Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 199.2 Hz | ≤ 50 % brightness setting |  |
The display backlight flickers at 199.2 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 199.2 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Resumir o EliteBook 850 G4 é bastante frustrante. Embora a HP marque todas as caixas de verificação corretas com este aparelho, ainda consegue nos decepcionar no final. A carcaça é sólida e muito bem construída, os dispositivos de entrada são bons (embora não perfeitos), o resfriamento funciona brilhantemente, e a duração da bateria é muito boa, considerando a capacidade da bateria. Em resumo, não há muito o que criticar mais que a ausência do Thunderbolt 3, a manutenção complicada, ou seu alto preço.
Infelizmente, tudo isto é manchado pela tradição da HP de equipar seus portáteis premium com telas TN de má qualidade. Depois de tudo, o modelo que testamos custa mais de 1.400 Euros (~$1491), e inclusive o modelo top que deixará um buraco de 1.700-Euros (~$1811) em seu bolso vem com exatamente a mesma tela. Sim, ela é brilhante, mas fora isso, mostra todas as "qualidades" que você esperaria de um painel TN. A opção UHD IPS listada na folha de especificações, ainda não está disponível na Alemanha.
A HP marca todas as caixas de verificação corretas... exceto uma: o painel TN do EliteBook 850 G4 estraga a muito boa impressão que ele deixou.
É por isso, apesar de todas suas capacidades e qualidades que não podemos recomendar o EliteBook 850 G4. Cinco anos atrás teria sido uma história completamente diferente: antes, quase todos os portáteis empresariais vinham equipados com telas similarmente ruins. No entanto, a HP aprece ser a única que não recebeu o memorando, e os paineis TN estão extintos em portáteis da mesma faixa de preços. Seu principal concorrente oferece paineis IPS Full HD exclusivamente em seus aparelhos empresariais premium, hoje em dia. Inclusive o painel IPS desagradável do ThinkPad T570 derrota facilmente o painel TN do EliteBook, sem mencionar os paineis IPS de alta qualidade, como o do Fujitsu Lifebook U757.
Pro
Contra
Summing up the EliteBook 850 G4 is rather frustrating. While HP does tick all the right boxes with this device, it still manages to disappoint in the end. The case is very well built and sturdy, the input devices are decent (although not perfect), cooling works brilliantly, and battery life is very good considering the battery capacity. All-in-all, there's not much to criticize other than maybe the lack of Thunderbolt 3, the rather intricate maintenance, or its high price.
Unfortunately, all this is overshadowed by HP's tradition of equipping its premium and upscale business laptops with shoddy TN displays. After all, the model we've tested clocks in at slightly over 1,400 Euros (~$1491), and even the top model that will leave a 1,700-Euro (~$1811) dent in your pocket comes with the exact same display. Yes, it's bright, but other than that it shows all the "qualities" you come to expect from a TN panel. The UHD IPS option listed in the laptop's spec sheet is not yet available in Germany.
HP ticks all the right boxes...except for one: the EliteBook 850 G4's TN panel ruins the otherwise very good impression it makes.
This is why, despite all of its capabilities and qualities, we cannot recommend the EliteBook 850 G4. Five years ago it would've been a completely different story: back then almost all business laptops came equipped with similarly poor displays. However, HP seems to be the only one that hasn't gotten the memo, and TN panels are all but extinct in similarly priced laptops. Its main competitors offer Full HD IPS panels exclusively in their premium business devices these days. Even the ThinkPad T570's rather dodgy IPS panel beats the EliteBook's shoddy TN panel hands down, not to mention high-quality IPS panels such as the one in Fujitsu's Lifebook U757.
