Breve Análise do Portátil Dell Latitude 7400: Mesmo a gama alta não está livre de fraquezas

Name: Dell Latitude 7400-8N6DH
Brand: Dell

Business High End. O portátil empresarial de 14 polegadas da Dell possui uma bateria de longa duração, um excelente teclado e um SSD NVMe rápido. A tela IPS mate, no entanto, pode ter um brilho máximo maior. Além disso, o ventilador emite um zumbido agudo.

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
37.6 ms ... rise ↗ and fall ↘ combined	↗ 21.2 ms rise
37.6 ms ... rise ↗ and fall ↘ combined	↘ 16.4 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 94 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (24.6 ms).
↔ Response Time 50% Grey to 80% Grey
62 ms ... rise ↗ and fall ↘ combined	↗ 29.6 ms rise
62 ms ... rise ↗ and fall ↘ combined	↘ 32.4 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 96 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (39.1 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17957 (minimum: 5 - maximum: 2500000) Hz was measured.

In review: Dell Latitude 7400 (8N6DH). Test model provided by:

O Dell Latitude 7400 é um pouco mais compacto e mais leve que o seu predecessor. O dispositivo ganha atratividade devido à sua tela com marcos estreitos. As entranhas estão em conformidade com as últimas tendências do setor. Um processador quad-core Whiskey Lake fornece energia computacional suficiente para aplicativos de Office e de Internet. No entanto, todo o seu potencial só pode ser desbloqueado no modo de CA. No modo bateria, a CPU mal usa seu turbo, se é que chega a fazê-lo. Esse é o preço que você paga pela boa duração da bateria.

Com o Latitude 7400, a Dell fornece um portátil comercial de gama alta que não está isento de fraquezas.

Um veloz SSD NVMe garante um sistema ágil. É possível substituir o SSD No entanto, para isso, a carcaça teria que ser aberta. Um destaque do portátil, em nossa opinião, é o teclado. Este é um dos melhores teclados que vimos até agora. Obviamente, uma iluminação por tecla (dois níveis) está a bordo.

a tela IPS mate ganha pontos com ângulos de visão estáveis, bom contraste, uma representação de cores decente de fábrica e uma boa cobertura do espaço de cores. O brilho da tela é bom, mas deveria ser melhor para um portátil nessa faixa de preço. Assim, o portátil não pode realmente ser usado em exteriores.

A porta Thunderbolt 3 permite a conexão de soluções docking e/ou uma GPU externa poderosa. Obviamente, a porta suporta Power Delivery 3.0 e DisplayPort sobre USB-C (isso requer um adaptador separado). Infelizmente, o ventilador emite um assobio.
