Breve Análise do Portátil Acer TravelMate P249-M-5452 (Core i5, Full HD)

Companheiro empresarial de nível de entrada. Este modelo da Acer de 14-polegadas tem muito a oferecer: opções de atualização simples, boa duração da bateria, SSD veloz e um teclado confiável. A tela é o único ponto fraco deste pacote: um painel TN com ângulos de visão pobres.

Screen Flickering / PWM (Pulse-Width Modulation)

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 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.

Display Response Times

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
16 ms ... rise ↗ and fall ↘ combined↗ 10 ms rise
↘ 6 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 33 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 23 ms rise
↘ 21 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 71 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.9 ms).

In review: Acer TravelMate P249-M-5452. Test model provided by Acer Germany.

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.
