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
29.6 ms ... rise ↗ and fall ↘ combined↗ 6.8 ms rise
↘ 22.8 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. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.6 ms).
       Response Time 50% Grey to 80% Grey
50.8 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 32 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 85 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.9 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18071 (minimum: 5 - maximum: 3846000) Hz was measured.

In review: Acer TravelMate P449-M-7407. Review unit courtesy of Acer.

O Acer TravelMate P449 encaixa na classificação de "Trabalhador de talentos múltiplos e mestre em nenhum". É um aparelho bastante completo que traz muito para a mesa. Acerta em cheio quando se trata do tamanho; o chassi é pequeno e a iluminação suficiente para ser carregado com facilidade, mas a tela ainda é suficientemente grande para multitarefas e trabalho de escritório. A carcaça é atraente e profissional, o teclado se sente ótimo, e o desempenho é mais que adequado para o trabalho de escritório. A tela oferece alto contraste e ótimas cores. A ventoinha é notória somente sob uso intenso, mas as temperaturas são bem gerenciadas e o aparelho permanece frio, inclusive sob uso intenso. A seleção de portas é generosa com 5 portas USB, 2 opções de tela, e uma porta ethernet, e a bateria pode sobreviver todo um dia útil.

O Acer TravelMate P449 é uma boa opção  para profissionais que precisam de uma máquina portável e duradoura. Apesar de algumas desvantagens, é uma ótima opção para os guerreiros da estrada com baixo orçamento.

O TravelMate faz alguns sacrifícios para atingir a faixa de preços competitiva. A bela carcaça é fina e se sente barata, portanto, a sua durabilidade é uma preocupação. O touchpad é inconsistente e frustrante de usar, enquanto o leitor de digitais é quase inutilizável. A tela é escura e quase inútil em ambientes claros. A maioria das opções de conexão é lenta ou ultrapassada, e a CPU Skylake está desatualizada e tem afogamentos pesados.

Apesar dessas desvantagens, o Acer TravelMate P449-M-7407 continua sendo uma opção atraente no mercado empresarial sub $1000. No entanto, o preço do Lenovo ThinkPad E470 é difícil de ignorar. Por cerca de $720, o E470 oferece melhor desempenho e qualidade de construção, durações de bateria similares, uma boa tela IPS, e uma GPU dedicada. Por $130 a mais, o ThinkPad pode ser equipado com um Kaby Lake i7-7500U e 16 GB de RAM. Tenha em mente que esses modelos não vem com um SO e podem estar disponível somente em mercados educativos. O ThinkPad E470 é uma sólida recomendação sobre o TravelMate. No entanto, se o E470 não estiver disponível, o P449 é uma ótima segunda escolha.
