Test: Lenovo Yoga C940-14IIL - Lyxig omvandlingsbar med Ice Lake som är en stark konkurrent till Dell XPS 13 (Sammanfattning)

Benjamin Herzig, 👁 Andreas Osthoff (översatt av Daniel Eriksson), 10/18/2019

Ice Lake Yoga. Lenovo vill ta sin lyxiga omvandlingsbara Yoga till nästa nivå med hjälp av de senaste Ice Lake-processorerna från Intel. Det är inte mycket Lenovo har ändrat jämfört med den föregående modellen och man har istället valt att jobba på en del svaga punkter. I vår recension visar det sig att den strategin betalar sig väl!

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
30 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 13.6 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. » 73 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.8 ms).
       Response Time 50% Grey to 80% Grey
49.6 ms ... rise ↗ and fall ↘ combined↗ 23.6 ms rise
↘ 26 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. » 83 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.4 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: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9364 (minimum: 43 - maximum: 142900) Hz was measured.

Läs den fullständiga versionen av den här recensionen på engelska här.

Lenovo fortsätter sin lyxiga Yoga-serie med Yoga C940-14IIL och har för första gången utrustat den med de senaste Ice Lake-processorerna. Det här är en väl utförd evolutionär uppdatering.

Det är ingen tvekan om att nya Intel Core i7-1065G7 är hjärtat i denna Yoga-platta. I fråga om CPU- och i synnerhet GPU-prestanda innebär den nya plattformen en stor förbättring, vilket gör Yoga C940 lämplig för lättare gaming. Detta har gått att uppnå utan att värmeutvecklingen eller ljudnivån ökat – faktum är att båda istället har minskat. Batteritiden är fortfarande bra. Jämfört med Yoga C930 har den en ny och mer ljusstark FHD-skärm, vilket definitivt är en välkommen förbättring. Utöver det har Lenovos dator kvar många goda egenskaper från sin föregångare, såsom den lyxiga metallkonstruktionen, den inbyggda stylusen och det starka fyrdubbla högtalarsystemet.

Den har knappt några svaga punkter alls. En av få är definitivt bristen på portar samt en mindre mängd spoltjut. Det är dessutom onödigt svårt att öppna Yoga C940 (eftersom skruvarna är gömda under gummifötter). Det hade också varit trevligt om Lenovo erbjöd ett matt skärmalternativ och om LCD-panelen kunde nå upp till den utlovade ljusstyrkan på 400 cd/m².

Lenovo gör i det här fallet inte några avgörande fel  – vilket är anledningen till att Lenovo Yoga C940-14IIL troligen kommer hamna på många önskelistor den här julen.

Vi tycker inte att de svaga punkterna är avgörande utan kan istället helhjärtat rekommendera Lenovo Yoga C940-14IIL. Det är en lyxig laptop som erbjuder hög kvalitet och stor flexibilitet, vilket målgrupper som studenter kommer uppskatta. Dell XPS 13 7390 2-in-1 har fått en stark konkurrent.
