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 | ||
|---|---|---|
| 36.8 ms ... rise ↗ and fall ↘ combined | ↗ 17.2 ms rise |  |
| ↘ 9.6 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 94 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 35.6 ms ... rise ↗ and fall ↘ combined | ↗ 19.2 ms rise |  |
| ↘ 16.4 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (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 (33.7 ms). | ||
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 | 27030 Hz | ≤ 67 % brightness setting |  |
The display backlight flickers at 27030 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 67 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 27030 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Contra
- A sustentabilidade do Turbo Boost poderia ter sido melhor
- Sem Thunderbolt 3, HDMI ou leitor de cartões SD
- As cores poderiam ter sido melhor calibradas
- Ruído da ventoinha de alta frequência sob uso intenso
- As teclas têm uma resposta fraca
- Brilho médio da tela
- Tempo de recarga lento
- Sem opção 4K UHD
- RAM soldada
A Lenovo posicionou o Yoga C740-14 muito bem no mercado atual. É centenas de dólares a menos do que o Dell XPS 13 7390 2-em-1 e Asus ZenBook Flip 14 quando configurado com as mesmas capacidades de RAM e armazenamento, oferecendo um tamanho de tela maior que o HP Spectre x360 13. O melhor de tudo é que o Yoga C740 mantém uma aparência de alta qualidade que muitos usuários esperam de um modelo carro-chefe, mesmo se vendendo por muito menos. É uma ótima opção intermediária se você não se importa com os recursos de 4K, Thunderbolt 3 ou Ice Lake.
Ainda existe uma lista de desvantagens que se somam. O bleeding moderado da luz de fundo irregular, a tela relativamente fraca, as cores mal calibradas, as teclas esponjosas do teclado e o ruído agudo do ventilador quando sob uso intenso tornam a experiência geral não tão sólida quanto poderia ter sido. Ainda assim, é um conversível completo, dado o preço, e definitivamente vale a pena o investimento extra sobre algo como o horrível HP Pavilion 11-n070eg x360 ou o barato VivoBook Flip.
O Lenovo Yoga C740-14 é um dos melhores portáteis conversíveis em sua categoria de gama média, porque parece e se sente mais próximo dos modelos mais caros de gama alta sem custar mais.
