| The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 68 % of all devices are better.

| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 46 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.8 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 198.4 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 198.4 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 198.4 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 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
Os melhores aspectos do Miix 520 são o desempenho do processador, desempenho do SSD, versatilidade das portas e o preço. Seu desempenho por dólar é um dos melhores no mercado no momento, já que a maioria dos outros tablets Windows ainda conta com as opções Core Y ou de 7ma geração. Os usuários que podem explorar a potência adicional encontrarão o Miix 520 como uma adequada imitação de Ultrabook, adequado para viajar.
Tudo o resto sobre o Lenovo conversível não é necessariamente ruim ou mesmo médio, mas definitivamente há espaço para melhorar quando comparado a algumas alternativas próximas. O Surface Pro e Elite x2 são de design mais robusto, contam com telas de maior resolução e mais brilhantes, cores mais precisas e maior duração da bateria. O tablet HP, em particular, também traz o Thunderbolt 3 para uma gama ainda maior de opções de conectividade. Uma base de teclado mais firme para o Lenovo teria melhorado a experiência de digitação esponjosa em relação aos teclados na maioria dos Ultrabooks.
A desvantagem mais notável do desempenho do processador mais rápido é o ruído do ventilador. O ventilador é um pouco mais barulhento do que o Surface Pro e irá rodar muito mais freqüentemente durante o uso diário. Não é tão barulhento quanto a série de conversíveis Spectre da HP, mas é notável, no entanto, especialmente para um formato de tablet.
O Miix 520 é uma ótima compra, desde que os usuários estejam conscientes de suas desvantagens. O desempenho rápido da CPU vem ao custo de um ruído de ventilador mais alto e mais frequente. Esperamos que futuras revisões atualizem a tela e incorporem o Thunderbolt 3 para tornar a série Miix ainda mais competitiva contra a Microsoft.
