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
32 ms ... rise ↗ and fall ↘ combined↗ 18 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. » 81 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
39.6 ms ... rise ↗ and fall ↘ combined↗ 21.6 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. » 44 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.6 ms).

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 352.1 Hz ≤ 99 % brightness setting

The display backlight flickers at 352.1 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 352.1 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 13646 (minimum: 43 - maximum: 2500000) Hz was measured.

Contra

- A Lenovo usa diferentes telas para as variantes AMD e Intel
- PWM usado para a tela no modelo da Intel
- Bleeding da iluminação de fundo no modelo Intel
- O modelo AMD tem uma tela mais escura que o modelo Intel
- Altos desvios Delta E 2000 em ambas as telas
- Baixa cobertura do espaço de cores
- Sem portas futuristas
- O modelo AMD tem um desempenho de Wi-Fi inferior
- A CPU Intel é afogada com a bateria

O Lenovo IdeaPad S540 oferece bastante desempenho a um bom preço, independentemente de qual versão você comprar. O S540-14IWL e -14API custam cerca de € 800 (~ US$897) e são idênticos, exceto por ter diferentes CPUs e GPUs.

Por um lado, o S540-14API oferece melhor desempenho multi-core do que o S540-14IWL, graças ao seu processador Ryzen 7 3700U. No entanto, enquanto a Radeon RX Vega 10 é poderosa pelos padrões de GPU integrados, ela fica aquém da GeForce MX250 na S540-14IWL. O RX Vega 10 também não possui VRAM dedicada, usando 2 GB dos 8 GB de RAM. Efetivamente, isso deixa o S540-API com apenas 6 GB de RAM para os 8 GB no S540-IWL, já que a GeForce MX250 tem 2 GB de VRAM GDDR5 dedicada.

A tela tem sido frequentemente o ponto fraco de portáteis recentes da AMD que analisamos, e o S540-14API não é diferente. O dispositivo tem um painel mais escuro do que sua contraparte com tecnologia Intel. O bleeding da luz de fundo e o PWM não são problemas que estão presentes no S540-14IWL. No entanto, ambos as telas têm fortes desvios delta E-2000 e pequenas coberturas de espaço de cor.

O Lenovo IdeaPad S540-14IWL e o -14API são ambos excelentes portáteis multimídia de 14 polegadas. Eles são bem construídos, bom valor para o dinheiro e vão poder realizar a maioria das tarefas que você possa jogar neles. Ambos estão aquém de alcançar as melhores pontuações por diferentes razões.

Gostamos do design simples e elegante, que parece moderno e discreto. O chassi de alumínio também é resistente, assim como a tampa da tela. O IdeaPad S540 também tem uma boa seleção de portas, embora a inclusão do agora ultrapassado HDMI 1.4b pareça míope, assim como a decisão de omitir o suporte para DisplayPort ou Thunderbolt da única porta Type-C. Essas mudanças, junto com a troca do conector de energia por uma segunda porta Type-C, teriam garantido o futuro do S540 pelo menos nos próximos dois a três anos.

Ambos os dispositivos possuem armazenamento NVMe rápido, o que ajuda o sistema a funcionar sem problemas. Você sempre pode substituir a unidade por uma maior, mas 512 GB devem ser suficiente para a maioria das pessoas. Também gostamos que a Lenovo tenha decidido não incluir uma baia de 2,5 polegadas, pois isso permitiu que incluíssem uma potente bateria de 48 Wh. O S540-14IWL tem melhor duração de bateria que seu irmão com tecnologia AMD, mas ambos duram um dia inteiro entre as cargas.

No geral, quase nada separa o S540-14IWL do -14API. A GPU NVIDIA no anterior oferece melhor desempenho gráfico e de jogos do que a GPU integrada RX Vega 10, enquanto a Ryzen 7 3700U tem a vantagem sobre o Core i5-8265U em tarefas com múltiplos núcleos. Em última análise, é um caso que importa mais para você.
