Screen Flickering / PWM (Pulse-Width Modulation)
| 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
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.
