Test: Dell Latitude 12 5285 2-in-1 (sammanfattning)

Bernhard Pechlaner, 06/13/2017

Deja Vu. Dell Latitude 12 5285 2-in-1 påminner inte så lite om Microsofts populära Surface Pro 4 – från skärmens storlek till dimensionerna överlag och tillbehör som ett löstagbart tangentbord och stylus. Den är snarlik på många områden, men inte alla.

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
30.8 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 12.8 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 (26.6 ms).
       Response Time 50% Grey to 80% Grey
42.4 ms ... rise ↗ and fall ↘ combined↗ 20.4 ms rise
↘ 22 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. » 56 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.5 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 210.1 Hz

The display backlight flickers at 210.1 Hz (Likely utilizing PWM) .

The frequency of 210.1 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8581 (minimum: 43 - maximum: 142900) Hz was measured.

Dells Latitude 12 5285 är en bra 2-i-1-dator för företagsanvändare. Den kombinerar god ergonomi, anständig prestanda och bra uthållighet i ett elegant och tilltalande paket. Visst påminner den mycket om Microsofts Surface Pro 4, men vi förväntar oss inte att Dell ska frångå ett framgångsrikt koncept bara för att bryta normen. 


Det inkluderade tangentbordet Travel Keyboard känns bra och har även tvåstegs bakgrundsbelysning. Active Stylus fungerar mycket bra som en extra inmatningsenhet och kan erbjuda extra funktionalitet som snabbstart av Microsoft OneNote och andra program. 


Dellmaskinen skiljer sig från konkurrensen på några punkter: För det första är skärmupplösningen lägre – vilket inte är något vi ser som en väsentlig nackdel med tanke på Latitudes företagsfokus. Skärmen är även extremt ljusstark. Dessutom är 2-i-1-hårdvaran ganska lätt att komma åt och underhålla, vilket alltid har varit en akilleshäl för formfaktorn.


Saker som vi uppskattar desto mindre är att Latitude 12 5285 blir mycket varm under belastning och att den väger något mer än konkurrenterna. En Thunderbolt 3-port hade heller inte skadat. Datorn råkar också vara riktigt dyr, vilket kan göra alternativ som Asus Transformer 3 Pro eller den vattenkylda Acer Aspire Switch Alpha 12 mer tilltalande – trots deras mycket kortare batteritid. Microsoft Surface Pro 4 är fortfarande ett bra val också, särskilt versionen med Core i5 och 256 GB SSD, som för närvarande säljs för ett konkurrenskraftigt pris.
