Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 1852 Hz | ≤ 98 % brightness setting |  |
The display backlight flickers at 1852 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 98 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 1852 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

De muitas maneiras, o 2-em-um Latitude 5290 é o Surface Pro para o mundo dos negócios. Tudo, desde sua aparência discreta, manutenção relativamente conveniente, opções de segurança robustas, operação silenciosa e seleção de portas acima da média se ajusta perfeitamente aos requisitos diários do escritório. Além de tudo isso, ainda colhemos os benefícios de uma construção de liga de magnésio extremamente robusta, uma tela extremamente brilhante e vívida, desempenho de CPU muito veloz e um bom teclado/touchpad (no acessório Teclado de Viagem de US $ 150, vendido separadamente). Finalmente, o Active Pen ($60) opcional da Dell satisfaz as demandas de um subconjunto exclusivo de usuários que precisam de uma entrada precisa da caneta ativa sensível à pressão da Wacom.
De muitas maneiras, o 2-em-1 Latitude 5290 é o Surface Pro para o mundo dos negócios; sua combinação cuidadosa de luxo de nível de consumidor e sensibilidade de nível empresarial contribuem a um conversível exclusivo que atende a um conjunto muito específico de requisitos.
Mas não há dispositivos perfeitos e o Latitude 5290 vem com sua parcela de compromissos notáveis. A principal delas é a duração da bateria, em que o Latitude cai drasticamente atrás de alguns concorrentes recentes que usam SoCs Kaby Lake. Ele também é sobrecarregado por altas temperaturas de operação (superficiais e internas) sob uso intenso, embora o calor tenha sido redistribuído um pouco para longe das bordas do dispositivo (onde as mãos normalmente descansariam). A garantia padrão é decepcionantemente curta para um dispositivo com um preço tão significativo. A falta de Thunderbolt provavelmente irritará alguns usuários que desejam soluções docking versáteis. E, finalmente, voltando ao preço alto mencionado: $1.932 para a configuração atual (que, para ser justo, inclui pelo menos a capa do Travel Keyboard e o Active Pen).
Os principais concorrentes continuam sendo o Latitude 5285 do ano passado (que, pelo menos oferece uma melhor duração de bateria que o 5290), o Microsoft Surface Pro 2017 (que é muito bom no geral, mas impossível de atualizar e manter desde uma perspectiva de hardware), o HP Elite x2 1012 G2 (que é um dispositivo muito completo, mas notavelmente mais difícil de manter), e o Lenovo ThinkPad X1 Tablet Gen 2 (que é um bom concorrente, mas prejudicado pelas restrições do resfriamento passivo e outros aborrecimentos, como o PWM). Todos esses dispositivos apresentam seus próprios conjuntos de pontos fortes e fracos, por isso, antes de decidir sobre um conversível empresarial, sugerimos fortemente que você analise todos eles. No entanto, desde que a funcionalidade 2-em-1 (e talvez as entradas da caneta sensível à pressão) seja uma necessidade absoluta, há poucos dispositivos que gerenciam um desempenho geral tão forte quanto o Latitude 5290.
