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
25 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 11 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 0.8 (minimum) to 240 (maximum) ms. » 35 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.9 ms).
       Response Time 50% Grey to 80% Grey
38 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 18 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 33 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (43.4 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: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5069 (minimum: 43 - maximum: 142900) Hz was measured.

Pro

+ CPU Kaby Lake
+ SSD veloz e HD grande
+ Muito silencioso durante o uso
+ Baixas temperaturas de superfície

Contra

- Teclado um pouco esponjoso
- Comportamento pulsante da ventoinha
- Brilho muito baixo para a luz do sol

O TravelMate P648 G2 M 7619 é um portátil leve e durável. Todas as necessidades para um dia de trabalho devem ser cobertas com uma CPU Kaby Lake atualizada, SSD mais rápido e HD maior. A tela é brilhante o suficiente para ainda poder funcionar mesmo em condições de luz desfavoráveis. A Acer oferece uma estação docking correspondente para expandir as opções de interface. O teclado poderia ser um pouco mais nítido e a Acer poderia ter controlado o comportamento pulsante da ventoinha.

E a Acer atualiza novamente sua série TravelMate P6. No entanto, não muito mudou além da moderna CPU Kaby Lake e armazenamento expandido do disco rígido.

O TravelMate P648 G2 M 7619 pode ser altamente recomendado para usuários empresariais à procura de uma alternativa para Lenovo, Dell e HP. Nosso modelo de teste está disponível por aproximadamente 1500 Euros (£1800).
