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
30 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 13.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 73 % 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
49.6 ms ... rise ↗ and fall ↘ combined↗ 23.6 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 0.9 (minimum) to 636 (maximum) ms. » 83 % of all devices are better.
This means that the measured response time is worse than 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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9279 (minimum: 43 - maximum: 142900) Hz was measured.

A Lenovo continua sua linha Yoga de gama alta com o Yoga C940-14IIL e a equipou com os mais recentes processadores Ice Lake pela primeira vez. Esta é uma atualização evolutiva bem executada.

Sem dúvida, o novo Intel Core i7 2617M é o coração da tablet Yoga. Em termos de CPU e especialmente de desempenho da GPU, as novas plataformas de CPU trazem uma enorme melhoria no desempenho, o que torna o Yoga C940 adequado inclusive para jogos leves. Isso foi feito sem aumento de calor ou ruído - pelo contrário, há uma diminuição nas duas áreas. A duração da bateria continua sendo boa. Em comparação com o Yoga C930, existe uma tela FHD nova e mais brilhante, que é definitivamente uma melhoria bem-vinda. Além disso, a Lenovo carrega muitas coisas boas dos antecessores, como a construção de metal premium, a caneta integrada ou o forte sistema de alto-falantes quádruplos.

Quase não existem pontos fracos. Um dos poucos é definitivamente a falta de portas, bem como p pouco de ruído de bobina. Além disso, é desnecessariamente complicado abrir o Yoga C940 (pois os parafusos estão escondidos sob os pés de borracha). Seria bom também se a Lenovo oferecesse uma opção de tela mate e se o painel LCD atingisse o valor de brilho prometido de 400 cd/m².

A Lenovo não comete nenhum erro neste caso - e é por isso que o Lenovo Yoga C940-14IIL provavelmente entrará em muitas listas de desejos nesta temporada de férias.

Esses pontos fracos não são decisivos para nós. Podemos recomendar sinceramente o Lenovo Yoga C940-14IIL. É um portátil premium que oferece muita qualidade e flexibilidade, que os grupos-alvo, como os alunos, apreciarão. O Dell XPS 13 7390 2-in-1 tem um concorrente difícil aqui.
