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
32 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 14.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 81 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
40.8 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 18.8 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. » 48 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41 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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9254 (minimum: 43 - maximum: 142900) Hz was measured.

A Dell acertou em cheio. O Inspiron Chromebook 14 2-em-1 (Inspiron 7486) é de longe o melhor Chromebook que testamos. A qualidade de construção está a par com o Pixelbook, a tela é bonita, a caneta incluída e o suporte para caneta EMR são bônus maravilhosos, e o desempenho excede quase todos os outros dispositivos Chrome OS.

O Core i3-8130U é talvez o processador perfeito para o Chrome OS; o chip equilibra perfeitamente o desempenho com o calor e o consumo de energia para oferecer uma experiência sumamente fluente com pouca ou nenhuma saída de calor e ruído do ventilador. As durações de bateria também são excelentes.

Temos algumas queixas menores. Os alto-falantes são claros, mas fracos, o que é uma pena, considerando o potencial de reprodução de mídia. O dispositivo também é um pouco mais pesado que outros 2-em-1 devido à tampa densa da tela. A tela de 14 polegadas torna o dispositivo um pouco difícil de segurar no modo tablet também.

Finalmente, está o preço. $600 é pedir muito para um dispositivo Chrome OS. Apesar da integração com o Android, o Chromebook 14 Inspiron ainda é um Chromebook no final do dia. Como tal, é um pouco limitado em comparação com os portáteis tradicionais Windows ou Mac. Dito isso, esse é possivelmente o melhor Chromebook no mercado atualmente. Ele supera o Pixelbook na maioria das áreas por $400 a menos. A maioria dos consumidores, estudantes e profissionais que trabalham, encontrarão muito para gostar no Chromebook Inspiron 14. Dependendo do seu fluxo de trabalho, o Chrome OS com Android pode ter tudo de que um usuário precisa.

O Chromebook Inspiron 7846 14 2-em-1 é o Chromebook dos sonhos dos usuários avançados de Chrome. Além de sua excelente qualidade de construção, dispositivos de entrada sólidos e excelente suporte para caneta EMR, o Chromebook Inspiron 14 oferece desempenho superior e melhor tela do que o carro-chefe Pixelbook da Google, com quase metade do custo. O Chrome OS tem uma nova estrela.
