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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured.

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
26 ms ... rise ↗ and fall ↘ combined↗ 7 ms rise
↘ 19 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 59 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
35 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 44 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (32.9 ms).

In review: HP EliteBook 820 G4 Z2V72ET. Test model provided by Notebooksbilliger.de

Inclusive se o HP EliteBook 820 G4 é, mais que nada, uma atualização Kaby Lake, poderia ser interessante para os proprietários do predecessor. No entanto, isto não se deve ao baixo ganho de desempenho do Kaby Lake em comparação com Skylake.

Durações de bateria bastante mais longas, tornam o computador (mais) atraente.

Sem importar a carga, o computador permanece frio e funciona de forma silenciosa a maior parte do tempo. Este último se aplica desde que a ventoinha pare ou funciona a uma velocidade muito baixa. De outra forma, você pode ouvir um baixo ruído de assobio. Isto não deveria acontecer em computadores desta faixa de preços; ainda mais, porque já criticamos isso no antecessor.

O muito veloz NVMe-SSD garante u sistema responsivo. É possível substituir o SSD. Isto requer remover o lado inferior do portátil - que não precisa de muito esforço. A carcaça e o teclado permaneceram iguais: A HP fornece a qualidade com a que já estamos acostumados.

Não é muito frequentemente que podemos dizer algo bom das telas dos portáteis empresariais da HP. No entanto, as coisas mudaram desta vez: A HP incorporou um painel IPS brilhante, rico em contraste e com ângulos de visão estáveis. Inclusive as cores são bastante boas de fábrica.
