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
34 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 87 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.3 ms).
       Response Time 50% Grey to 80% Grey
20 ms ... rise ↗ and fall ↘ combined↗ 5 ms rise
↘ 15 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 5 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.1 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 detected 1000 Hz ≤ 100 % brightness setting

The display backlight flickers at 1000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 100 % 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: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9986 (minimum: 43 - maximum: 588200) Hz was measured.

Büyük ses getiren sessiz bir hikaye: Acer'ın Switch Alpha 12 modeli sadece düşük fiyatıyla değil aynı zamanda inovatif soğutma teknolojisi ile de meydan okuyucu. 12 inçlik dönüştürülebilir model iyi bir yapım kalitesine sahip ve neredeyse iki kat pahalı olan rakiplerinin hemen hemen hiç gerisinde değil.

Biraz ağır olmakla beraber, tablet gündelik kullanım için daha hafif olabilirmiş. Arayüzler en pahalı Microsoft modelleri ile aynı seviyede. Acer'ın yeni dönüştürlebilir modelinin ekranı da etkileyici. Fansız performansın iz düşümü elbette merak uyandırıcı. Güçlü Intel Core i5 işlemci fansız rakiplerinin gerisinde kalmıyor. Bu soğutma tasarımı ile üretici tablet ve ince laptoplar için geleceğe dönük bir çözüm sunmuş olabilir. Eğer Acer batarya kullanım sürelerini de arttırabilirse rakiplerini zor duruma sokabilir.
