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
30.8 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 14.4 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. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.6 ms).
       Response Time 50% Grey to 80% Grey
50.4 ms ... rise ↗ and fall ↘ combined↗ 27.6 ms rise
↘ 22.8 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. » 84 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (42.5 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: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8568 (minimum: 43 - maximum: 142900) Hz was measured.

In the review: Lenovo ThinkPad L470, provided courtesy of: CampusPoint

Com o L470, a Lenovo oferece um ThinkPad orientado para o orçamento, que, acima de tudo, deve ser interessante para estudantes e empresas.

Por um preço relativamente baixo, o L470 oferece o conhecido e excelente teclado ThinkPad, incluindo o TrackPoint. Também na caixa: Uma tela IPS Full HD, que não pode ser considerada como garantida nesta categoria de preço. A carcaça de plástico não se sente de qualidade alta, no entanto, se sente bastante robusta e possui dobradiças duráveis. Como portátil empresarial, o L470 oferece uma boa variedade de portas. Aqui, é preciso lamentar a falta de uma porta tipo USB tipo C, no entanto, isso é um pouco compensado pelo fato de que a Lenovo ainda integra uma porta docking dedicada. Portanto, não se depende das estações dock USB Tipo C. O que também é bom é que a Lenovo ainda equipa o L470 com uma porta VGA, que é uma característica única entre os ThinkPads atuais. Para escolas, universidades e empresas que ainda utilizam projetores antigos, este é um importante ponto de venda. Neste caso, a boa duração da bateria e a flexibilidade de uma bateria substituível devem ser apreciadas, embora ela eleve um pouco o aparelho. 

A Lenovo não cometeu grandes erros. Em primeiro lugar e acima de tudo nesta categoria está o irritante ruído da bobina, o que é uma grande pena, pois, de outra forma, o dispositivo teria sido completamente silencioso durante a o modo inativo. O afogamento da GPU, funcionando com a bateria, também é compreensível. A baixa cobertura do espaço de cores da tela não deve ser vista de forma negativa com um aparelho destinado aos negócios, mas deve ser mencionado, no entanto. Finalmente, é preciso criticar o período de garantia padrão, um ano não é suficiente.

O vencedor do preço/desempenho: Com um preço baixo e recursos legados, como uma porta VGA e uma bateria substituível, o L470 é um portátil empresarial interessante de 14 polegadas.

Apesar destas desvantagens, o L470 merece uma recomendação como um pacote de preço/desempenho atraente. Contra o seu concorrente interno mais próximo, o E470, o L470, um pouco mais caro, pode distinguir-se através de uma porta de estação docking dedicada, uma porta VGA e a bateria substituível. No entanto, com o Nvidia GeForce 940MX, o E470 é mais interessante para os gamers casuais. Acima de tudo, o L470 derrota os ProBooks 440640 da HP, graças à tela IPS, porque ambos os Probooks vêm com telas TN. O concorrente mais durão é o Dell Latitude 5480, que, em termos de preço, compete mais com o ThinkPad T470 que o L470.
