Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White
28 ms ... rise ↗ and fall ↘ combined	↗ 14.8 ms rise
28 ms ... rise ↗ and fall ↘ combined	↘ 13.2 ms fall
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. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
35.6 ms ... rise ↗ and fall ↘ combined	↗ 17.2 ms rise
35.6 ms ... rise ↗ and fall ↘ combined	↘ 18.4 ms fall
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. » 45 % 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)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

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 8746 (minimum: 5 - maximum: 343500) Hz was measured.

In review: Lenovo Miix 520 81CG00NBUS. Test model provided by Lenovo US

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.
