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
30.4 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 11.6 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. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.1 ms).
       Response Time 50% Grey to 80% Grey
36.8 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise
↘ 18.8 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. » 30 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41.7 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: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 10415 (minimum: 43 - maximum: 588200) Hz was measured.

Contra

- Impossível de abrir com uma mão

- O leitor de impressões digitais parece mais exigente do que alguns modelos

Nossa lista de reclamações encolheu desde a análise do Latitude 7390 do mês passado, parcialmente graças a diferenças de configuração com a unidade de teste de hoje, e parcialmente apenas porque alguns desses itens podem ser um produto de idiossincrasias das próprias máquinas individuais. A atualização para um Core i7 certamente traz consigo algumas vantagens de desempenho - principalmente durante cargas sustentadas, onde as velocidades não são apenas melhores, mas também mais consistentes, no geral. No entanto, para a grande maioria dos usuários, o Core i5 é mais do que poderoso e a redução de custos pode torná-lo uma opção mais atraente. Grande parte da mesma lógica se aplica ao SSD NVMe (versus a opção convencional M.2 SATA que vimos na unidade de teste Latitude 7390 do mês passado) que é mais rápido, mas também gera mais calor e tem um preço maior. Mais surpreendentemente, no entanto, a tela táctil antirreflexo nesta configuração é verdadeiramente antirreflexo; não traz pontos negativos em comparação ao painel convencional (não táctil) do mês passado.

É certamente caro, mas há poucos outros portáteis em sua classe, tão impressionantes quanto o Latitude 7390.

A longa lista de pros ainda se aplica. O 7390 possui um acabamento impecável e uma construção robusta, ao mesmo tempo em que tem dimensões pequenas e é leve. A manutenção é fácil graças à tampa inferior removível. A seleção completa de portas e as opções de segurança robustas serão apreciadas pelos guerreiros da estrada empresariais e pelos departamentos de TI corporativos. O teclado e o touchpad, da unidade de teste atual, foram muito bons no geral e o painel da tela continua atraente, apesar das diferenças nos componentes introduzidos pela capacidade de toque. Finalmente, o dispositivo permanece em silêncio na maior parte do tempo, e os tempos de duração da bateria são longos. Acrescente uma garantia de 3 anos no local e você tem um concorrente muito forte dentro do segmento empresarial.

A $2.197, certamente é caro, mas há poucos outros portáteis em sua classe, tão impressionantes quanto o Latitude 7390. O Lenovo X1 Carbon e o HP EliteBook Folio 1040 G1 da HP, são provavelmente os principais concorrentes - mas seria difícil errar com qualquer uma dessas máquinas, honestamente.
