Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 50 Hz | ≤ 40 % brightness setting | |
The display backlight flickers at 50 Hz (worst case, e.g., 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: 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. |

Contra
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.
