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 (20.9 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 (32.8 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 8705 (minimum: 5 - maximum: 343500) Hz was measured. | ||

Dell, felsefesine sağlık kalıp iş cihazları üzerinde güncel modellerinde herhangi bir özelliği çıkarmıyor. 14 inçlik cihaz iyi ele alınmış ve iş kullanımı hatta diğer alanlar için de oldukça iyi. Sadece parlak dokunmatik ekran gün ışığı altında rahatsız edici yansımalara sahip. WQHD ekran harika özellikleri ve iç mekan kullanımı ile göz dolduruyor. Harika arayüzler üst sınıf bir Latitude için olmazsa olmaz ve E7470 bu konuda hayal kırıklığı yaratmıyor. Güvenlik için de aynısı geçerli. Bakım imkanlarını da takdir etmek gerekli, sadece alt kapağı çıkararak tüm bileşenlere ulaşmak mümkün.
Tek eksiklik ise 6 saate yakın olan WiFi kullanım süresi. Bu 2300 Euroluk bir cihaz için yüksek beklentiyi düşüren bir nokta.
