Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 926 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 926 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 926 Hz is quite high, so most users sensitive to PWM should not notice any flickering. 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. | |||

O T570 mais caro, consegue nos convencer, assim como o modelo mais acessível. Ele possui características muito boas que a nossa unidade de teste inicial também teve: a carcaça robusta e relativamente compacta, os confortáveis dispositivos de entrada, bem como as muitas opções de conexão. Recursos práticos como PowerBridge ou a câmera com infravermelhos, tornam o T570 em um portátil muito flexível. Além das vantagens do acessível T570, agora também vem a tela 4K de uma qualidade convincente e a GPU NVIDIA, que, apesar de ser um modelo mais antigo, é consideravelmente mais poderosa que a GPU da Intel integrada na CPU.
No entanto, este modelo também não é impecável. Nosso maior reclamo e a redução forçado do desempenho da CPU durante a operação com bateria. Durante a operação na tomada, conseguimos evitar as flutuações do desempenho neste modelo com uma modificação nas configurações, mas o desempenho durante a operação com bateria não pode ser incrementado desta forma. Um novo problema adicional é o aquecimento no lado inferior durante o uso intenso, que provavelmente possa ser atribuído à GPU da Nvidia. Em termos deste problema, o T560 se saiu um pouco melhor, talvez por causa de sua carcaça mais grossa e maior. Elém disso, o preço para a versão não-estudante do T570, com tela 4K e GPU Nvidia não é muito acessível, e a fonte de energia fornecida não é suficiente durante o uso intenso.
Com a tela 4K, o T570 apresenta um bom pacote geral e é um candidato promissor no segmento de 15,6 polegadas, dado que oferece uma combinação interessante de recursos empresariais e características multimídia.
Em resumo, o T570 com uma tela 4K, pode ser claramente recomendado. Com esta tela, ele melhorou muito em uma área crucial, onde a unidade de teste inicial tinha decepcionado. Se não fosse pela redução do desempenho durante a operação com bateria, teria atingido uma recomendação "muito boa". Aqui reduzimos a avaliação final em dois pontos percentuais. Com isto, a redução é um pouco menor que para a primeira unidade de teste, dado que desta vez, a GPU não é afetada pela redução do desempenho e a operação na tomada é estável.
Existe infinidade de alternativas com uma tela de 15,6 polegadas, enquanto o setor empresarial, em particular, está mais concentrado no formato de 14 polegadas. O MacBook Pro 15 e o Dell XPS 15 são fortes concorrentes, que não oferecem os recursos empresariais e o excelente teclado do T570, mas opções de GPU e CPU bastantes mais poderosas.
Pro
Contra
The more expensive T570 can convince us just as much as the more affordable model. It has many good characteristics that our initial test unit also had: the robust, relatively compact case, the comfortable input devices, as well as the many connection options. Practical features such as PowerBridge or the infrared camera turn the T570 into a very flexible laptop. In addition to the advantages from the affordable T570, now also come the 4K display of a convincing quality and the NVIDIA GPU, which, despite being an older model, is considerably more powerful than the Intel GPU integrated into the CPU.
However, this model is also not without problems. Our biggest complaint is the enforced CPU performance reduction during battery operation. During mains operation, we could avoid the performance fluctuations in this model with a settings change, but the performance during battery operation cannot be raised in this way. An added, new problem is the heat development on the bottom during load, which can probably be attributed to the Nvidia GPU. In terms of this problem, the T560 did a little better, perhaps due to its thicker and larger case. In addition, the price for the non-student version of the T570 with 4K display and Nvidia GPU is not really very affordable, and the supplied power supply is not sufficiently sized for operation during load.
With the 4K display, the T570 presents a good overall package and is a promising candidate in the 15.6-inch segment, since it offers an interesting combination of business features and multimedia characteristics.
In summary, the T570 with a 4K display can be clearly recommended. With this display, it was markedly improved in a crucial area where the initial test unit had disappointed. If it were not for the performance reduction during battery operation, it would have achieved a "very good" recommendation. Here we reduce the end note by two percentage points. With this, the reduction is slightly less than for the first test unit, since at this time, the GPU is not affected by the performance reduction and the performance in mains operation is stable.
There are countless alternatives with a 15.6-inch display, whereas the business sector in particular is more concentrated on the 14-inch format. The MacBook Pro 15 and the Dell XPS 15 are strong competitors, which do not offer the business features and the excellent keyboard of the T570, but considerably stronger GPU and CPU options, instead.
