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 347 Hz ≤ 90 % brightness setting

The display backlight flickers at 347 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 347 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 10727 (minimum: 43 - maximum: 588200) 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
34 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 14 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. » 87 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26 ms).
       Response Time 50% Grey to 80% Grey
47 ms ... rise ↗ and fall ↘ combined↗ 24 ms rise
↘ 23 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. » 75 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (41.6 ms).

Pro

+ Carcaça funcional de alumínio e plástico
+ Touchpad muito bom
+ Teclado adequado
+ Digitalizador ativo incluído
+ Permanece sempre frio e quase silencioso
+ Melhor duração da bateria graças à bateria maior

Contra

- A CPU não usa toda sua capacidade
- Tela: baixo brilho e cobertura do espaço de cores, efeito de ondulação estranho, PWM
- USB-C sem DisplayPort ou fornecimento de energia
- As dobradiças são muito frouxas
- 1x1 WLAN
- Opções de GPU e CPU desatualizadas

Já mencionamos na seção sobre a carcaça, que o Yoga 520-14IKB é muito parecido com o IdeaPad 520s-14IKB. Isso não se aplica apenas ao design, mas também ao hardware em geral. O Lenovo Yoga 520-14IKB é quase a versão conversível do IdeaPad.

Portanto, a lista de pros e contras também são muito similares. Assim como no IdeaPad, a carcaça, teclado, e touchpad estão em um bom nível. Embora dispositivos mais caros possam até mesmo ser significativamente melhores aqui, até certo ponto, considerando o preço, você não pode pedir muito mais do Yoga, que não possui fraquezas reais nessas categorias. O mesmo também pode ser dito sobre a emissão de ruído e a temperatura. O Yoga 520-14IKB permanece sempre frio e silencioso. Além disso, graças a uma bateria maior, sua duração foi significantemente melhorada em comparação com o predecessor.

Encontramos a primeira diferença em comparação com o IdeaPad 520s-14IKB na temperatura. Enquanto o IdeaPad esquenta um pouco mais (também devido ao GPU da Nvidia, é claro), o Yoga 520 permanece sempre frio. Isso também é devido ao seu primeiro ponto negativo forte: o desempenho da CPU é limitado significativamente e permanece longe do possível máximo do Core i5-7200U. Esta limitação de desempenho se deve à limitação do TDP do fabricante de 8 watts para a CPU. Portanto, não é surpreendente que a carcaça quase não esquente dessa maneira. Outro ponto negativo é a tela. Embora ofereça a capacidade táctil e um digitalizador ativo, a qualidade da cor não é boa devido ao espaço de cores limitado. O brilho também é muito baixo para compensar a superfície brilhante em uso externo. Mas ficamos realmente aborrecidos com o efeito de onda estranho que pode ser visto no painel quando olhamos de perto e também pela baixa frequência de PWM. Além dessas fraquezas, como no IdeaPad também sentimos falta de uma conexão USB-C que lida com mais que USB aqui. Além disso, as dobradiças são muito balançantes para nosso gosto. E finalmente, como no IdeaPad 520s-14IKB, temos que reclamar sobre o WLAN 1x1.

As fraquezas da tela e o mau desempenho da CPU combinados com os componentes envelhecidos tornam o Yoga 520-14IKB um conversível que dificilmente pode ser recomendado.

Devido a essas fraquezas, é difícil para nós dar uma recomendação ao Yoga 520-14IKB. Em particular, os pontos fracos da tela e o desempenho da CPU pesam muito. Além disso, está o fato de que o Yoga 520-14IKB está simplesmente ultrapassado, dado que a GPU opcional e a CPU já possuem um sucessor. Portanto, nossa recomendação é para um conversível diferente, ou para aguardar uma atualização do Yoga com o Kaby Lake e oMX150. Talvez as coisas também funcionem melhor em termos de tela e desempenho da CPU.
