| The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 62 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||

| 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. » 51 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 133.3 Hz | ≤ 95 % brightness setting |  |
The display backlight flickers at 133.3 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 95 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 133.3 Hz is very low, so the flickering may cause eyestrain and headaches after extended use. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

O Guru Mars K é a escolha certa se você estiver procurando um substituto de desktop poderoso com excelente capacidade de manutenção/atualização e se o chassi volumoso e pesado não for um problema.
O portátil de jogos de 17 polegadas está cheio de hardware de gama alta. Uma combinação de Core i7-7700, GeForce GTX 1080, e SSD PCIe lida com qualquer aplicativo convencional com facilidade. Você também recebe bons dispositivos de entrada (teclado de três zonas com iluminação RGB!), sistema de som poderoso e muitas portas.
A tela IPS também é convincente, pelo menos se você pode viver com a resolução e a frequência (apenas 1080p @75 Hz). Não encontramos problemas com os ângulos de visão, precisão de cores, luminância ou contraste.
Os inconvenientes incluem o enorme consumo de energia e a limitada duração da bateria, mas estes não são pontos tão negativos para um substituto de desktop. O controle da ventoinha e o alto ruído do sistema sob as cargas de trabalho 3D são muito mais irritantes.
O Mars K ainda assegurará uma boa posição em nossa próxima atualização do Ranking dos Top 10.
