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 24510 Hz60 % brightness setting

The display backlight flickers at 24510 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 60 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 24510 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6668 (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
26.4 ms ... rise ↗ and fall ↘ combined↗ 14.8 ms rise
↘ 11.6 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 49 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.7 ms).
       Response Time 50% Grey to 80% Grey
38 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 18 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. » 33 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (42.8 ms).

In review: The IdeaPad 520s-14IKB, provided by campuspoint.

O IdeaPad 520s-14IKB é um bom pacote geral que faz muitas coisas, mas tem fraquezas em alguns detalhes. No entanto, essas fraquezas podem ser desculpadas em grande medida pelo preço. Primeiro o positivo: Em comparação com o antecessor, o design é mais atraente e a carcaça não mostra fraquezas em termos de estabilidade e acabamento. A boa estabilidade também ajuda com a experiência de digitação, de modo que você também pode contar o teclado com os aspectos positivos, e o Touchpad que está de acordo com o padrão Precision da Microsoft. A duração da bateria é muito boa e melhorou claramente em comparação com o antecessor, dado que a Lenovo colocou uma bateria maior. O ventilador é muitas vezes desligado e quando funciona, ele funciona com um zumbido agradável e silencioso. Mesmo que a tela esteja longe de ser perfeita (cobertura de espaço de cores baixa), ela ainda pode mostrar os bons ângulos de visualização típicos do IPS e um contraste surpreendentemente alto.

Em princípio, a Lenovo fez todas as coisas mais importantes. Porém, há pequenas deficiências em alguns detalhes: Por exemplo, a carcaça esquenta muito quando sob uso intenso. No geral, o resfriamento não é muito adequado. Embora seja silencioso, houve um forte afogamento no teste de estresse. Já no Cinebench loop, a CPU não consegue manter seu desempenho máximo. Ainda é incompreensível para nós que a conexão USB-C integrada  não suporte o DisplayPort, nem possa ser usada para carregar. Que pena! Também é lamentável que a Lenovo apenas inclua uma placa WLAN 1x1.

No geral, o IdeaPad 520s é um bom poli funcional que convence com uma boa duração da bateria e um design atraente.

Os pontos negativos não são suficientes para conseguir uma recomendação para o IdeaPad 520s-14IKB. Simplesmente é um Ultrabook relativamente bem sucedido, que pode ser interessante para estudantes em particular, com boa duração da bateria, a dGPU e o teclado confortável. Se o comparar, por exemplo, com o popular Dell XPS 13, o IdeaPad é maior e mais pesado, mas ainda é muito portável e quase adequado para jogos com a GPU GeForce. Também é muito mais barato. 

Precisamos mencionar um pequeno qualificador para a recomendação, dado que, no momento do teste, o IdeaPad 520s-14IKB já está desatualizado. Uma nova versão do mesmo portátil com Core i5-8250U e GeForce MX150 seria muito mais atraente. No entanto, também precisamos perguntar o quão bem o resfriamento poderia lidar com os componentes mais novos.
