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
28.8 ms ... rise ↗ and fall ↘ combined↗ 10.8 ms rise
↘ 18 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 0.8 (minimum) to 240 (maximum) ms. » 66 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.7 ms).
       Response Time 50% Grey to 80% Grey
38.4 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 21.2 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. » 38 % of all devices are better.
This means that the measured response time is better than 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 not detected

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6262 (minimum: 43 - maximum: 142900) Hz was measured.

Skylake-uppdateringen av Latitude 7000-serien gör oss inte besvikna. Dells E7270 är en solid och välutvecklad produkt på företagsmarknaden som särskilt tilltalar med sitt smidiga format. Skärmen har en hög ljusstyrka på över 300 nits, vilket är mer än Dell anger, batteritiden är enastående och enheten är mycket kompakt, lätt och tunn. 

Tack vare den robusta höljet behöver man inte behöver oroa sig för enheten under transport. Dessutom är E7270 extremt flexibel, med en mångfald av portar som är idealiskt placerade. Datorn gör ett mycket bra jobb som mobil kontorsmaskin. Företagstypiska säkerhetsfunktioner och dockningsport finns också på plats.

Vi lämnar köprekommendation för målgruppen (mobila företagsanvändare). Detsamma gäller dock rivalerna HP 820 G3 och Lenovo ThinkPad X260. Detaljerna avgör vilken som är bäst för en viss användare. Latitude-datorn har ingen Trackpoint, vilket är vanligt bland bärbara företagsdatorer. 

Den utmärkta batteritiden med det stora 55 Wh-batteriet är ett annat starkt argument, men det är också Lenovos flexibla Power Bridge-teknik. En annan svaghet i E7270 är skärmens färgåtergivning, men Lenovos enhet är bara något bättre (HP:s modell testades med HD-skärm, vilket blir en orättvis jämförelse).

Tittar man bortom de rena företagsmodellerna är Dells egna XPS 13 intressant, då den är billigare, har bättre och större skärm, en mer modern design med tunna ramar, samt Thunderbolt. Å andra sidan finns inte samma flexibilitet och den saknar företagsspecifika funktioner.
