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↗ 16.4 ms rise
↘ 14 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 (25.7 ms).
       Response Time 50% Grey to 80% Grey
48.8 ms ... rise ↗ and fall ↘ combined↗ 23.6 ms rise
↘ 25.2 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. » 82 % of all devices are better.
This means that the measured response time is worse 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 not detected

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.

O Latitude 7390 2-em-1 é uma máquina robusta, atraente e bem construída, com dispositivos de entrada muito bons e desempenho geral rápido do sistema. Ele também possui ótimas opções de conectividade, fácil manutenção e um formato menor do que a média para sua classe. Particularmente impressionante é a opção de armazenamento duplo, possibilitada pelo slot WWAN vazio, que também pode acomodar um SSD M.2/NVMe 2230. No entanto, embora o desempenho da CPU ainda seja um pouco mais rápido do que as máquinas comparáveis da geração anterior, vemos pouca justificativa para a configuração do Core i7 que recebemos como uma unidade de teste. Em vez disso, a menos que os aplicativos single-threaded sejam os únicos itens da pauta, sugerimos que você use uma configuração mais econômica do Core i5.

O Latitude 7390 2-em-1 é uma máquina robusta, atraente e bem construída, com dispositivos de entrada muito bons e desempenho geral rápido do sistema. No entanto, ele tem sua parte de desvantagens e, certamente, não é um investimento pequeno. Por isso, antes de mergulhar, recomendamos que você pesquise a paisagem.

Em outros lugares, o 7390 2-em-1 também é atrapalhado por alguns outros pontos de interrogação. Apenas telas tácteis refletivas estão disponíveis para configuração e nenhuma delas é particularmente impressionante no âmbito da cobertura de cores - pelo menos, não em comparação com os líderes de categoria, como o ThinkPad X1 Carbon. O SSD NVMe que recebemos em nossa unidade dificilmente poderia acompanhar as unidades de primeira linha, como os da Samsung. A máquina é bastante pesada para seu tamanho e, graças à sua tampa de tela mais grossa e comparativamente mais pesada, ela não parece ser tão estável no colo como gostaríamos. E, por fim, há sempre a questão de saber se a maioria das pessoas na empresa realmente precisa da funcionalidade conversível fornecida por estes derivados do estilo Yoga. A Dell já tem uma oferta perfeitamente capaz e extremamente equilibrada no fantástico Latitude 7380 (e, embora ainda tenhamos que analisá-lo, presumimos que também o 7390) - e pode ser equipado com uma tela anti-refletiva, é mais leve e parece mais estável em qualquer superfície.

Outras máquinas que vale a pena considerar (além do convencional Latitude 7380/7390) são o excelente ThinkPad X1 Carbon 2018 e Asus Zenbook 13 UX331UA. Com um preço de $2.109 (conforme configurado) o 2-em-1 Latitude 7390, certamente, não é um investimento pequeno. Por isso, antes de mergulhar, recomendamos que você pesquise a paisagem.
