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 | ||
|---|---|---|
| 28.8 ms ... rise ↗ and fall ↘ combined | ↗ 17.2 ms rise |  |
| ↘ 11.6 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. » 74 % 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 | ||
| 40.4 ms ... rise ↗ and fall ↘ combined | ↗ 22.4 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 0.165 (minimum) to 636 (maximum) ms. » 60 % 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 8702 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
- Caro
- Cobertura do espaço de cor medíocre
- Pesado para um 2-em-1
- Tela muito escura
- Problemas com o reflexo
- Alto-falantes finos e nada agradáveis
- Um pouco desconfortável de usar no modo tablet devido ao tamanho
- A ausência das teclas de volume dedicadas dificulta o ajuste do volume no modo tablet
Mantivemos a variante HDR Core i7 do 2018 X1 Yoga em uma luz positiva. Elogiamos seu chassi bem construído, bom desempenho e operação silenciosa, mas tivemos alguns problemas com seu alto preço. Por $2400, esse modelo do X1 Yoga pode estar fora da faixa de preços da maioria dos usuários. Por $600 a menos, o modelo Core i5 FHD é melhor para o orçamento, mantendo a maioria das sutilezas do modelo mais caro.
A diferença de desempenho entre o Core i5-8250U e o Core i7-8550U é insignificante na melhor das hipóteses. Como tal, a maioria dos usuários não verá nenhuma mudança perceptível, afogando o desempenho da CPU. Em vez de investir em um processador um pouco mais rápido, os compradores em potencial devem investir esse dinheiro na tela HDR WQHD, que é cerca de $170 a mais. O painel mais caro dobra o brilho e possui um contraste e reprodução de cor quase inigualáveis. A melhor configuração disponível seria um emparelhamento do Core i5-8250U e da tela WQHD HDR.
A variante do Core i5 do X1 Yoga retém as melhores peças de seu irmão mais caro enquanto corta custos. Por $600 a menos, o Yoga Core i5 FHD X1 oferece desempenho similar envolto no mesmo excelente chassi. Se você está à procura de um conversível de classe executiva e pode abrir mão de um aumento de 5% na capacidade de processamento da tela HDR, essa é a máquina que você deve ter.
