Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 531 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 531 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 531 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Escolher um conversível empresarial não é fácil. Depois de tudo o ThinkPad Yoga 370 e o EliteBook x360 são duas boas alternativas. Com o Latitude 5289, a Dell contribuiu com um concorrente interessante. A maior vantagem da unidade de teste: sua duração de bateria. Graças ao baixo consumo de energia e a uma bateria muito grande, o Latitude é o melhor aparelho nesta área. A carcaça robusta e o confortável teclado também merecem ser considerados. A ventoinha de resfriamento do Latitude 5289 permanece em silêncio graças à sua CPU ULV. A seleção das portas é adequada para um aparelho empresarial, o que nos leva para os aspectos negativos.
Um aparelho claramente acima da marca dos $ 1.000 deve estar equipado com Thunderbolt 3 e todos seus concorrentes possuem a porta. A ventoinha de resfriamento não funciona com muita frequência, mas a Dell não conseguiu se livrar do ruído da bobina. O teclado é bom; o touchpad, no entanto, não é impressionante; especialmente em comparação com os concorrentes da HP e Lenovo, o touchpad que a Dell escolheu não é ótimo. Ao contrário da Lenovo e da HP, a Dell escolheu manter a tela de 12,5 polegadas. Isso pode ser uma vantagem ou uma desvantagem: você tem menos superfície de trabalho, mas também menos peso. Uma desvantagem típica das telas de 12,5 polegadas é a falta de cobertura de espaço de cores. Além disso, a tela exibe um forte "bleeding" da iluminação de fundo. Pelo menos, é suficientemente brilhante para usar em exteriores.
A Dell criou um bom conversível: sua longa duração da bateria é particularmente cativante. Mas não é fácil manter-se neste mercado altamente competitivo, e a Dell cometeu alguns erros.
O Latitude 5289 definitivamente não é um conversível ruim. Se você está procurando por um portátil conversível com a maior duração de bateria possível, este pode até ser uma escolha recomendável. No entanto, as alternativas - ThinkPad Yoga 370 e EliteBook x360 - igualmente possuem seus pontos fortes. O modelo de nível de entrada do Latitude custa menos, mas você também recebe uma configuração pior, com apenas 4 GB de memória de trabalho soldada. No geral, o Latitude tem dificuldade em se afirmar contra seus concorrentes. Poderia vencê-los com uma melhor tela de 13,3 polegadas e um touchpad melhorado. Em vez disso, ele permanece em terceiro lugar, apesar da ótimo duração da bateria, especialmente porque os modelos da Lenovo e da HP também oferecem boas durações de bateria.
