Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 352.1 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 352.1 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 352.1 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. 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
Verdict - Good, but there are better options
O Lenovo Flex 14 deixa uma impressão confusa. Suas áreas mais fortes estão na duração da bateria e na velocidade de armazenamento. É difícil encontrar um portátil com uma unidade NVMe no preço de US$800, e o fato de o Flex 14 durar o dia inteiro com uma carga é a cereja no topo do bolo. No entanto, o Flex 14 compromete o teclado, um corpo de plástico e uma tela medíocre.
O Flex 14 talvez seja mais adequado para estudantes em busca de um conversível de baixo custo que não se importe em sacrificar no teclado, qualidade de construção e brilho da tela. Existem opções semelhantes disponíveis a um preço mais baixo (como o Asus VivoBook Flip 14). Gastar um pouco mais pode render o superior Yoga 730 ou ThinkPad X390 Yoga, ambos os quais superam o Flex 14 em todas as áreas. O HP Envy x360 13 também é uma opção viável; por US$ 100 a 200 a mais, o Envy x360 garante uma tela mais brilhante, teclado melhor e melhor desempenho gráfico, apesar de sacrificar algumas horas de duração da bateria.
É difícil pegar o Flex 14. Embora não falhe em nenhuma categoria, ele também não se destaca em nenhuma. O Flex 14 é um tipo de portátil "poli funcional, mestre de nenhum" e não se destaca de nenhuma maneira significativa.
