Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 50 Hz | ≤ 10 % brightness setting | |
The display backlight flickers at 50 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 50 Hz is very low, so the flickering may cause eyestrain and headaches after extended use. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured. |

A Acer deseja servir a usuários empresariais de nível de entrada com o TravelMate P249-M. O grupo de usuários inclui empresas, freelancers e estudantes. Típicos recursos empresariais como um leitor de digitais, porta docking ou modem LTE, não estão incluídos. O processador fornece suficiente desempenho para tarefas do dia a dia e o portátil funciona de forma silenciosa e quase não esquenta. Um SSD veloz garante que o sistema funcione fluentemente. Substituir o SSD via a escotilha de manutenção não é um problema. A duração da bateria e os dispositivos de entrada também são bons. O fabricante completa o pacote com uma garantia de três anos. Somente podemos criticar a tela, dado que a Acer escolheu um painel TN, que oferece bom contraste, mas ângulos de visão e brilho pobres.
O Acer TravelMate P249-M é um aparelho de trabalho confiável, que merece uma tela melhor.
Nosso modelo de teste é o modelo top desta série, dado que está equipado com uma tela FHD, CPU Core-i5 e SSD. Se você preferir preços mais baixos, confira a configuração de nível de entrada (P249-M-3895). O preço para os modelos mais econômicos está em cerca de 560-580 Euros (~$618-~$639). Vamos publicar uma análise desta configuração em um futuro próximo na Notebookcheck.com.
Se você não gosta do visual do P249-M, nós recomendamos dar uma olhada no Acer TravelMate X349-M, que é uma opção mais elegante. O X349-M está equipado com uma carcaça e de alumínio fina, um painel IPS (P249-M: TN LED), um sensor de digitais e um slot USB Type-C. O P249-M oferece um teclado melhore opções de atualização.
