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. » 75 % 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)
Screen flickering / PWM detected | 1000 Hz | ≤ 90 % brightness setting | |
The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering. 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. |

Artılar
Eksiler
Dell'in Latitude 12 E5270 modeli birçok güvenlik özelliğine sahip bir iş cihazı. Yeni Skylake işlemci ile önceki modele göre performansta biraz artış mevcut. Batarya kullanım süresi de biraz daha geniş kapasite ile biraz olsun artmış. Cihazda kullanılan tüm bileşenler uzun zaman kullanım için planlanmış. Güvenlik özellikleri oldukça geniş. Bağlantı noktaları düşünülerek konumlandırılmış ve docking istasyonu için de alan açışmış. Olası kullanıcılar bu detayları beğenecektir. Zaten sadece Latitude adı kalite ve iyi üretimin simgesi sayılabilir.
Elbette bazı eleştirilerimizi de belirtmemiz gerekli. Ekran kesinlikle eski ve bu fiyat aralığındaki bir cihaza ait değil. Daha yüksek bir ödemeyle elbette daha iyi ekran seçenekleri sunuluyor. Ancak bu modelin fiyatı da ucuz sayılmaz. Ekranın düşük parlaklığı yüzünden özellikle dış mekanlarda çalışması zorlaşıyor. Hızlı bir SSD olmasını özellikle bir iş cihazında çok isterdik, hele ki SSDlerin fiyatlarının oldukça düştüğünü göz önünde bulundurursak.
