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
24.4 ms ... rise ↗ and fall ↘ combined	↗ 12.8 ms rise
24.4 ms ... rise ↗ and fall ↘ combined	↘ 11.6 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. » 53 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
39.2 ms ... rise ↗ and fall ↘ combined	↗ 20.4 ms rise
39.2 ms ... rise ↗ and fall ↘ combined	↘ 18.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 56 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 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 8774 (minimum: 5 - maximum: 343500) Hz was measured.

The Fujitsu LifeBook U748, provided by Fujitsu Deutschland.

O Fujitsu LifeBook U748 é um portátil empresarial sólido, assim como seu antecessor. A atualização da CPU melhora o desempenho a um custo para a duração da bateria, pois consome mais energia. No geral, o LifeBook U748 é um dispositivo impressionante com uma boa tela multi-touch e um teclado decente que é confortável para trabalhar. O ruído do ventilador é gerenciável, mesmo que às vezes possa ser frustrante, enquanto os alto-falantes e a webcam são bastante comuns. Esses dois componentes são frequentemente ignorados nos dispositivos empresariais.

O Fujitsu LifeBook U748 nos conquista com sua boa tela, SSD rápido e muitos recursos de segurança necessários para dispositivos empresariais. Infelizmente, o TouchPad abaixo da média e desatualizado permanece o mesmo do modelo do ano passado.

A Fujitsu equipou o LifeBook U748 com o mesmo, muito criticado TouchPad do seu antecessor. Em contraste, gostamos do design fino e da base estável, que parece e se sente premium. Uma boa seleção de portas completa o pacote, embora teríamos gostado de uma porta Thunderbolt 3.

O Fujitsu LifeBook U748 recebe uma recomendação nossa, pois oferece um bom pacote geral. No entanto, a concorrência continua a melhorar, e assim o LifeBook muitas vezes terá dificuldade em acompanhar o Lenovo ThinkPad T480s.
