Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

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 8705 (minimum: 5 - maximum: 343500) Hz was measured.

Display Response Times

ℹ

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
24.4 ms ... rise ↗ and fall ↘ combined	↗ 13.6 ms rise
24.4 ms ... rise ↗ and fall ↘ combined	↘ 10.8 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 0.1 (minimum) to 240 (maximum) ms. » 54 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms).
↔ Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined	↗ 21 ms rise
42 ms ... rise ↗ and fall ↘ combined	↘ 21 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 64 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 ms).

Em nossos testes, o CAT S31 prova ser o dispositivo que o fabricante promete: Um smartphone reforçado que pode lidar com quase todos os ambientes. O fato de os internos técnicos não estarem atualizados com os últimos desenvolvimentos pode ser aceito, mas os potenciais clientes podem escolher a AGM, concorrente muito mais barata. Como um smartphone puro, o S31 é um dispositivo de nível de entrada com um sistema estável e um desempenho sólido. Aplicativos simples e atividades do navegador não são problema para o dispositivo. Se você quiser, pode até mesmo controlá-lo com luvas.

O CAT S31 é um smartphone sólido cuja tarefa principal é não quebrar. Ele consegue isso em qualquer caso, mas os usuários têm que fazer sem aplicativos exigentes.

Comprar um dispositivo tão robusto é muitas vezes uma decisão por instinto. As certificações e o design áspero e angular são oferecidos por todos os fornecedores de tais dispositivos. Se o CAT S31 pode realmente suportar as condições mais extremas, só pode ser visto através de um teste de resistência na respectiva área de aplicação do seu usuário. O S31 deixa uma impressão muito sólida, mas o preço elevado não pode ser justificado somente pelo desempenho e carcaça.
