, while the pixel pitch is 0.18 x 0.18 mm. The screen can be considered “retina” when viewed at a distance equal to or greater than 60 cm. However, there are some small differences between this and the EliteBook.

The maximum brightness registered is 242 cd / m2 in the center of the screen and 239 cd / m2 averaged over the whole area with a difference of only 11%. With maximum brightness, the color temperature on the white screen is 6980K, which is a bit cooler than the optimal 6500K temperature. Unfortunately, things change as we move towards grayscale, where the average white point is 12,000,000, but our profiles are interested. You can also see how the values ​​change to 140 cd / m2 (55% brightness). Without calibration, the dark gray color will appear in dark blue.

To make sure we’re on the same page, we’d like to introduce you to a small introduction to the sRGB and Adobe RGB color gamut. To begin with, the uniform CIE chromaticity chart of 1976 represents the visible spectrum of colors for the human eye, which gives a better sense of coverage and precision of the range of colors.

In the black triangle, you will see the standard color gamut (sRGB) used by millions of people in HDTV and on the Web. As for Adobe RGB, it is used in professional cameras, monitors, etc. to print Everyone uses the colors of the black triangle. This is the essential part of the quality and color accuracy of a classic laptop.

However, we have included other color spaces, such as the famous DCI-P3 standard used by film studios, as well as the Rec.2020 digital UHD standard. However, Rec.2020 is still part of the future and it is difficult for today’s screens to cover this correctly. We have also included the so-called Michael Pointer range, or pointer range, which represents the colors that naturally occur around us each day.

And as expected, the laptop barely covers half of the sRGB color gamut. So do not expect good multimedia performance.

The installation of our Health-Guard profile not only eliminates PWM, it also reduces harmful emissions of blue light while preserving the color accuracy of the screen. If you are not familiar with blue light, the TL version; DR is a program that negatively affects your eyes, your skin and your entire body. You can find more information about this in our article on Blue Light.

While we did not expect the best possible IPS solution on this laptop, but as the configurations increase with the price, the quality of the TN panel is simply unacceptable. Only half of the sRGB resolution is covered, the contrast ratio is very low, the color accuracy is really bad and the white point is completely out of balance. The good thing is that our custom profiles can solve some problems by improving the color accuracy and adjusting the white point. We are also pleased to see a straight line in our PWM detection equipment, which means that the screen does not blink and that it is OK to use it for long periods of time.
