Sven Kloevekorn (fordította Tamás Somogyi), 04/16/2018
Business Kaby Lake Laptop / Notebook Security Windows

Okos üzlet(i). A Dell frissíti a 7000-es széria üzleti subnotebookjait az új Kaby Lake-R CPU-kkal, és a 7390-et emellett SmartCard olvasóval, és egyéb biztonsági funkciókkal is ellátta. Tesztünkből kiderül, hogy a nagyon hosszú üzemidő mellett a kijelző, csatlakozók, valamint beviteli eszközök is megfelelnek-e a szakmai igényeknek.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
35.2 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms rise
↘ 14 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 90 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.9 ms).
       Response Time 50% Grey to 80% Grey
48.8 ms ... rise ↗ and fall ↘ combined↗ 24.8 ms rise
↘ 24 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 81 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41.4 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8895 (minimum: 43 - maximum: 142900) Hz was measured.

Kontra

- nem nyitható egy kézzel, a fedél felemeli az alját
- nincs Thunderbolt 3
- nincs szervizfedél, a telep kívülről nem hozzáférhető
- viszonylag kis billentyűzet
- kissé megbízhatatlan ujjlenyomat olvasó
- a touchpad gombjai nem túl jók
- zajos space billentyű
- nincs PCIe SSD
- rossz, idegesítő hangrendszer

Az új Dell Latitude 7390 majdnem mindenben kitűnően teljesít. A nem túl durva 1400 eurós (~$1732) árú modellel egy kerek egészet kapunk, amelynek alig van hiányossága.

Itt a kicsit kicsi, de amúgy jól sikerült billentyűzetet, a középszerű touchpad gombokat, a Thunderbolt 3 hiányát és a zajos Space gombot kell megemlítenünk. Ennél is kisebb design hiba, hogy a fedél felemeli az alapot, ha olyan 135°-nál nagyobb szögben nyitjuk ki. Amit tényleg nem szerettünk, az a rémes hangrendszer és a gyenge ujjlenyomat olvasó volt.

Nem csak sokkal több elemből áll a "Pro" lista, de fontosabb dolgok is vannak rajta. Még az i5-8350U is egy kicsit túl sok a Latitude-ben irodai feladatokra, de mivel az üzemidő így is remek, egy kis plusz erő soha nem árthat. Az egyszerű, de kiváló minőségű ház, nagyon jó beviteli eszközök, a biztonsági funkciók, átgondolt csatlakozókínálat, kontrasztos kijelző, a Windows 10 Pro és végül de nem utolsósorban a 3 éves jótállás, valamint a csendes működés egyértelműen megérdemlik az ajánlásunkat.
