Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 210.1 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 210.1 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 210.1 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. 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. | |||

Verdict
O Dell Latitude 12 5285 é um sólido conversível empresarial. O 2-em-1 combinas boa ergonomia, boa velocidade e muita duração em uma pacote compacto e atraente. Sim, parece muito com o Microsoft Surface Pro 4, mas nós honestamente não esperamos que a Dell aliene o que foi um conceito bem sucedido, apenas para quebrar o molde. O "Travel Keyboard" oferece uma resposta sólida e oferece uma iluminação de fundo de dois níveis, para começar. A Active Stylus funciona muito bem como um dispositivo de entrada adicional e oferece funcionalidades adicionais como inicializar o Microsoft OneNote ou outros aplicativos. Onde a Dell difere de sua concorrência é em duas áreas chave: primeiramente, embora a resolução da tela seja inferior - o qual não é algo que nós consideramos uma desvantagem significante, dada a orientação empresarial do Latitude - o painel é extremamente brilhante e supera facilmente a concorrência. Além disso, o hardware 2-em-1 é muito fácil de acessar e manter, o qual sempre foi um calcanhar de Aquiles para os conversíveis.
O recurso destacado do Latitude é, sem dúvida, a sua tela, que é incrivelmente brilhante com uma luminância média de mais de520 nits.
Do que menos gostamos: o 5285 esquenta bastante sob uso intenso e também é um pouco mais pesado que a concorrência. Também seria boa uma porta Thunderbolt 3. O Latitude também é bastante caro, o que para muito usuários poderia tornar outros conversíveis, como o Asus Transformer 3 Pro ou o Acer Aspire Switch Alpha 12, resfriado com líquido, mais atraentes, apesar de sua duração de bateria muito mais breve. O Microsoft Surface Pro 4 ainda é uma boa opção - particularmente a versão com Core i5 e SSD de 256 GB, que é vendida por pouco mais de $1300.
