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
30.4 ms ... rise ↗ and fall ↘ combined↗ 15.6 ms rise
↘ 14.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.1 (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 (21.6 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 19.6 ms rise
↘ 24.4 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. » 69 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.8 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 detected 922 Hz ≤ 20 % brightness setting

The display backlight flickers at 922 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 922 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18034 (minimum: 5 - maximum: 3846000) Hz was measured.

The Dell Latitude 7285, provided by Dell Germany

Com o Dell Latitude 7285, o fabricante nos apresenta um conversível de muita alta qualidade com componentes modernos. O Intel Core i5-7Y57 oferece um desempenho sólido e está à altura para tarefas do escritório do dia a dia. A CPU também pode lidar com aplicativos multimídia. Muitas vezes, o SoC frugal pode manter-se bem com os processadores ULV mais rápidos. 2.300 Euros (~$2740) por um aparelho com o equipamento de nossa unidade de teste é o que o usuário final tem que pagar. No entanto, os clientes recebem um dispositivo perfeitamente construído, o que dá uma impressão de muito alta qualidade em todos os aspectos.

O preço de venda pode assustar muitos no início, mas a Dell oferece um dispositivo muito bem construído com uma tela 3K de primeira classe e uma seleção de conexões modernas. Além do tablet e da base de teclado, o pacote também inclui o Dell Active Pen e uma garantia de 36 meses.

Gostamos da muito boa seleção de materiais e do design moderado. O Dell Latitude 7285 recebe muito boas marcas pela tela, o que fornece um brilho muito alto e também pode exibir o espaço de cores muito bem. Francamente, teríamos esperado menos desempenho no processador, mas, como a Dell não o opera com o seu TPD de 4,5 watts, o desempenho está ligeiramente acima de nossas expectativas. Todos os resultados do teste, sem exceção, mostram que o Dell Latitude 7285, baseado no Intel Core i5-7Y57 pode competir bem contra a concorrência.

No consumo de energia, o dispositivo nos decepcionou um pouco, porque esperávamos valores muito melhores dos componentes frugais. Isso resultou também nos resultados confusos da duração da bateria. A ideia de colocar uma bateria adicional na base do teclado é boa e evita uma posição pior em nossa comparação de testes.
