Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 27000 Hz | ≤ 90 % brightness setting | |
The display backlight flickers at 27000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 27000 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. |

O Acer Extensa 2540-580K possui uma CPU poderosa, um SSD rápido e uma RAM habilitada para canal duplo. O aparelho não esquenta sob qualquer tipo de carga e opera quase silenciosamente. Portanto, o Extensa oferece recursos e atributos associados à maioria dos portáteis de escritório.
Com o Extensa 2540, a Acer oferece um aparelho de escritório muito durável que terá que encontrar seu público. A tela será um grande impedimento para muitos compradores potenciais.
Felizmente, a Acer equipou o portátil com uma pequena escotilha de manutenção, atrás da qual o SSD e a RAM estão localizados. Portanto, substituir ou atualizar esses componentes não deve apresentar nenhum problema. O teclado, em geral, deixou uma impressão "boa". No entanto, gostaríamos muito de ter visto uma luz de fundo aqui. Com isso, a Acer poderia ter completado o aparelho de escritório, que é o que o Extensa deveria ser. A excelente duração da bateria adiciona mais valor ao portátil.
O ponto mais fraco do aparelho - como é frequente - é a tela. A Acer usa um painel escuro com contraste e ângulos de visão fracos aqui, o que não teria sido apropriado mesmo em um portátil de 400 euros (~$470).
Com este modelo, a Acer vai atrás de, principalmente, usuários profissionais, por isso a cópia pré-instalada do Windows 10 Pro. A versão profissional aumenta um pouco o preço do aparelho, o que torna o portátil bastante pouco atrativo aos usuários ocasionais. A Acer não oferece uma versão alternativa equipada de forma similar com o Windows 10 Home. O Extensa 2540-56GC é o mais próximo do nosso aparelho de teste. No entanto, somente vem com uma tela HD (1366x768).
Atualização 13/12/2017: A Acer nos informou que o modelo que testamos na nossa análise não está mais disponível e que foi substituído pelo modelo Extensa 2540-54C0, construído de forma idêntica.
