Display Response Times

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
31.6 ms ... rise ↗ and fall ↘ combined↗ 18.4 ms rise
↘ 13.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 79 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (26.6 ms).
       Response Time 50% Grey to 80% Grey
46 ms ... rise ↗ and fall ↘ combined↗ 20.8 ms rise
↘ 25.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 70 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.5 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8586 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Lenovo Yoga 920-13IKB
In review: Lenovo Yoga 920-13IKB

Den nya och omdesignade Yoga 920 är den bästa Yoga-modellen i 900-serien och långt från en enkel hårdvaru-uppgradering. Prestandan har definitivt gått upp med en nya fyrakärnig CPU och en blixtsnabb NVMe SSD, men Lenovo har också förbättrat andra områden: den nya omvandlingsbara modellen har nu 2st Thunderbolt 3-portar, en förbättrad placering av webkameran, ett ändrat tangentbord, den stödjer en aktiv stylus för första gången och håller längre på en laddning. Lenovo tog uppenbarligen till sig återkoppling från kunder, vilket är uppfriskande att se.

Aluminium-chassit är vackert och dessutom hyfsat robust och klockrems-gångjärnens design är iögonfallande. Skärmen kunde dock ha varit lite ljusstarkare och kontrast-ration och gråskale-exaktheten kunde också varit bättre. Sen är det frågan om storleken: Yoga är fortfarande en av dom större omvandlingsbara modellerna där ute, vilket gör att den inte är lätt att hålla i surfplatte-läge. En del användare kan dock uppskatta den extra skärmytan. Avsaknaden av en "Lift'n Lock"-funktion likt på Thinkpad lämnar också Yogas knappar blottade, så man behöver vara försiktig för att undvika skada. Strypningen under tung belastning inskränker den höga prestanda-potentialen hos dom extra CPU-kärnorna något, men helhetsprestandan har fortfarande gått upp, så vi skulle inte klassa det som en stor nackdel. Ytterligare ett plus, det irriterande visslande ljudet vi stötte på i vår recension av föregångaren Yoga 910 är definitivt inte längre ett problem.

Yoga 920 är en väldigt väldesignad och attraktiv 2-i-1. Användare som överväger omvandlingsbara modeller på 13.3 tum som HP Spectre x360 eller Dell XPS 13 borde definitivt också ta en titt på den aningen större Yoga.
