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 detected 240.4 Hz ≤ 99 % brightness setting

The display backlight flickers at 240.4 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 240.4 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8933 (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
4 ms ... rise ↗ and fall ↘ combined↗ 2 ms rise
↘ 2 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 1 % 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
4.8 ms ... rise ↗ and fall ↘ combined↗ 2.8 ms rise
↘ 2 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 1 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41 ms).

O Samsung Galaxy Tab S4 é atualmente o tablet Android mais potente do mercado. A grande tela Super AMOLED é particularmente convincente, enquanto a sua integração com o DeX é excelente para a produtividade, embora existam limitações na sua utilização para jogos e multimídia. Os 64 GB de armazenamento e 4 GB de RAM também são abundantes, embora seja uma pena que a Samsung não venda o de 256 GB em mais regiões e atualmente limita-a apenas à versão Wi-Fi. A S Pen sem bateria também continua sendo uma ótima ferramenta.  

O Samsung Galaxy Tab S4 é um fantástico tablet que ganha a coroa dos tablets Android graças à sua excelente tela e à atual falta de alternativas viáveis.

No entanto, a Samsung errou o alvo ao tentar criar um tablet de gama alta com uma sensação de qualidade superior. A empresa equipou o Tab S4 com o SoC carro chefe do ano passado, enquanto seu armazenamento, memória RAM e câmeras são mais compatíveis com um smartphone de gama média do que um dispositivo carro chefe de 2018. A S Pen de plástico e a capa de teclado opcional apenas aumentam a nossa impressão de que a Samsung poderia ter ido mais longe ao oferecer uma experiência de tablet de nível de carro chefe.

O Tab S4 está a partir de $649,99 (£599) no site da Samsung, que sobe para $749 para a versão de 256 GB Wi-Fi nos Estados Unidos e para $729,99 (£649) para a variante LTE. No entanto, a maioria dos tablets Android são consideravelmente mais baratos, dos quais o Huawei MediaPad M5 Pro é atualmente a melhor alternativa. Seus acessórios opcionais são difíceis de encontrar, e também fica aquém do Tab S4 em geral.
