Breve Análise do Conversível Dell Inspiron 17 7778

Name: Dell Inspiron 17 7778
Brand: Dell

Conversível gigante. Um conversível de 17 polegadas? Por quê não? Quem queira que prefira o uso estacionário do Windows 10 no modo tablet deve estar absolutamente contente com esta combinação um pouco incomum. No entanto, o Inspiron também faz um bom trabalho com uma máquina de escritório convencional - somente o teclado poderia ter sido de maior qualidade para este preço.

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
22 ms ... rise ↗ and fall ↘ combined	↗ 5 ms rise
22 ms ... rise ↗ and fall ↘ combined	↘ 17 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 44 % of all devices are better. This means that the measured response time is similar to the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
36 ms ... rise ↗ and fall ↘ combined	↗ 14 ms rise
36 ms ... rise ↗ and fall ↘ combined	↘ 22 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. » 46 % 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 not detected

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: Dell Inspiron 17 7778. Test modelcourtesy of Dell Germany

O novo Inspiron 17 7778 2-em-1 da Dell, sem dúvida é um conversível um pouco exótico, cujos aspectos de mobilidade não serão tão importantes como nos conversíveis menores, devido unicamente ao seu tamanho e peso. Mas isso não é uma falha, dado que os modos adicionais típicos de um conversível são basicamente um bônus em um aparelho que pode ser utilizado perfeitamente como um portátil multimídia tradicional e inclusive permite jogar ocasionalmente, graças à GeForce 940MX. A carcaça é absolutamente convincente, e a tela também. O sistema normalmente roda muito de forma muito silenciosa. Muita duração sem a necessidade de uma tomada, agradará os usuários se estiverem de viagem com o 7778.

Além das dobradiças, que são irrelevantes em alguns modos, temos que criticar o teclado não ideal que provavelmente não satisfará os escritores mais prolíficos. A placa de vídeo que, às vezes, tende a se afogar, não é tão importante. O modelo de teste também tem que adicionar a tela táctil que não pode ser utilizada de forma ideal com dedos húmidos, se isso for evitável (via um acabamento?).

No geral, o Dell Inspiron 17 7778 é um conversível enorme bem concebido, flexível e elegante que tem apenas alguns compromissos para os fanáticos do uso híbrido.
