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 0.1 (minimum) to 240 (maximum) ms. » 73 % 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
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 0.165 (minimum) to 636 (maximum) ms. » 53 % 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)

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 8774 (minimum: 5 - maximum: 343500) Hz was measured.

In review: Dell Latitude 12 E7270. Test model coutesy of Dell Germany

Latitude 7000 serisinin Skylake güncellemesi hayak kırıklığı yaratmıyor. E7270 modeli ile Dell sağlam ve iyi geliştirilmiş özellikle mobiliteye odaklanmış bir cihaz sunuyor. Ekran çok yüksek parlaklığa sahip, batarya ömrü harika ve cihaz oldukça hafif ve ince. Sağlam kasası ile kullanıcının yolculuklar esnasında cihazın sağlamlığı konusunda endişe duymasına gerek yok. E7270 port çeşitliliği sayesinde de bağlantı olanakları yönünden oldukça zengin. E7270 bu sayede mobil bir ofis çalışanının tüm ihtiyaçlarını karşılayabilecek güçte.

Ancak cihazı iş amaçları için kullanmayacaksanız bir multimedia cihazı olan XPS 13 modeli de ilginizi çekebilir.
