Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 219.3 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 219.3 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 219.3 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 8746 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Verdict
Com uma construção bem leve que é portável e durável (graças à construção híbrida de gama alta de fibra de carbono e magnésio), excelente duração da bateria, e excelentes dispositivos de entrada pelos quais a marca ThinkPad é conhecida há muito tempo, o Lenovo ThinkPad T470s FHD já deve ter a atenção de profissionais empresariais à procura de seu próximo companheiro do dia a dia. Mas adicione a isso o excelente desempenho dos aplicativos (possível ´graças a um muito veloz SSD NVMe SSD da Samsumg), sólido desempenho da CPU do chip Core i5, e fácil manutenção, e este é um dispositivo difícil de recusar.
Pontos negativos? Sim, há alguns. Para começar, a tela não é tão impressionante quanto as de muitos concorrentes, e dá um passo para trás do modelo WQHD não apenas em termos de resolução, mas também no brilho, contraste, e reprodução de cores. Detectamos PWM em todos os níveis de brilho, exceto no máximo, o qual é uma decepção para um ThinkPad. E finalmente, o aparelho esquenta rapidamente, atingindo rápido temperaturas perturbantes na carcaça (sob carga), especialmente durante o uso sobre as pernas.
Fora o desafortunado flicker PWM, qualidade baixa da tela, e um pouco de calor desagradável durante cargas de trabalho mais pesadas, o Lenovo ThinkPad T470s FHD é uma excelente escolha.
Se o usuário não se importar com uma duração da bateria ligeiramente inferior (mas ainda muito boa) e um preço mais alto, recomendamos que dê uma olhada no modelo T470s WQHD que analisamos recentemente, dado que sua tela não apenas oferece melhores brilho e cores, mas também não utiliza PWM para controlar as reduções do brilho. No entanto, a CPU Core i5 que analisamos na configuração atual parece ser um investimento mais racional, considerando o excelente desempenho e a relativa estabilidade, contra o i7 da configuração WQHD que avaliamos. O Dell Latitude 7480 também é uma ótima opção — ou, se o orçamento permite, o ThinkPad X1 Carbon. Mas, além dos problemas da tela, desde que o usuário não se importe com um pouco de calor durante as o uso mais pesado, o T470s FHD é um concorrente imediato para um dos melhores portáteis de negócios de 14 polegadas no mercado, hoje em dia.
