Breve Análise do Portátil Dell Chromebook 11 3181 (Celeron N3060)

Sam Medley, 👁 Allen Ngo (traduzido por Ricardo Soto), 10/25/2018

Low Quality. O Chromebook 11 padrão da Dell deixa um pouco a desejar. Uma tela de baixa qualidade e construção barata estragam o dispositivo. Além disso, os limites do Chrome OS e os bugs com a compatibilidade de aplicativos para Android deixam um gosto ruim.

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
12 ms ... rise ↗ and fall ↘ combined↗ 7.6 ms rise
↘ 4.4 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 9 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
32 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 10 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. » 18 % of all devices are better.
This means that the measured response time is better than 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 8773 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Dell Inspiron Chromebook 11. Review device courtesy of Dell.

O Dell Chromebook 11 3181 é uma história de muito pouco, muito tarde. O dispositivo parece ter cerca de dois anos, apesar de seu lançamento relativamente recente. Isso é aumentado pelo desempenho sem brilho do dispositivo, baixa qualidade de construção e tela horrível. Não há razão para considerar o Chromebook 11 3181 quando o irmão 2-em-1 pode ser adquirido por apenas $50 a mais. O formato conversível do 2-em-1 é muito mais adequado para a integração de aplicativos Android, e a qualidade de construção do 2-em-1 é muito superior.

Apesar de ter sido lançado recentemente, o Chromebook Dell Inspiron 11 (Chromebook 11 3181) já parece velho. Considerando que o dispositivo é superado de várias maneiras pelo Acer C740, um Chromebook lançado há três anos, o Chromebook 11 3181 certamente não está se esforçando entre os dispositivos econômicos.
