Business Kaby Lake Laptop / Notebook Security Windows

Negócios Inteligentes. A Dell está atualizando seus subportáteis de negócios da série 7000 com as atuais CPUs Kaby Lake Refresh e equipou o 7390 com um slot para cartão inteligente, além de outros recursos de segurança. Nosso extenso teste avalia se, além de ter uma duração de bateria muito longa, a tela, as conexões e os dispositivos de entrada também podem suportar as exigências de um profissional.

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
35.2 ms ... rise ↗ and fall ↘ combined	↗ 21.2 ms rise
35.2 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. » 90 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (25.7 ms).
↔ Response Time 50% Grey to 80% Grey
48.8 ms ... rise ↗ and fall ↘ combined	↗ 24.8 ms rise
48.8 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. » 81 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (41 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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9152 (minimum: 43 - maximum: 142900) Hz was measured.

The Dell Latitude 7390 - provided by Dell Germany

Com o novo Latitude 7390, a Dell fez quase tudo certo. Por, não tão altos, 1400 Euros (~$1732) para o modelo que testamos, você recebe um pacote completo com apenas alguns pontos fracos.

Devemos mencionar aqui o teclado um pouco pequeno, mas que na maioria das vezes é bem-sucedido, as medíocres teclas do mouse, a falta do Thunderbolt 3 e a ruidosa tecla de espaço. É um erro de projeto menor que a tampa levanta a base a partir de um ângulo de abertura acima de 135 °. A única coisa que realmente não gostamos foi o som detestável e o sensor de digitais sub-ótimo.

Não apenas os pontos da lista dos "Pros" são mais numerosos, mas principalmente os mais importantes. Mesmo com o seu i5-8350U, o Latitude é um pouco exagerado para tarefas de escritório, dado que a duração da bateria ainda está em um nível alto, dizemos que mais energia nunca faz mal. A carcaça de design simples, mas de alta qualidade, os dispositivos de entrada bons a muito bons, o equipamento de segurança completo, as conexões sensatas, a tela de alto contraste, o Windows 10 Pro e, finalmente, os 3 anos de garantia junto com a operação silenciosa, merecem uma recomendação de compra clara.
