| 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. » 55 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms). | ||

| 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. » 44 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (32.9 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 131000 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 131000 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 131000 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

O Ideapad 720s da Lenovo é um portátil muito leve e ultra fino para o trabalho de escritório rotineiro. Como um dos poucos dispositivos em nosso teste, o Ideapad 720s é capaz de manter seu desempenho de forma consistente e sem quedas. Mesmo em condições extremas, o bom resfriamento garante que o sistema possa continuar a ser utilizado. No entanto, as opções de manutenção são limitadas, e a Lenovo também se concentrou apenas nas conexões mais essenciais. Mas graças às conexões Thunderbolt, todas as portas necessárias podem ser fornecidas pelo periférico correspondente.
Com o Lenovo Ideapad 720, os compradores recebem um portátil muito fino e leve, que sempre estará lá, mas nunca no caminho durante a vida cotidiana.
Nas ofertas atuais, o Ideapad 720 pode ser comprado com uma CPU Kaby Lake da 8ª geração, sem hesitação. No entanto, os compradores devem seguir suas próprias preferências ao decidir se os modelos com os processadores Ryzen 5 2500U da AMD ou os processadores Kaby Lake da 7ª geração, valem a pena, em termos de preço.
