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 8746 (minimum: 5 - maximum: 343500) Hz was measured.

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
25 ms ... rise ↗ and fall ↘ combined↗ 7 ms rise
↘ 18 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. » 55 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
   ↔    Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 28 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. » 71 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.9 ms).

In review: Acer TravelMate P648-M-757N. Test model provided by Notebooksbilliger.de

Com o TravelMate P648-M, a Acer oferece um portátil empresarial bem feito de 14-polegadas. O processador integrado oferece suficiente desempenho para todos os cenários de aplicação habituais. O computador sempre funciona de forma silenciosa e dificilmente esquenta. O veloz SSD garante um sistema veloz. É possível substituir o SSD. Isto requer a remoção do painel inferior do computador, o qual é fácil. Graças a um modem LTE, você pode se conectar à Internet via redes de telefonia celular. Você pode adicionar interfaces ao computador conectando uma estação docking Acer na porta docking no lado inferior do computador. O portátil fornece bons dispositivos de entrada e excelentes durações da bateria. A tela IPS do TravelMate possui ângulos de visão amplos e um contraste alto. No entanto, seu brilho é baixo demais. Esperamos mais de um computador nesta faixa de preços.

A Acer primeiramente atualizou o computador: Processador Skylake, RAM DDR4, e uma porta Thunderbolt-3. Estas mudanças razoáveis fizeram com que este portátil seja ainda melhor.

Quem estiver procurando por uma alternativa para as marcas estabelecidas como Lenovo, HP, e Dell deveria considerar o TravelMate. A Acer demonstra que e eles podem produzir portáteis empresariais.
