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
32 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 15.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 82 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
41.6 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 19.6 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. » 53 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41 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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8773 (minimum: 43 - maximum: 142900) Hz was measured.

The Dell Latitude 7490
The Dell Latitude 7490

Mais uma vez, uma máquina da série Dell Latitude 7000 nos deixa completamente impressionados. Juntamente com os ThinkPads da Lenovo e os EliteBooks da HP, os Latitudes sobressaem do resto da concorrência empresarial. Eles são cuidadosamente projetados, atualizados com inteligência e revisados com cuidado. Enquanto o 7490 é uma mera atualização iterativa do 7480 em todos os sentidos, realmente deixa pouco a desejar. A carcaça é robusta, discreta e atraente, o peso é aceitável, os dispositivos de entrada são excelentes, o desempenho é muito bom, a duração da bateria é longa e é um companheiro silencioso. As poucas áreas de melhoria que gostaríamos de ver são opções de tela para igualar seus concorrentes, melhor gerenciamento térmico e melhores alto-falantes.

Mais uma vez, uma máquina da série Dell Latitude 7000 nos deixa completamente impressionados. O Latitude 7490 de $1.709 hoje, é absolutamente digno de consideração por qualquer pessoa no mercado em busca de um portátil corporativo premium.

A configuração menos cara de hoje não tem o Core i7, o armazenamento NVMe, a tela sensível ao toque e alguns dos recursos biométricos e de segurança da unidade de teste de abril, mas também é de apenas $1.709 (comparado os $2.000 do modelo anterior). Aqueles que não precisam de memória dual-channel ou de qualquer das omissões listadas anteriormente, não encontram muito do que reclamar nesta configuração. Junto com o X1 CarbonT480sHP EliteBook 840 G1, e Latitude 7390, o Latitude 7490 merece consideração por qualquer pessoa no mercado à procura de um portátil corporativo premium.
