Bernie Pechlaner (traduzido por Ricardo Soto), 04/11/2017

Empresarial como é habitual. Com o seu chassi redesenhado, peso mais leve e duração de bateria muito melhorada, o Latitude de gama superior, mais uma vez marca todas as caixas de verificação corretas quando se trata de portáteis empresariais. O 7480 de 14 polegadas está equipado com hardware atual, oferece ótimo desempenho e possui um teclado de primeira categoria. No entanto o barulho da bobina é muito perceptível.

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↗ 18.8 ms rise
↘ 12.4 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. » 78 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.9 ms).
       Response Time 50% Grey to 80% Grey
40.8 ms ... rise ↗ and fall ↘ combined↗ 19.2 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. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (43 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: 58 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 5559 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Dell Latitude 7480. Test model provided by Dell US

Embora não chegue perto do glamour dos seus irmãos XPS de 13 e 15 polegadas da própria Dell, o Latitude 7480 é de certa forma  o equivalente empresarial daquelas máquinas mainstream bem recebidas. O portátil de 14-polegadas de bom visual é menor e muito mais leve que antes, mas a qualidade de construção continua sendo inquestionavelmente alta. O chassi é sólido com tolerâncias apertadas e possui um acabamento suave e amigável ao toque. A tela é brilhante com cores precisas e revestimento antirefletivo, portanto, os viajantes não terão que lidar com reflexos irritantes. O desempenho é de primeira categoria - embora os testes específicos da CPU fiquem um pouco para trás, o portátil se destaca quando se trata de benchmarks sintéticos - e a bateria dura todo o dia mesmo sem ser completamente carregada. Os dispositivos de entrada também são muito bons com o teclado em particular, recebendo o nosso assentimento como um dos melhores disponíveis no mercado atualmente.

O Latitude 7480 é um portátil empresarial sólido de alta qualidade. No entanto, o barulho de sua bobina poderia ser um fator decisivo para alguns.

Se houver uma pontos negativo flagrante, é o barulho da bobina, que é audível há pelo menos 3 metros de distância e parece estar presente independentemente do nível de uso (mas é claro, mais perceptível durante o modo inativo). Certamente esperamos que este barulho afete apenas o nosso modelo de teste, mas dado que observamos o mesmo tipo de barulho durante nossa análise do Latitude 5480 e 7280, não ficaríamos surpresos se este for um problema mais espalhado.
