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 | ||
|---|---|---|
| 35 ms ... rise ↗ and fall ↘ combined | ↗ 8 ms rise |  |
| ↘ 27 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 92 % 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 | ||
| 36 ms ... rise ↗ and fall ↘ combined | ↗ 19 ms rise |  |
| ↘ 17 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. » 46 % of all devices are better. This means that the measured response time is similar to 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 detected | 1000 Hz | ≤ 20 % brightness setting |  |
The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % 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 8715 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Artılar
+ Çok iyi bakış açıları ve stabil ekran
+ Çok yüksek ekran çözünürlüğü
+ Üst sınıf yapım kalitesi
+ 512 GB SSD
+ Makul arayüzler
+ Pasif soğutma
+ Elegant tasarım
Eksiler
- İşlemci tam potansiyelini kullanamıyor
- Tatmin etmeyen batarya performansı
- 12 aylık standart garanti
Dell'in XPS 12 9250 modeli ince 12.5 inçlik bir dönüştürülebilir model. Kullanılan Intel Core m7 6Y75 işlemci rutin işlemler için yeterli performansa sahip. SSD yüksek okuma hızı ile hızlı performans sunuyor.Yüksek çözünürlüklü ekran yüksek kontrastı, renk gamı ve stabilitesi ile göz dolduruyor.
İlk bakışta elegant duran cihaz özelliklere baktıkça daha ilginç hale geliyor. Akla takılan soru ise Dell'in fiyatı çok yüksek tutmuş olması.
Tüm bunlara rağmen elbette eleştiriden kaçış yok. Ekran tam oturuş pozisyonu için ayarlanamıyor. Test cihazımızda en güçlü işlemci olmasına karşın performansın tamamen kullanılabildiğini söyleyemiyoruz. Microsoft'un Surface Pro 4 modeli Core m3 işlemci ile daha hızlı. Daha uzun batarya kullanımı da görmek istediklerimiz arasında.
