Breve Análise do Portátil LG Gram 17Z990 (i7-8565U. WQXGA)

Allen Ngo, 👁 Allen Ngo (traduzido por Ricardo Soto), 04/22/2019

Quase tão leve quanto o XPS 13. O Gram 17 abala a tendência que os portáteis de 17 polegadas devem ser grandes e desajeitados. Com apenas 1,34 kg, o portátil é visivelmente mais leve do que a maioria dos Ultrabooks de 14 e 15 polegadas, oferecendo muitos dos mesmos recursos, incluindo o Thunderbolt 3 e uma bateria de longa duração.

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
31.2 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 13.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 80 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.1 ms).
       Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined↗ 20.4 ms rise
↘ 21.6 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. » 54 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (40.1 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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9461 (minimum: 43 - maximum: 142900) Hz was measured.

In review: LG Gram 17990-R.AAS7U1
In review: LG Gram 17990-R.AAS7U1

O LG Gram 17 é melhor para os usuários que desejam uma tela grande de 17 polegadas, mas que se desanimam pelas suas dimensões normalmente incômodas. É extraordinariamente leve e resistente para torná-lo um dos melhores portáteis em sua categoria de tamanho para os viajantes. Se você acha que a maioria dos Ultrabooks não oferece espaço suficiente na tela, então o Gram 17 deve estar na sua lista.

O preço a pagar por um portátil tão leve de 17 polegadas será alto. Apesar de sua composição em liga de metal e especificações MIL-STD 810G, o Gram 17 está longe de ser tão rígido quanto o XPS 15, o Spectre x360 15, ou mesmo a maioria dos outros Ultrabooks. Os proprietários terão que ter cuidado para não danificar a tampa frágil durante as viagens.

Outras desvantagens notáveis incluem as teclas e o clickpad suaves, a capacidade de manutenção não amigável para o usuário, a qualidade média de áudio e o desempenho do Core i7 abaixo da média. A LG poderia ter reduzido o preço de entrada, incluindo uma opção Core i5 e um SSD menor, sem afetar o desempenho geral do sistema. Por $ 1.500 USD, os usuários podem comprar um sistema mais robusto e significativamente mais rápido Dell XPS 15 para fazer que o Gram 17 pareça atraente. Se a grande tela 17 polegadas não lhe agradar, então poderia estar melhor com um Ultrabook tradicional e 13 ou 15 polegadas.

Muito mais leve do que outros Ultrabooks menores no mercado, oferecendo uma tela WQXGA de 17 polegadas. A LG criou um nicho confortável no relativamente impopular espaço de portáteis de 17 polegadas. O Gram 17 é uma solução multimídia e de escritório leve, ideal para viajantes que desejam explorar a espaçosa tela de 17 polegadas.
