MagyarBreve Análise do Portátil Microsoft Surface Book 2 (15", i7, GTX 1060)
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 21930 Hz | ≤ 50 % brightness setting |  |
The display backlight flickers at 21930 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 21930 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Após as primeiras horas com o novo Surface Book 2 15, conseguimos desenhar muitos paralelos entre ele e seu irmão menor. O novo controle deslizante de desempenho no Windows 10, mais uma vez, tem bastante impacto no ruído do ventilador. O processador no tablet resfriado de forma ativa. No entanto, esperávamos mais da solução de resfriamento melhorada (em comparação com o modelo de 13 polegadas).
A tela é mais brilhante, mas tem mais problemas com bleeding de tela e utiliza PWM para o controle de brilho. Além disso, a calibração da fábrica não é muito boa. De acordo com nossos primeiros testes, a bateria maior faz um bom trabalho para compensar o aumento do consumo de energia do painel maior e, ao navegar na web, você pode esperar mais de dez horas de duração da bateria.
Vamos realizar os testes e benchmarks restantes nos próximos dias. Ao fazê-lo, nos concentraremos principalmente nos impactos no desempenho e no consumo de energia dos vários perfis de energia.
