Display Response Times
ℹ
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 | ||
|---|---|---|
| 30 ms ... rise ↗ and fall ↘ combined | ↗ 17 ms rise |  |
| ↘ 13 ms fall | ||
| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 78 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 40 ms ... rise ↗ and fall ↘ combined | ↗ 22 ms rise |  |
| ↘ 18 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. » 58 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
ℹ
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 detected | 192 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 192 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 192 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. | |||

Contra
- A CPU fica atrás de suas capacidades
- A RAM de um só canal limita o desempenho gráfico
- A tela escurece consideravelmente durante a operação com bateria
Veredicto - Dispositivo de trabalho equilibrado
A HP oferece um portátil sólido com o ProBook 445 G7, que não apenas oferece bom desempenho no escritório, mas também fornece reservas de desempenho para tarefas um pouco mais exigentes. Embora todo o potencial de desempenho do AMD Ryzen 5 4500U não é aproveitado, o desempenho ainda é muito bom e o consumo de energia também é mantido dentro de limites. Por sua vez, isso afeta positivamente a duração da bateria, o que permite que os usuários trabalhem por longos períodos longe da tomada, principalmente por causa do bom teclado.
O HP ProBook 445 G7 oferece um bom compromisso entre desempenho e consumo de energia, mas reduz muito o brilho da tela no modo bateria.
O HP ProBook 445 G7 apresenta um problema completamente diferente sem uma fonte de alimentação conectada. O brilho aceitável da tela cai para um valor de 163 cd/m² no modo bateria, o que significa que o brilho em exteriores não é mais forte o suficiente para competir com a luz ambiente, mesmo na sombra. Aqui, os usuários precisam acessar as configurações da Radeon por conta própria e desativar a opção Vari-Bright. Como basicamente todos os outros recursos falam positivamente pelo ProBook 445 G7, esse é um problema desnecessário.
