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 | ||
|---|---|---|
| 36.4 ms ... rise ↗ and fall ↘ combined | ↗ 21.2 ms rise |  |
| ↘ 15.2 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 | ||
| 48.4 ms ... rise ↗ and fall ↘ combined | ↗ 24.4 ms rise |  |
| ↘ 24 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. » 82 % of all devices are better. This means that the measured response time is worse than 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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17903 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Quando a Dell anunciou o XPS 15 2-em-1, os usuários esperavam um XPS 15 padrão, mas com dobradiças de 360 graus. O que obtivemos foi um chassi completamente diferente com uma série de CPU/GPU não comprovada que pode ter afastado a base de fãs do XPS 15 principal. O Lenovo Yoga C940-15 está realmente mais próximo do que a maioria dos usuários imaginou que o XPS 15 2-em-1: uma tela táctil conversível com um teclado chiclet tradicional, CPU tradicional Intel Core H, GPU GeForce GTX, armazenamento facilmente reparável e um slot para caneta mais seguro em vez de um magnético.
Ter uma GPU GTX com capacidade para jogos em um formato conversível de 15,6 polegadas tem suas desvantagens. Ou seja, o modo tablet é melhor usado com moderação ou durante períodos curtos devido ao peso e tamanho da unidade. Mesmo assim, o Yoga C940 ainda é mais leve, brilhante, menor e mais poderoso do que os concorrentes 2019 HP Spectre x360 15 para torná-lo a melhor opção geral nessa categoria específica. O XPS 15 9575 2-em-1 é um pouco menor, mas fica aquém da maioria dos outros aspectos, incluindo desempenho, duração da bateria, brilho e áudio. Esperamos que as iterações futuras melhorem o peso, as teclas suaves do teclado e o clickpad.
O Lenovo Yoga C940-15 oferece um desempenho por volume muito alto para um conversível de 15,6 polegadas. Embora não seja particularmente leve ou barato por cerca de US$ 1.500 no varejo, é a opção superior quando comparado ao XPS 15 2-em-1 ou ao atual HP Spectre x360 15.
