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
9 ms ... rise ↗ and fall ↘ combined↗ 6.8 ms rise
↘ 2.2 ms fall
The screen shows fast response rates in our tests and should be suited for gaming.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 6 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (25.7 ms).
       Response Time 50% Grey to 80% Grey
28.8 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 12.4 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 0.9 (minimum) to 636 (maximum) ms. » 13 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41.1 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 detected 25770 Hz ≤ 20 % brightness setting

The display backlight flickers at 25770 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 25770 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8801 (minimum: 43 - maximum: 142900) Hz was measured.

Defiance IV, test unit provided by PC Specialist

O Defiance IV parece ótimo. Sua carcaça é bem construída e discreta e possui superfícies metálicas de boa aparência que, apesar de atrair sujeira rapidamente, dão uma impressão sólida e de alta qualidade.

Como deveria ser para um portátil de jogos moderno, o dispositivo também possui um teclado retro iluminado. Se você esquecer da porta Thunderbolt 3 ausente, sua conectividade também é impressionante.

Há dois lados da tela de 120-Hz. Embora o grande espaço de cores e os tempos de resposta baixos sejam excelentes, eles não podem equilibrar completamente os ângulos de visão medíocres e o forte desvio de cores (de fábrica). O valor de preto, o brilho e sua distribuição, por outro lado, não deixam nada para criticar.

A velocidade da CPU é um pouco mais problemática. O fato de o processador se afogar abaixo de sua velocidade básica durante algumas aplicações 3D exigentes não é ideal para um portátil de jogos, mesmo que a queda na velocidade nem sempre seja perceptível no desempenho do dispositivo. Talvez o fabricante nos dê uma atualização do BIOS que resolva o problema. Se o Core i7-7700HQ conseguisse alcançar seu potencial pleno, os portáteis concorrentes de 17 polegadas (Acer V17 NitroMSI GS73VR 7RG, etc.) teriam que estar temerosos.

Além do bom tempo de duração da bateria, que é habilitado pelo recurso de comutação de gráficos Optimus da Nvidia, também queremos mencionar as emissões de primeira classe durante o modo inativo, a carcaça amigável com a manutenção e as opções de configuração individuais. No entanto, preferiríamos menos ruído do sistema e temperaturas mais baixas sob carga.
