Sebastian Bade (fordította Tamás Somogyi), 09/12/2017
Business Convertible / 2-in-1 Kaby Lake Windows Tablet

Megbízható útitárs! A Dell egy sokoldalú 12 inches átalakíthatót mutatott be, időtlenül szerény és elegáns designnal. Egy nagyon takarékos Intel CPU hajtja. Az, hogy emiatt hosszú üzemidőt kapunk-e, és hogy emellett mennyire teljesít jól a Dell Latitude 7285, cikkünkből kiderül.

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
30.4 ms ... rise ↗ and fall ↘ combined↗ 15.6 ms rise
↘ 14.8 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. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.7 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 19.6 ms rise
↘ 24.4 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. » 63 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.8 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 detected 922.1 Hz20 % brightness setting

The display backlight flickers at 922.1 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 922.1 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.

The Dell Latitude 7285, provided by Dell Germany

A Dell Latitude 7285 egy kiváló minőségű átalakítható gép, modern alkatrészekkel. Az Intel Core i5-7Y57 stabil teljesítményt nyújt, amely elegendő a mindennapi irodai feladatokra, de multimédia alkalmazásokhoz is. A takarékos processzor általában könnyedén lépést tud tartani a gyorsabb ULV procikkal is. 2300 eurós (~$2740) árával a tesztpéldány nem éppen olcsó. A vásárlók ezért azonban egy hibátlanul összerakott, minden téren remek minőséget tükröző készüléket kapnak.

Az ár elsőre ijesztőnek tűnhet, de a Dell egy nagyon jól összerakott gépet kínál egy első osztályú, 3K kijelzővel, és egy sor modern csatlakozóval. A tableten kívül pedig még egy billentyűzet dokkolót, egy Dell Active Pen-t és 36 hónap garanciát is kapunk.

A jó anyaghasználat és a visszafogott design szimpatikus. A Dell Latitude 7285 kijelzője is nagyon jó pontszámot kapott, mivel fényereje és színlefedettsége is kiváló. A processzortól kisebb teljesítményt vártunk, de mivel a Dell nem a szokványos 4.5 wattos TDP-re korlátozta, ezért felülmúlta a várakozásunkat. Az összes teszt eredménye azt mutatta, hogy a Dell Latitude 7285 az Intel Core i5-7Y57-tel, lépést tud tartani a versenytársakkal.

A készülék fogyasztása miatt azonban kissé csalódottak vagyunk, mivel a takarékos alkotóelemek miatt sokkal jobbra számítottunk. Ez az üzemidőre is kihatott, és csak a második telep jelenléte mentette meg a készüléket attól, hogy nagyon rossz pontszámot kapjon ezen a téren.

Ez az eredeti értékelés rövidített változata. A teljes, angol nyelvű cikk itt olvasható.
