Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 500 Hz | ≤ 25 % brightness setting |  |
The display backlight flickers at 500 Hz (worst case, e.g., 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8734 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
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.
