Kort testrapport Lenovo Ideapad 720S-13IKB (i5-8250U, UHD 620) Laptop

Mike Wobker (vertaald door Siemon Boes), 10-02-2018

Ultramobiele kantoorprestaties. Lenovo noemt de nieuwe Ideapad 720s een "extreem performant en stijlvol toestel". We zouden dit niet zo verwoorden, maar de prestaties zijn niettemin indrukwekkend voor een notebook die slechts 13 mm dik is. We achterhalen wat je precies kan verwachten van de 720s in zijn verschillende configuraties.

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
25 ms ... stijging ↗ en daling ↘ gecombineerd↗ 14 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. » 38 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (26 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
35 ms ... stijging ↗ en daling ↘ gecombineerd↗ 17 ms stijging
↘ 18 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. » 25 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd beter is dan het gemiddelde (41.6 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 waargenomen 131000 Hz ≤ 90 % helderheid instelling

Het backlight van het scherm flikkert aan 131000 Hz (hoogstwaarschijnlijk met PWM - Pulse-Width Modulation) aan een helderheid van 90 % en lager. Boven deze helderheid zou er geen flickering / PWM mogen optreden.

De frequentie van 131000 Hz is redelijk hoog en de meeste mensen die gevoelig zijn aan flickering zouden dit dus niet mogen waarnemen of geïrriteerde ogen krijgen.

Ter vergelijking: 54 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 10727 (minimum: 43 - maximum: 588200) Hz waargenomen.

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

De Ideapad 720s van Lenovo is een erg lichte en ultradunne notebook geschikt voor alledaagse kantoortaken. De Ideapad 720s was een van de enige toestellen in onze test die in staat was om consistente prestaties aan te houden onder belasting. Zelfs bij extreme omstandigheden kon de koeling verzekeren dat het systeem bruikbaar bleef. De onderhoudsopties zijn echter beperkt en Lenovo concentreerde zich alleen op de meest essentiële connecties. Dankzij de Thunderbolt-connecties kunnen alle nodige poorten met de juiste adapters voorzien worden.

Met de Lonovo Ideapad 720s krijgt de koper een erg dunne en lichte notebook die dienst kan doen als betrouwbaar werkpaard.

In het huidige aanbod kan de Ideapad 720s uitgerust worden met een Kaby Lake-CPU van de 8ste generatie. De koper zal echter zijn eigen voorkeur moeten volgen om te beslissen of de modellen met AMD's Ryzen 5 2500U of de Kaby Lake-processors van de 7de generatie hun prijs waard zijn.
