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
28.8 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 12.4 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 0.8 (minimum) to 240 (maximum) ms. » 67 % 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
52.8 ms ... rise ↗ and fall ↘ combined↗ 39.2 ms rise
↘ 13.6 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. » 88 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (40.9 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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8758 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Dell Chromebook 11 3181 2-in-1. Test model provided by Dell US

Os Chromebooks percorreram um longo caminho desde a sua introdução há 7 anos. Naquela época, os fabricantes mudaram de oferecer aos consumidores um substituto de netbooks para atingir o grande (e lucrativo) mercado de educação. Embora os Chromebooks premium ainda possam ser encontrados (veja o Chromebook Pro da Samsung e o próprio Pixelbook do Google), o pão com manteiga desses dispositivos é a educação, e parece permanecer assim por algum tempo.

O Dell Inspiron Chromebook 11, ou Chromebook 11 3181, como nos referimos a ele, parece distintamente criado para esse mercado. Oferece uma boa combinação de baixo custo e alta durabilidade. Isso é importante para os estudantes que dispõem de pouco dinheiro e os distritos escolares com orçamento limitado. Os distritos escolares e as grandes organizações que procuram uma máquina resistente e duradoura para acessar os aplicativos da web encontrarão muito do que gostar com esse Chromebook, desde que possam arcar com as despesas. Afinal, existem Chromebooks mais baratos que funcionam tão bem quanto, se não melhor, que o Chromebook 11 3181. O Acer Chromebook 14, por exemplo, vem com um processador quad-core mais potente (Celeron N3160 da Intel) em um corpo de alumínio mais elegante por cerca de $50 a menos, embora ele não tenha uma tela táctil ou o versátil formato 2-em-1 da Dell. 

O elefante na sala é o Android. Os Chromebooks estão em uma posição estranha no momento. O suporte a aplicativos para Android agora está totalmente disponível, mas há várias dificuldades para trabalhar. O formato conversível do Dell Inspiron Chromebook 11 posiciona o dispositivo para ser um portátil e um tablet Android, desde que a Google continue a abordar os problemas com a integração de aplicativos Android. O dispositivo se encaixa bem como um dispositivo complementar a um desktop tradicional; os alunos podem levar o Chromebook para a aula todos os dias sem se preocupar com que o dispositivo quebre ou morra, escrever suas notas e, em seguida, voltar para a área de trabalho em casa quando precisarem de um computador completo. 

O Dell Inspiron Chromebook 11 não abre novos caminhos para os Chromebooks, mas sabe o que está tentando ser. Este é um dispositivo utilitário para usuários utilitários. Por $280, definitivamente não vai danificar sua carteira. É feio, é limitado e não ganhará nenhum prêmio, mas o Dell Inspiron Chromebook 11 2-em-1 é uma opção barata para o trabalho de escritório básico e para jogos casuais raros.
