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
24 ms ... rise ↗ and fall ↘ combined↗ 7 ms rise
↘ 17 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 0.1 (minimum) to 240 (maximum) ms. » 48 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.6 ms).
       Response Time 50% Grey to 80% Grey
54 ms ... rise ↗ and fall ↘ combined↗ 28 ms rise
↘ 26 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. » 89 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.9 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18080 (minimum: 5 - maximum: 3846000) Hz was measured.

In review: Yoga Book Android. Test model provided by Lenovo Germany.
In review: Yoga Book Android. Test model provided by Lenovo Germany.

O Yoga Book ocupa um lugar especial em nossos corações e roda bem, inclusive com Android. De fato, em algumas áreas, ele inclusive consegue superar o tablet Windows. O design deste aparelho é único e é um verdadeiro prazer ver as dobradiças "watchband" em ação. O teclado Halo iluminado tem um ótimo visual e funciona bem no uso do dia a dia, mas recomendamos manter o aparelho longe de áreas ensolaradas. De outra forma, você sentirá falta de um teclado físico muito em breve.

O Yoga Book faz um ótimo trabalho digitalizando notas. Este é um ótimo plus para profissionais que tomam muitas notas e desejam uma tela táctil e um tablet de gráficos simultaneamente. O iPad Pro 9.7 não pode competir com esta oferta. De vez em quando, o modelo de teste demorou um pouco para reconhecer o conteúdo ou executar uma ação. Os usuários profissionais devem levar um pouco de tempo para sentir este dispositivo (especialmente o tablet de gráficos) antes de entregar seu dinheiro.

O desempenho e a tela são bons, mas não extraordinários. Eles bastarão para as tarefas do dia a dia. A tela pode ter desvios de cores muito altos para o uso profissional. Afortunadamente o aparelho quase não esquenta e o desempenho pleno sempre está disponível. Os bons alto falantes, a sólida carcaça e os dispositivos de entrada muitos flexíveis completam o Lenovo Yoga Book Android.

Apreciamos a longa duração da bateria. A barra Android foi ajustada para ser funcional e fácil de usar.

Prático, funcional, flexível e sem falhas maiores: o Yoga Book com Android é definitivamente um aparelho de nicho, mas é muito de divertido para se trabalhar.

Se você não precisa de Windows 10, recomendamos dar uma olhada na versão Android, dado que pode superar o aparelho Windows em algumas áreas: duração da bateria e tela.

Em resumo, a Lenovo está oferecendo uma ferramenta exclusiva para os designers gráficos que desejem um tablet portável. O Yoga Book também consegue ganhar pontos em termos de design e visual, graças à sua fabulosa carcaça e singulares dobradiças. O aparelho oferece tudo isto sem falhas maiores. Recomendamos que os compradores potenciais a dar uma olhada no Yoga Book Android.
