Breve Análise do Portátil HP ProBook 450 G4 Y8B60EA

Benjamin Herzig (traduzido por Ricardo Soto), 01/03/2017

Tela indigna. HP é um dos primeiros fabricantes em usar Kaby Lake e sua linha 400 ProBook no setor empresarial. Por que o modelo de 15,6 polegadas não é convincente apesar de suas boas propriedades pode ser lido em nosso relatório.

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
30 ms ... rise ↗ and fall ↘ combined↗ 10 ms rise
↘ 20 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 70 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (27.1 ms).
       Response Time 50% Grey to 80% Grey
51 ms ... rise ↗ and fall ↘ combined↗ 23 ms rise
↘ 28 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 82 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (43.7 ms).

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 Hz40 % brightness setting

The display backlight flickers at 50 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 40 % 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: 59 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 4396 (minimum: 43 - maximum: 142900) Hz was measured.

In review: HP ProBook 450 G4
In review: HP ProBook 450 G4

O ProBook 450 G4 é, de fato, um aparelho sólido A carcaça é boa e dificilmente apresenta fraquezas, o pousa palmas de metal se sente bem, e o aparelho oferece uma seleção de interfaces muito sólida que inclusive inclui o USB Type-C. Embora esta porta não seja capaz de nada a não ser USB, ela fornece segurança para o futuro. O processador oferece bom desempenho, o teclado é adequado para digitar, e o touchpad corresponde ao padrão do Precision. Finalmente, está a boa duração da bateria que é certamente atraente para trabalhar em movimento.

Infelizmente, isto não compensa a maior desvantagem do aparelho: A péssima tela. Isto poderia talvez ser justificado com um preço de 600 Euros (~$627), mas isto é simplesmente inaceitável com quase 1000 Euros (~$1045). Depois estão as outras desvantagens: O leitor de digitais é muito pouco viável e o processador esquenta muito durante o suo intenso. A HP deveria permitir que a ventoinha gire a uma velocidade um pouco mais alta aqui.

Uma pena: O fabricante estraga um pacote quase completo com uma tela que é simplesmente inapropriada para o preço.

O ProBook tem pouca concorrência  no setor empresarial, pelo menos em termos de processador. No entanto, isto mudará em breve: O ThinkPad E570 foi anunciado, e será um aparelho de comparação interessante com o seu painel IPS e GeForce 950M. Os outros concorrentes provavelmente seguirão no início de 2017.
