| 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. » 46 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.9 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 208 Hz | ≤ 10 % brightness setting |  |
The display backlight flickers at 208 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 10 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 208 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Pro
Contra
O dispositivo tem um design elegante, embora sua carcaça plástica tenha algumas inconsistências no acabamento. A Dell também equipou o Vostro 15-5581 com dispositivos de entrada decentes, então você nunca deveria sentir a necessidade de pegar um mouse ou teclado externo.
Infelizmente, a tela em nossa unidade de teste está abaixo do esperado, com um brilho máximo inaceitavelmente baixo. Ele tem ângulos de visão estáveis e um acabamento mate, então as reflexões de luzes artificiais brilhantes nunca deveriam ser um problema.
No lado positivo, o Vostro 15-5581 tem potência suficiente para lidar com todas as tarefas de escritório e até mesmo com tarefas gráficas mais intensas, graças à sua GPU GeForce MX130. No entanto, o dispositivo não obtém o máximo dos dois componentes, e seu comportamento é muito agressivo para o nosso gosto. No entanto, o Vostro 15-5581 fez avanços a partir de seu antecessor, com mais potência, melhores dispositivos de entrada e maior duração da bateria.
O Dell Vostro 15-5581 é um portátil de 15,6 polegadas mediano. Não irá inspirar as pessoas, mas não foi feito para isso. Simplesmente, vai fazer o trabalho.
No geral, o Vostro 15-5581 se destaca em algumas áreas, como a duração da bateria e o desempenho da CPU. Uma tela nada surpreendente, um ventilador agressivo e um SSD comparativamente lento, estragam o que poderia ter sido um sólido portátil corporativo.
