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 | ||
|---|---|---|
| 36.4 ms ... rise ↗ and fall ↘ combined | ↗ 21.2 ms rise |  |
| ↘ 15.2 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. » 94 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms). | ||
| ↔ Response Time 50% Grey to 80% Grey | ||
| 48.4 ms ... rise ↗ and fall ↘ combined | ↗ 24.4 ms rise |  |
| ↘ 24 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. » 82 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

När Dell utannonserade XPS 15 2-in-1 förväntade vi oss en vanlig ihopvikbar XPS 15 men med 360-gradersgångjärn. Istället fick vi ett helt annat chassi med en oprövad CPU/GPU-serie som kan ha gjort fans av XPS 15 tveksamma. Lenovo Yoga C940-15 är faktiskt närmare det som de flesta användare nog väntat sig att XPS 15 2-in-1 skulle varit: en omvandlingsbar med tryckkänslig skärm, ett traditionellt chiclet-tangentbord, en vanlig Intel Core H CPU, en GeForce GTX GPU, lagring som är lätt att byta och ett säkrare garage för pennan istället för en kinkig magnetisk lösning.
Att ha en spelkapabel GTX GPU i en 15.6-tums omvandlingsbar har sina nackdelar. I synnerhet då surfplatteläget passar bäst för att användas då och då eller i korta stunder med tanke på enhetens storlek och vikt. Men Yoga C940 är ändå lättare, mindre, mer ljusstark och mer kraftfull än konkurrenten HP Spectre x360 15 2019, vilket gör den till ett bättre alternativ i den här specifika kategorin. XPS 15 9575 2-in-1 är en liten bit mindre, men den är sämre på de flesta andra områden inklusive prestanda, batteritid, ljusstyrka och ljud. Vi hoppas att framtida versioner kommer förbättra den höga vikten och de mjuka tangentbordsknapparna samt den mjuka klickplattan.
Lenovo Yoga C940-15 har riktigt hög prestanda i förhållande till sin volym för en omvandlingsbar på 15.6 tum. Även om den varken är särskilt lätt eller billig till ett pris av 15.000 kronor är den ett bättre alternativ jämfört med XPS 15 2-in-1 eller senaste HP Spectre x360 15.
