Notebookcheck

Test: Lenovo Yoga 720 12 (i5-7200U, 128 GB) Omvandlingsbar (Sammanfattning)

Mångsidig med begränsad uthållighet. Lenovos nya kompakta enhet får ett tjusigt aluminiumhölje och mångsidiga 360-gradersgångjärn, men fungerar också bra som en traditionell kontors-subnotebook. Viktiga fördelar såsom skärm och inmatningsenheter bemöts av ett mindre antal nackdelar, men dom flesta intresserade köpare borde tycka dessa är okej – bortsett från en.

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
26 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 10 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 0.8 (minimum) to 240 (maximum) ms. » 45 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.9 ms).
       Response Time 50% Grey to 80% Grey
32 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 17 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. » 18 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41.4 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: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8882 (minimum: 43 - maximum: 142900) Hz was measured.

In review: Lenovo Yoga 720 12. Test model courtesy of Campuspoint.

Kontorsanvändare kommer notera två nackdelar hos den annars väldesignade Lenovo Yoga 720-12IKB – den jämförelsevis långsamma WLAN-modulen och, viktigast, batteritiden täcker inte en hel arbetsdag på resande fot. Valet av skärm är väldigt bra bortsett från seriös bildredigering och de långsamma resultaten från SSD-prestandatesten påverkar inte den bra systemprestandan. Begränsat utbud av portar är vanligt bland kompakta omvandlingsbara, så vi kan knappast kritisera Yoga för det.

Höljets stabilitet är inte perfekt, men det är fortfarande ett lyckat chassi med en snygg design och bra konstruktionskvalitet. Active Pen, som ingår, dom hyfsade inmatningsenheterna, inklusive en tryckkänslig skärm, samt den effektiva, svala och väldigt tysta driften är andra fördelar.

Den kompakta och mångsidiga omvandlingsbara Lenovo Yoga 720 12 är billig och svarar upp mot nästan alla krav från mobila företagsanvändare. Den enda egentliga nackdelen är den begränsade uthållighet vid batteridrift.

Allt som allt så kan vi rekommendera denna testmodell.
