Tela ruim. O portátil empresarial da HP de 14 polegadas também recebe a atualização Kaby Lake. No entanto, como com o irmão maior de 15 polegadas não estamos convencidos pela tela.

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
24.4 ms ... rise ↗ and fall ↘ combined↗ 7.2 ms rise
↘ 17.2 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 51 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.6 ms).
       Response Time 50% Grey to 80% Grey
43.2 ms ... rise ↗ and fall ↘ combined↗ 21.2 ms rise
↘ 22 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 68 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.9 ms).

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 18071 (minimum: 5 - maximum: 3846000) Hz was measured.

In review: HP ProBook 440 G4. Test model courtesy of HP Germany.

O HP ProBook 440 G4 é muito similar a seus irmãos, o que inclui os aspectos positivos e negativos. É um aparelho empresarial de nível de entrada, portanto, você terá que viver com alguns compromissos. Isto inclui alguns recursos faltantes como o leitor de SmartCard ou a porta docking. O ProBook também fica atrás de produtos mais caros como os próprios EliteBooks da HP em termos de qualidade da carcaça e variedade de portas.

No entanto, o maior problema do ProBook 440 G4 é a tela. O nosso modelo de teste já está equipado com a "melhor" tela que você pode receber por este sistema, mas ainda estamos decepcionados. Nós não entendemos por que a HP nem sequer oferece um painel IPS como uma opção, e também analisamos melhores painéis TN no passado. 

O HP ProBook 440 G4 é veloz, oferece um bom chassi e um teclado confortável, mas a tela é difícil de justificar por um preço de mais de 1000 Euros (~$1074).

O desempenho do ProBook 440 G4 não decepciona, porque o sistema pode lidar com muitos aplicativos graças ao veloz processador e ao SSD. Se você pode se beneficiar da GPU dedicada GPU é outra questão. Obviamente é mais poderoso que o adaptador integrado, mas isto é notório principalmente durante os jogos. Você definitivamente pode selecionar um SKU com um Core i5 e gráficos integrados se deseja economizar um pouco de dinheiro. Ainda não é fácil recomendar a versão de 14 polegadas do ProBook para todos os usuários devido à decepcionante tela.
