Breve Análise do Conversível Ematic EWT117 (Atom x5-Z8350)

Allen Ngo, 👁 Allen Ngo (traduzido por Ricardo Soto), 04/06/2019

Boa tela, mas muito lenta O Ematic de 11,6 polegadas oferece muito no papel, mas não tem a velocidade de acompanhar até mesmo as mais simples tarefas, como navegação, streaming de 1080p ou até mesmo processamento de texto. Você estará melhor investindo esses $200 em outro lugar.

Display Response Times

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
29.6 ms ... rise ↗ and fall ↘ combined↗ 18.4 ms rise
↘ 11.2 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 0.8 (minimum) to 240 (maximum) ms. » 71 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
38.4 ms ... rise ↗ and fall ↘ combined↗ 19.6 ms rise
↘ 18.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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 500 Hz ≤ 25 % brightness setting

The display backlight flickers at 500 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 25 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 500 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9361 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Ematic EWT117BL. Test model provided by Ematic

O EWT117 da Ematic é um exemplo clássico de prometer muito por pouco dinheiro. Um portátil conversível Windows 10 totalmente funcional com leitor MicroSD, porta HDMI e tela táctil IPS de 1080p por menos de $180 dólares ainda é bom demais para ser verdade, sem grandes inconvenientes. Nesse caso, o sistema é extraordinariamente lento devido à CPU Atom e ao desempenho muito ruim do SSD. Até mesmo ações simples como processamento de texto ou reprodução de vídeo - nas quais a Ematic deve se destacar - movem-se a passo de caracol.

Nossa unidade também apresentou alguns problemas de hardware. O trackpad frequentemente fazia com que o cursor do mouse pulasse inesperadamente e nosso cartão MicroSD às vezes ficava preso no mecanismo com mola do leitor MicroSD.

O melhor aspecto do Ematic é sua tela táctil IPS de 1080p, que abrange uma gama surpreendentemente ampla de cores (95% sRGB), considerando o preço. Infelizmente, isso significa pouco dado que o resto do sistema é inferior.

Nós não estamos pedindo muito de um netbook táctil de $ 200. No entanto, quando até mesmo um tablet Android de $200 de orçamento pode navegar, digitar e reproduzir vídeos mais rapidamente do que a Ematic, torna-se difícil recomendar o EWT117 para a maioria dos usuários domésticos.
