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
38 ms ... rise ↗ and fall ↘ combined↗ 22.8 ms rise
↘ 15.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 95 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.1 ms).
       Response Time 50% Grey to 80% Grey
56 ms ... rise ↗ and fall ↘ combined↗ 31.6 ms rise
↘ 24.4 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 91 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (40 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 detected 1667 Hz ≤ 24 % brightness setting

The display backlight flickers at 1667 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 24 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 1667 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9448 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Dell Latitude 7400 2-in-1. Test model provided by Dell US

O Dell Latitude 7400 2-em-1 ($2.800 como testado) representa um passo importante em direção a uma filosofia de design diferente para os portáteis empresariais conversíveis do fabricante. Vamos começar com os prós e contras: sem dúvida, este é o Latitude mais atraente até hoje, com seu belo revestimento de alumínio escovado, bordas e cantos habilmente chanfrados por CNC e marcos super finos. Pode ser facilmente confundido com algo fora da linha de máquinas XPS.

Mas ao longo de sua transição, o Latitude procura reter muitas das sensibilidades práticas empresariais que há muito são cruciais para o sucesso da marca: manutenção fácil, construção durável, longos tempos de duração de bateria, operação silenciosa e dispositivos de entrada premium. A seleção de portas foi um sucesso com a adoção de portas de carregamento USB Tipo-C/ThunderBolt 3 e a omissão da porta Ethernet, mas em geral o usuário médio de negócios terá mais do que precisa à sua disposição para trabalhar. O áudio foi amplamente melhorado em relação às máquinas Latitude anteriores. E, finalmente, os tempos de duração da bateria em nossa unidade de teste com 78 Wh são excelentes, durando facilmente um dia inteiro de trabalho sem a necessidade de ter um carregador na mão.

O Latitude 7400 2-in-1 é uma revisão ambiciosa dentro de um mercado em que as filosofias padrão são tipicamente conservadoras e incrementais. De certa forma, é uma aspirada de ar fresco (quente!), mas não sem problemas.

No entanto, embora seja agradável ao toque e esteticamente, os resultados estão longe de ser universalmente positivos neste caso. A tela, apesar de atraente em interiores, sofre com um brilho fraco e é altamente reflexiva, tornando desconfortável o uso em exteriores e, em muitos casos, simplesmente implausível. Enquanto a transição para um touchpad de vidro é agradável, alguns usuários corporativos irão lamentar a mudança de botões físicos separados para um design de “clickpad” integrado. A RAM do sistema agora está totalmente soldada na placa-mãe, significando que atualizações e substituições são impossíveis (embora o SSD M.2 NVMe ainda possa ser substituído).

Mas a deficiência mais gritante de todas é a tendência das altas temperaturas do chip, que rapidamente sobrecarrega o sistema de resfriamento inferior e resulta em pontos quentes superficiais na carcaça e reduções de desempenho excessivas da CPU (e afogamento sob usos mais intensivos). Isso resulta em um desempenho que fica aquém dos modelos concorrentes mais baratos e menos equipados, mesmo de última geração, e questiona a praticidade de colocar um SoC Whisky Lake quente e faminto do Core i7 em uma carcaça tão pequena com um resfriamento conservador e insuficiente.

Estaríamos dispostos em trocar mais ruído do ventilador por melhor desempenho sustentado e temperaturas baixas, e felizmente isso pode ser parcialmente alcançado através de um switch para o perfil térmico Ultra Performance dentro do Dell Power Manager - que resulta em um desempenho sustentado pelo menos marginalmente melhor em nosso teste de loop Cinebench R15 (esperançosamente, uma futura atualização de firmware poderia melhorar  isto, o que o usuário médio não informado provavelmente não saberia como fazer). Independentemente disso, no entanto, achamos que faz mais sentido economizar seu dinheiro e investir em uma configuração com uma CPU Core i5 menos dispendiosa, onde as temperaturas certamente serão mais baixas e você não pagará pelos aumentos de desempenho que são marginais na melhor das hipóteses.

Os concorrentes mais bem classificados incluem o HP EliteBook x360 1040 G5 e o Lenovo ThinkPad X1 Yoga. O Asus Zenbook Flip 14 também está disponível, mas não se saiu tão bem quanto as duas máquinas anteriores em nossos testes. Como alternativa, pode valer a pena esperar um pouco para ver se e como a Dell revisa o firmware no 7400 2-em-1 para resolver esses problemas. É uma excelente máquina de várias maneiras - um pouco ambiciosa demais para o sistema de resfriamento.
