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
26 ms ... rise ↗ and fall ↘ combined	↗ 15 ms rise
26 ms ... rise ↗ and fall ↘ combined	↘ 11 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 (20.9 ms).
↔ Response Time 50% Grey to 80% Grey
41 ms ... rise ↗ and fall ↘ combined	↗ 22 ms rise
41 ms ... rise ↗ and fall ↘ combined	↘ 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. » 61 % 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 not detected

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.

O HP ProBook 455 G7 é um acessível portátil de escritório com bom desempenho graças à nova AMD Ryzen 7 4700U. O dispositivo pode ser comprado por pouco menos de 1.000 Euros (~US$ 1.128), pelos quais os compradores recebem não apenas o SoC veloz, mas também 16 GB de RAM e um SSD de 512 GB. As propriedades da tela mate são convincentes e não há PWM. Dito isto, o nível máximo de brilho poderia ser maior. Quando se trata da seleção de portas, o ProBook mal difere do seu antecessor. Graças ao suporte Wi-Fi 6, os usuários agora se beneficiam de transferências de dados sem fio mais rápidas. O número de portas USB é alto e provavelmente suficiente para a rotina diária de um usuário médio. Embora muitos usuários esperem por um, ainda não existe uma porta Thunderbolt 3 no ProBook 455 G7 e, em qualquer caso, a interface deve se tornar um recurso padrão.

Por outro lado, o sensor de digitais e a câmera infravermelha são ótimos extras que tornam o dispositivo uma oferta mais interessante. Ambos funcionam perfeitamente e simplificam os fluxos de trabalho diários. Graças à AMD Ryzen 7 4700U, o desempenho percorreu um longo caminho em comparação com a geração anterior. Mesmo a CPU quad-core Hyper-Threading da Intel não pode competir com este novo SoC.

A HP continua a tomar boas decisões com sua abordagem do ProBook 455 G7. No entanto, gostaríamos de ver uma bateria um pouco maior e uma porta Thunderbolt 3.

Seu sólido desempenho e preço competitivo fazem o HP ProBook 455 G7 valer a pena considerar. No entanto, a HP pode se esforçar para manter a vantagem quando os concorrentes começarem a enviar seus modelos baseados em AMD.

Além disso, ficamos satisfeitos com a duração da bateria, embora 7 horas em nosso teste de Wi-Fi signifiquem que ele não passará um dia de trabalho completo. Dito isto, os concorrentes também não se saem muito melhor nessa categoria. Os dispositivos de entrada são confiáveis e agradáveis de usar, e a unidade base é robusta, sem falhas em termos de qualidade de construção.

The HP ProBook 455 G7 is an affordable office laptop with good performance thanks to the new AMD Ryzen 7 4700U. The device can be purchased for just under 1,000 Euros (~$1,128), for which buyers receive not only the fast SoC but also 16 GB of RAM and a 512-GB SSD. The properties of the matte display are convincing and there is no PWM. That being said, the maximum brightness level could be higher. When it comes to the port selection, the ProBook barely differs from its predecessor. Thanks to Wi-Fi 6 support, users now benefit from faster wireless data transfers. The number of USB ports is high and more than likely sufficient for an average user's daily routine. Even though many users have been hoping for one, there is still no Thunderbolt 3 port on the ProBook 455 G7, and in any case the interface should eventually become a standard feature.

By contrast, the fingerprint sensor and IR camera are nice extras that make the device a more interesting offer. Both work flawlessly and simplify day-to-day workflows. Thanks to the AMD Ryzen 7 4700U, the performance has come a long way compared to the previous generation. Even Intel's Hyper-Threading quad-core CPU cannot compete with this new SoC.

HP continues to make good decisions with its approach to the ProBook 455 G7. However, we would have liked to see a slightly larger battery and a Thunderbolt 3 port.

Its solid performance and competitive price make the HP ProBook 455 G7 worth considering. However, HP may struggle to keep the upper hand once competitors begin to ship their AMD-based models.

Furthermore, we were pleased with the battery life, although 7 hours in our Wi-Fi test means that it will not make it through a full workday. That being said, competitors do not fare much better in this category, either. The input devices are reliable and pleasant to use, and the base unit is robust with no flaws in terms of the build quality.
