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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8964 (minimum: 43 - maximum: 142900) Hz was measured.

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
38 ms ... rise ↗ and fall ↘ combined↗ 20.8 ms rise
↘ 17.2 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. » 95 % 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
48 ms ... rise ↗ and fall ↘ combined↗ 26.8 ms rise
↘ 21.2 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. » 78 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41 ms).

O Fire HD 8 (2018) da Amazon é um tablet de 8 polegadas que é praticamente inigualável em sua relação preço/desempenho. Se você está procurando um tablet acessível para navegar na web, definitivamente vale a pena considerar o Fire HD 8 (2018). Seu som estéreo era muito decente, assim como sua duração de bateria, sua qualidade geral de construção e seu Wi-Fi de banda dupla. A edição Kids apresenta um escudo protetor muito sólido e robusto em azul ou rosa, bem como conteúdo apropriado para crianças.

As diferenças entre o Fire HD 8 (2018) e seu antecessor, como a inclusão do Alexa, são quase insignificantes. No entanto, elas são muito bem-vindas e tornam o modelo mais novo ainda mais atraente do que o Fire HD 8 (2017), considerando seu preço idêntico de apenas $80.

Quando emparelhado com a estação de encaixe Show Mode opcional, o tablet oferecia os mesmos recursos do Echo Show da Amazon a um preço significativamente menor. No momento da escrita, o Echo Show de segunda geração é vendido por mais de $200, enquanto o modelo de 32 GB do pacote Fire HD 8 (2018) mais Show Mode Dock pode ser adquirido por apenas $140.

Dito isto, há algumas limitações que você vai encontrar mais cedo ou mais tarde, por exemplo, o um pouco letárgico MediaTek MT8163 SoC quad-core ou a tela escura de baixa resolução (1280x800). O tablet também não possui um chip GPS, a câmera é utilizável para fotos rápidas na melhor das hipóteses, e o sistema operacional Fire OS baseado no Android 7 é claramente voltado para os serviços da Amazon. A Play Store da Google pode ser instalada retroativamente, mas anulará sua garantia, portanto, cuidado.
