Responstijd Scherm

De responstijden van het scherm tonen hoe snel het scherm in staat is om van één kleur naar de andere te veranderen. Trage responstijden kunnen aanleiding geven tot 'nabeelden' rond bewegende objecten of het scherm wazig maken (blur). Vooral spelers van snelle 3D-games hebben baat bij een scherm met snelle responstijden.
       Responstijd Zwart naar Wit
26 ms ... stijging ↗ en daling ↘ gecombineerd↗ 15 ms stijging
↘ 11 ms daling
Het scherm vertoonde relatief trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.8 (minimum) tot 240 (maximum) ms. » 42 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (26.7 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
32 ms ... stijging ↗ en daling ↘ gecombineerd↗ 15 ms stijging
↘ 17 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.9 (minimum) tot 636 (maximum) ms. » 17 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd beter is dan het gemiddelde (42.8 ms) van alle geteste toestellen.

Screen Flickering / PWM (Pulse-Width Modulation)

Om de schermhelderheid te verlagen schakelen sommige laptops het backlight erg snel aan en uit. Dit gebeurt aan een dergelijk hoge frequentie dat het niet zichtbaar is voor het menselijk oog. Als de frequentie te laag is kunnen personen met gevoelige ogen geïrriteerd geraken, hoofdpijn krijgen en zelfs flickering waarnemen.
Screen flickering / PWM niet waargenomen

Ter vergelijking: 57 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 6577 (minimum: 43 - maximum: 142900) Hz waargenomen.

Dit is de verkorte versie van het originele artikel. Het volledige, Engelse testrapport vind je hier.

Lenovo's Yoga 720-13IKB is een solide, veelzijdige 13-inch convertible met een goed uithoudingsvermogen, laag gewicht, klein formaat en 360-graden scharnier. Het is gebaseerd op Intel's Kaby Lake huidige generatie Core i5-7200U, 8 GB RAM en is voldoende snel dankzij de hoog-presterende 256 GB SSD. Gecombineerd met een FHD beeldscherm kan de hele configuratie aangeschaft worden vanaf $ 850.

We zijn overtuigd door het tijdloze minimalistische "niet-meer-dan-noodzakelijk"-design en de materiaalkeuze. De Yoga 720-13IKB voldoet aan bijna alle punten en steunt overduidelijk op de ruime ervaring en tests van Lenovo. Helaas betekent dit ook dat er slechts drie poorten zijn.

Al met al maakt de Lenovo Yoga 720-13IKB een positieve indruk, hoewel we niet volledig begrijpen waarom er geen SD-kaartlezer is. Het lijkt bijna alsof Lenovo het minimalistische "minder is meer" adagio van Apple probeert te imiteren. Uiteindelijk zal de consument moeten beslissen of deze compromissen de aanschaf waard zijn. Ons testmodel biedt solide en stabiele prestaties en we kwamen geen serieuze problemen tegen tijdens het testen van deze laptop. De invoerapparaten zijn prettig in gebruik en gezien dit alles is de prijs van $ 850 voor een moderne laptop meer dan gerechtvaardigd.
