Display Response Times

ℹ
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
27 ms ... rise ↗ and fall ↘ combined↗ 7 ms rise
↘ 20 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 64 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
   ↔    Response Time 50% Grey to 80% Grey
48 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 33 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (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 (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ
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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured.

In review: Dell Latitude E7470. Test model courtesy of Dell Germany

En mer utförlig version av testet finns på engelska här.

Dell håller fast vid sin filosofi att inte avvara någon funktionalitet i den senaste av företagets Ultrabooks. 14-tumsdatorn är välbyggd och kraftfull nog för alla vanliga företagsprogram. Ett undantag är den glansiga pekskärmen som genererar störande reflexer i dagsljus. I övrigt övertygar WQHD-panelen med utmärkta specifikationer och fungerar utmärkt inomhus. 

Bra inmatningsenheter är obligatoriska för en Latitude i den här prisklassen och E7470 gör oss inte besvikna. Detsamma gäller underhållsmöjligheterna: ta bara bort locket på undersidan och få tillgång till alla komponenter.

Den enda större nackdelen är batteritiden på bara 5:46 i vårt Wi-Fi-test. Det stämmer inte in med de höga förväntningarna eller det höga priset på 2300 euro. Versioner med HD eller FHD-skärmar bör vara lite mer uthålliga baserat på våra erfarenheter med 4K- och FHD-konfigurationer av samma modell.

Det starkaste alternativet är förmodligen HP:s EliteBook Folio 1040 G2, men den är dyrare även med en matt FHD-panel. Batteritiden är bättre, men Folio 1040 G2 har å andra sidan färre portar. Om priset är en begränsande faktor kan Lenovo ThinkPad T450s vara intressant. En jämförbar konfiguration börjar på omkring 1850 euro.
