Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 21000 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 21000 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 21000 Hz is quite high, so most users sensitive to PWM should not notice any flickering. 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. | |||

A HP oferece uma atualização de geração cultivada para os compradores do EliteBook 755 G5. O desempenho da CPU AMD Ryzen 7-2700U é bom, mas poderia ter sido ainda melhor com um resfriamento otimizado. A tampa inferior removível oferece aos usuários acesso ao interior, permitindo que eles executem tarefas de manutenção. A boa cobertura do espaço de cores é levemente diminuída pelo alto valor de preto e baixo contraste.
O HP EliteBook 755 G5 é um atraente portátil empresarial com desempenho suficiente também para tarefas mais exigentes e uma duração de bateria que dura um dia inteiro de trabalho.
Os usuários recebem um dispositivo que é apresentável com seu design atraente e oferece duração de bateria suficiente para um dia útil. O fato de que o consumo de energia é maior do que em outros dispositivos não tem consequências graves e, além disso, dificilmente há razões que falem contra a compra do HP EliteBook 755 G5.
