Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 820 Hz | ≤ 100 % brightness setting |  |
The display backlight flickers at 820 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 820 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17924 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Contra
Não há como negar que o Pixelbook se sente ótimo para segurar e usar. O próprio chassi é o melhor que a Lenovo, a HP e a Dell têm para oferecer na categoria conversível de subportáteis leves, se mantendo firme e surpreendentemente inflexível. Seria um belo concorrente no espaço dos Ultrabooks no caso improvável de ver um Pixelbook baseado em Windows.
Será que definitivamente podemos chamar o Pixelbook de o melhor Chromebook disponível? Embora seja definitivamente rápido e o mais caro, o Pixelbook sacrifica recursos importantes em comparação com os Chromebooks de $300 USD para satisfazer suas dimensões apertadas. Por um lado, a falta de um USB Type-A e de um leitor de cartões SD inevitavelmente se tornará um aborrecimento, especialmente em uma máquina tão portátil, onde a conectividade deve estar prontamente disponível. O HP Chromebook 13 G1 inclui ambas as opções que estão faltando com um processador mais rápido e as mesmas duas portas USB Type-C por cerca de $300 USD a menos. Além disso, a HP e a maioria dos Chromebooks de nível básico podem receber manutenções mais facilmente em comparação com a natureza fechada do Pixelbook que os entusiastas e os departamentos de TI apreciarão.
Outros detalhes menores estragam o que de outra forma é uma experiência excelente e barebone do Chromebook. A tela não está tão calibrada quanto a do Surface Pro ou MacBook Pro e os tempos de resposta mais lentos do preto-branco e cinza-cinza se tornam muito notórios ao navegar pela web no modo tablet. O SSD interno de 128 GB é superado por SSDs SATA III padrão e o teclado com barulho de alta frequência é muito perceptível se estiver em uma sala de aula ou biblioteca.
O Pixelbook é ideal para aqueles que querem um Chromebook duradouro, autossuficiente e amigável para viagens, que também, por acaso, tem um modo de tablet brilhante para aplicativos Android da Play Store. Se esses pontos fortes não são tentadores, então um Chromebook mais barato, como o Lenovo ThinkPad 13 ou Asus Chromebook Flip com suporte para Play Store, podem servir igualmente e com uma maior variedade de portas integradas.
O Pixelbook é fino e resistente ao custo elevado de ter menos recursos integrados. Sua leveza, forte apelo visual e modos versáteis 2-em-1 são retidos por suas opções de conectividade limitadas e uma tela que não é tão precisa quanto a melhor da Microsoft ou da Apple com ghosting e cintilações mais visíveis.
