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 detected

215.5 Hz

The display backlight flickers at 215.5 Hz (worst case, e.g., utilizing PWM) .

The frequency of 215.5 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 8743 (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
8 ms ... rise ↗ and fall ↘ combined	↗ 5 ms rise
8 ms ... rise ↗ and fall ↘ combined	↘ 3 ms fall
The screen shows fast response rates in our tests and should be suited for gaming. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 18 % of all devices are better. This means that the measured response time is better than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
10 ms ... rise ↗ and fall ↘ combined	↗ 5 ms rise
10 ms ... rise ↗ and fall ↘ combined	↘ 5 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 0.165 (minimum) to 636 (maximum) ms. » 20 % of all devices are better. This means that the measured response time is better than the average of all tested devices (32.9 ms).

Veredicto – Para quem procura algo sólido

O Samsung Galaxy M21 oferece um sistema de câmera medíocre e um nível de desempenho medíocre. Outros fabricantes estão perseguindo especificações e colocando ênfase no desempenho da câmera. A Samsung constrói apenas smartphones sólidos, que não têm fraquezas e oferecem alguns recursos especiais além.

O Galaxy M21 está no lugar exato, que smartphones muito mais expressivos com bateria muito boa e telas OLED brilhantes costumavam ocupar.

O Samsung Galaxy M21 é um smartphone sólido como uma rocha, de gama média inferior, com uma tela excelente e bateria com boa duração.

O Samsung Galaxy M21 é um smartphone sólido como uma rocha, de gama média inferior, com uma tela excelente e bateria com boa duração. Não é tão eficiente em termos de energia ou poderoso quanto os SoCs da concorrência, mas ainda oferece um nível de desempenho bastante decente.

No dia-a-dia, o Galaxy M21 é bom, e traz para a mesa tudo que um smartphone dessa faixa de preço deveria oferecer.
