Presentation

Dell offers several ranges, for both laptops and all-in-ones; if the Inspiron is positioned as solid and affordable, the high end is represented by the XPS range. Today is the XPS 27 7760 (2018), all-in-one computer whose configuration tested here is launched at more than € 2,500, which arrives in our lab.

Design

Dell does not change a design that wins and therefore takes the chassis of the previous XPS 27. A chassis that convinced us last year and still convinces us today. Irreproachable in its construction, it is adorned with metal and plastic, according to the codes of the XPS range.

The touch screen, supported by a double articulated foot, can be tilted almost flat to be used as a tablet. Note, Dell does not provide a stylus with the PC. In addition, the manufacturer has focused on the sound of the PC through six speakers placed under the screen, which will not necessarily appeal to the followers of sobriety and discretion.

Side connectivity, the XPS 27 7760 (2018) is complete and offers on its edges a USB 3.1 port, an SD card reader, and a 3.5 mm jack. At the rear, it also offers four USB 3.0 ports, an HDMI port, an Ethernet port, a DisplayPort 1.2 port, another port jack, and two Thunderbolt 3 ports.

Dell also provides a keyboard and a mouse. The chiclet keyboard certainly adopts a sober design, but shows its limits to use by offering a long run, but an uncomfortable knock sensation, as well as a finish that would have deserved more attention to our meaning, but it’s here is a question of taste, some members of the editorial appreciating the device. The mouse, she, is content with the bare minimum, caring more about its design than its comfort.

It is during its passage in front of our technical camera that the Dell XPS 27 7760 (2018) reveals its first weaknesses. During our usual protocol (benchmark of Metro: Last Light for 1 hour), it reaches the temperature of 52 ° C on its top grid. A little surprising heating, but still high, especially since it is not offset by silent ventilation. When put to the test, the PC emits an unpleasant sound, which rises to 46 dB.

As you might expect, the Dell XPS 27 7760 (2018) consumes a lot. On the desktop, it needs an average of 51 W and up to 210 W in play. In standby, it consumes nothing. High numbers, but expected on this type of computer.

Overall, the Dell XPS 27 7760 (2018) is therefore a good product with some construction weaknesses. If its design is impeccable, the engineering would have deserved a little more care for a less pronounced heating or a noise more discreet. Nevertheless, he finished very well.

Screen

The screen of the previous model of the XPS 27 was his big highlight. Unfortunately, for this new version, Dell has rested on its laurels and delivers a much less convincing slab. The PC is equipped with a 27-inch (68.6 cm) touch-sensitive IPS display, with a definition of 3840 x 2160 px (Ultra HD, so), with 75.51% screen / facia ratio only. A score that may surprise on the part of Dell, yet customary screens edge to edge. This is far from the case of the Dell XPS 27 (2018), even if its edges are unobtrusive, and the space dedicated to the loudspeakers even more the ratio.

In the laboratory, the Dell XPS 27 7760 (2018) delivers half-tone results, even disappointing. The elevated temperature of 7,825 K has a blue screen, far from the ideal balance of 6,500 K. The contrast ratio is also a bit low at 1,065: 1. The maximum brightness, set at 383 cd / m², remains good.

But it is especially the calibration of the colors which poses problem on the screen of the Dell XPS 27 7760 (2018). The average delta E (difference between the actual colors and the colors displayed, considered excellent below 3) is here at 4.8. In fact, it’s not a bad score. But by looking at the detailed results, we realize that the respect of colors is not the party: the set of greens, including cyan, are anything but faithful, and the colors containing red or magenta are not exemplary. Only the gamma curve, of great stability, is almost irreproachable, a sign of a good gradient of gray.

It should also be noted that Dell offers, through an integrated tool, to simply change the calibration of the screen (sRGB, Vivid Colors, Adobe RGB). If the temperature can change as well as the contrast (the measurements that we present here were obtained with the sRGB profile, which gives the best results), the respect of the colors remains unsatisfactory on all the profiles. A major handicap for those looking to do photo editing, for example.

Finally, note that the remanence is 13 ms, which is good on this type of slab.

Graphics

The Dell XPS 27 7760 (2018) is equipped with a modest AMD Radeon RX 570 graphics card. What to play occasionally, but no more.

During our usual tests (definition in 1080p, maximum graphics, vertical synchronization disabled), the PC knew to defend itself, without shining. The PC showed its strengths only with Metro: Last Light, since the game averaged 93 fps. But The Witcher 3 averaged 32 fps; as for Star Wars Battlefront II and Assassin’s Creed Origins, they shot at 45 fps, while Civilization VI reached 57 fps. With such results, you can not imagine playing with full use of the all-in-one Ultra HD display while maintaining good fluidity. The Dell XPS 27 7760 (2018) will be enough for casual gamers, but it’s clearly not a gaming PC.

Conlusion

With this Dell XPS 27 7760 (2018), Dell wants to deliver excellence. Nevertheless, the builder fails on crucial points. It delivers for example a disappointing screen, which would have deserved much more care, and has poorly controlled heat release from his PC. Defects all the more ragging that they did not exist on the previous model. In the end, the Dell XPS 27 7760 (2018) is an all-in-one that is correct, which remains insufficient for a computer sold more than 2500 €.
