Business Kaby Lake Notebook Security Touchscreen Ultrabook Windows

Virado de cabeça. Um portátil empresarial com um pacote completo sem preocupações - já visível desde o momento de abrir a caixa. Mas os acessórios abundantes não conseguem esconder as fraquezas.

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
32 ms ... rise ↗ and fall ↘ combined	↗ 18 ms rise
32 ms ... rise ↗ and fall ↘ combined	↘ 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. » 80 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (26.7 ms).
↔ Response Time 50% Grey to 80% Grey
46 ms ... rise ↗ and fall ↘ combined	↗ 22 ms rise
46 ms ... rise ↗ and fall ↘ combined	↘ 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 0.9 (minimum) to 636 (maximum) ms. » 70 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (42.8 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

212 Hz

30 % brightness setting

The display backlight flickers at 212 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 212 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.

Fujitsu Lifebook T937 - provided by Fujitsu Germany

O Fujitsu Lifebook T937 deixa uma impressão mista no teste. Enquanto muitas características indicam um portátil sólido e com os pés no chão, sem experiências, ainda existem algumas fraquezas que não deveriam acontecer por esse preço. O aparelho não apenas se sai mal nos benchmarks, mas também tem algumas pausas inexplicáveis de tempos em tempos. Em combinação com o touchpad que aparece antiquado e o mecanismo rotativo da tela que parece antigo, você pode vê-lo como um aparelho para mais velhos e também para uma audiência que não é dissuadida pelo alto preço. No entanto, é questionável se sua visão, enfraquecida com a idade, pode compensar o baixo brilho da tela.

Um portátil sólido e nada emocionante, com fraquezas desagradáveis.

Além da tela ser muito escura e dos benchmarks fracos, há apenas pontos positivos para relatar: acabamento sólido, boa duração da bateria, muitas conexões e dispositivos de entrada, e a excelente adição de acessórios. Se você considerar o preço justificado, ainda pode ser o dispositivo ideal para o público-alvo.
