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 ms ... rise ↗ and fall ↘ combined | ↗ 20 ms rise |  |
| ↘ 17 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. » 95 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||

| 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. » 49 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 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 8715 (minimum: 5 - maximum: 343500) Hz was measured. | ||

Contra
- Não é possível abri-lo com uma só mão
- Garantia de apenas um ano do fabricante
- Resolução da tela e densidade de pixel muito baixas
- Nível de preto muito alto, contraste fraco
- Tela muito dependente dos ângulos de visão
- Reprodução pobre das cores
- Tela muito escura em exteriores
- Sistema de som pouco utilizável
Enquanto o Dell Latitude 15-3570 esteja em oferta, particularmente o membro de menor preço do trabalhador de escritório pode se dizer que tem uma razão de preço-desempenho muito boa. Um preço de entrada de 419 Euros (~$463 incluindo o desconto) não é um problema para a boa carcaça e os bons dispositivos de entrada do modelo menor. No entanto, o modelo de teste exibe fraquezas evidentes na tela e no som, e por isso, os fanáticos da multimídia deveriam procurar outra coisa. Por outro lado, os aspectos técnicos, e a operação quase silenciosa e fria é impressionante. Se a bateria protuberante for um problema, também está disponível uma bateria de 48 Wh. Os usuários preocupados com a segurança receberão muito bem o chio TPM e a opção de leitor de digitais.
A versão testada do 3570 teve a vantagem de um manuseio bastante mais fluente que seus rivais graças ao seu SSD. No entanto, a tela não mantém o nível aqui, e nãos apenas por causa de sua baixa resolução.
