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 | ||
|---|---|---|
| 34.4 ms ... rise ↗ and fall ↘ combined | ↗ 16.4 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 0.1 (minimum) to 240 (maximum) ms. » 91 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms). | ||

| 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. » 95 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Fomos entusiasmados com a profundidade e qualidade das cores assim que vimos pela primeira vez a cor do fundo padrão da área de trabalho. Essa impressão foi agravada assistindo alguns vídeos curtos. Finalmente, há um ThinkPad com uma tela excelente que também não decepciona em outras áreas. A tela WQHD HDR do X1 Carbon também supera o já bom painel 4K encontrado no workstation móvel ThinkPad P71. O acabamento brilhante é uma desvantagem para a tela WQHD HDR, especialmente se você planeja usar o dispositivo quando viaja. Felizmente, a Lenovo ainda oferece o painel WQHD mate do modelo do ano passado.
No entanto, estamos confusos com as mudanças nos limites de temperatura. Enquanto ao remover os limites de temperatura da CPU do modelo do ano passado beneficia o desempenho e o sistema permanece estável, as temperaturas da superfície atingem mais de 50 °C sob carga. Talvez, então, a Lenovo melhor não deveria remover completamente esses limites de temperatura. Vamos monitorar isso de perto com testes adicionais, já que não podemos concluir definitivamente depois de um pouco mais de meio dia de testes.
Estamos curiosos para ver como o novo X1 Carbon se compara com o X280 e T480s revisados que também estão atualmente em teste. Também esperamos suas perguntas e sugestões.
