Notebook check will get one unit soon and I am sure they will provide an unbiased review!
Funny you should say that, because here it is:
And what do they say [slightly corrected google translate]…
The 3K display from Sharp offers a resolution of 2,880 x 1,920 pixels, which corresponds to a pixel density of 281 ppi for a visible area of 12.3 inches. The touch display is equipped with Corning Gorilla Glass 4, which guarantees a very high scratch resistance. In order to counteract the reflections on the smooth glass surface, the display of the Dell Latitude 7285 is provided with a reflection-free coating. In addition, the anti-lubrication coating ensures that residues are easier to remove from the surface.
Within the scope of our measurements, the Sharp Panel achieved an average brightness of very good 490 cd / m². Here only the Dell Latitude 12 5285 with 522 cd / m² can keep up. The Dell Latitude 7285 loses with a brightness distribution at only 86% [same comment as other review]. This is where the Lenovo ThinkPad X1 yoga leads with 95%. For brightness control, the Dell Latitude 7285 uses PWM, which we measured with a display brightness of 20% with 922 Hz. Also at the edges shows with a completely black representation some “Clouding”, which is however not overly strongly pronounced. [see picture]
The display quality is very high. Color representations are very well reproduced and do not look washed out. In the delivery state, the average DeltaE-2000 deviations of the grayscale and the colors compared to the sRGB color space are only slightly increased (3.5 and 4.7, respectively). A calibration of the display could significantly improve these values (1.0 or 1.2). The Farbräume can be covered to a large extent. With sRGB color space the Dell Latitude 7285 almost reaches 100% with a color space of 99.8%. The extended AdobeRGB color space is at 67%. In the test comparison, only the Lenovo ThinkPad X1 yoga, with its OLED panel, has a higher color space pecentage. Thus, the Dell Latitude 7285 can also be considered for (semi-) professional use.
Despite the antireflective layer, the glass surface can not avoid all reflections. But at least they can be minimized. For outdoor use, the Dell Latitude 7285 is nevertheless suitable, because the high display brightness can ensure even in the sunshine for good readability on the screen. However, since reflections can not be completely avoided, we still recommend users to prefer a shadow place.
At our angle of view, the screen behaves IPS-typical. All representations can be recognized very well from all nine viewing angles. Even with the four corner images, there are hardly any weaknesses which, despite IPS, are often covered with a light gray cloth.
So, all very positive, brighter than the spec, with the only slight downsides being the brightness distribution and some clouding (backlight bleed) around the edges (shown in the link), which might just be a manufacturing defect with that unit. One on the positive points listed for the laptop is the “very good 3K touch display with high color space coverage”.
