Breve Análise do Portátil HP ProBook 640 G2

Name: HP ProBook 640 G2-T9X60ET
Brand: HP

Reiteração bem-sucedida. Dispositivos de entrada de alta qualidade, um painel Full HD, longa duração da bateria - parece que a HP montou um pacote de escritório convincente com o seu ProBook 640 G2. Infelizmente, algumas fraquezas nos detalhes estragam a boa impressão geral.

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
24 ms ... rise ↗ and fall ↘ combined	↗ 17.6 ms rise
24 ms ... rise ↗ and fall ↘ combined	↘ 6.4 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. » 50 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
43.2 ms ... rise ↗ and fall ↘ combined	↗ 21.6 ms rise
43.2 ms ... rise ↗ and fall ↘ combined	↘ 21.6 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. » 69 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 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 detected

200 Hz

≤ 90 % brightness setting

The display backlight flickers at 200 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 200 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.

In review: HP ProBook 640 G2. Test model courtesy of Notebooksbilliger.de

Embora existam alguns portáteis de escritório mais elegantes e finos que o ProBook 640 G2, a HP sem dúvida montou um pacote interessante no que diz respeito as outras qualidades do aparelho de 14-polegadas. Apenas alguns rivais podem oferecer uma unidade ótica e uma saída VGA. Isto, no entanto, cobra o seu preço no peso. Em troca, o ProBook compensa por isso com dispositivos de entrada impecáveis, alto desempenho de aplicativos, e longa duração da bateria. O fabricante também tem que ser aplaudido pelo módulo LTE integrado e baixas emissões.

Infelizmente, algumas fraquezas nos detalhes estragam a bora impressão deixada até esse ponto. Primeiramente por causa do layout desfavorável das interfaces, a ventoinha pulsante, e a tela TN extremamente dependentes dos ângulos de visão. Particularmente, este último é decepcionante em vista do preço de quatro dígitos e também porque todos os concorrentes (pelo menos opcionalmente) oferecem painéis IPS de maior qualidade. O brilho máximo especialmente alto somente compensa até certo grau. Os compradores que possam ignorar estas desvantagens podem optar pelo portátil - depois de tudo, os aparelhos da Dell, Lenovo ou Toshiba também têm críticas.

Os compradores que possam ignorar a tela dependente dos ângulos de visão e construção robusta encontrarão um sólido aparelho de trabalho para o escritório no ProBook 640 G2, que comparado com a concorrência, também vem com um singular destaque na forma de unidade ótica.
