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 | ||
|---|---|---|
| 30 ms ... rise ↗ and fall ↘ combined | ↗ 15 ms rise |  |
| ↘ 15 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 78 % 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 | ||

| 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. » 86 % of all devices are better. This means that the measured response time is worse than 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 not detected |  | ||
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 Acer Swift 7 SF714 é um subportátil ultracompacto que é bem adequado para uso móvel. O Swift 7 melhora ligeiramente o seu antecessor em todas as áreas; a maior diferença é a maior tela multi-touch de 14 polegadas. A Acer também revisou o chassi para tornar o novo Swift 7 ainda mais fino do que seu antecessor. Infelizmente, isso compromete a estabilidade.
A Acer manteve a seleção limitada de portas com o seu mais recente Swift 7, mas agradecemos a inclusão de um modem LTE. Desejamos apenas que a Acer tenha incluído um leitor de cartões de memória, pois isso aumentaria a flexibilidade do dispositivo.
Elogiamos muito os acessórios incluídos. A capa tem uma sensação premium e é bem feita. Isso também se aplica ao hub USB Type-C, que expande a seleção de portas do Swift 7 para uma porta USB tipo A e uma única porta HDMI.
O Acer Swift 7 SF714 melhora o seu antecessor em todas as áreas, particularmente com sua tela multi-touch maior. O preço também mudou, ou seja, subiu. No entanto, a Acer esqueceu um truque a este respeito?
Uma grande crítica ao Swift 7 é seu preço. O Acer Swift 7 SF714 custa uns impressionantes 1.699 Euros (~$1.973), o que é uma relação de preço-desempenho significativamente mais baixa do que com o seu antecessor. Em última análise, os potenciais compradores devem decidir por si mesmos se as inovações e o desempenho levemente aumentado justificam esse aumento acentuado no preço.
Não podemos dar ao Acer Swift 7 SF714 uma recomendação de compra clara apenas devido ao seu elevado preço avulso.
Outra queixa menor que temos é com o touchpad. A ausência de um mecanismo de clique torna o uso do dispositivo muito mais difícil no uso diário.
No geral, o Acer Swift 7 SF714 é um dispositivo inteligente e ultra móvel com uma duração de bateria impressionante que é manchado pelo seu preço elevado.
