Kort testrapport Lenovo Yoga 720 12 (i5-7200U, 128 GB) Convertible

Veelzijdig met beperkt uithoudingsvermogen. Lenovo's nieuwste compacte notebook heeft een fraaie aluminium behuizing en veelzijdige 360-graden scharnieren, maar werkt ook goed als zakelijke subnotebook. Belangrijke voordelen zoals het beeldscherm en de invoerapparaten worden tegengewerkt door een aantal minpunten, waarvan met name één voor problemen kan gaan zorgen.

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↗ 16 ms stijging
↘ 10 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. » 45 % 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
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. » 18 % 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 niet waargenomen

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.

Zakelijke gebruikers zullen twee problemen ondervinden met de goed ontworpen Lenovo Yoga 720-12IKB: de relatief langzame WLAN module en – nog belangrijker – de relatief zwakke batterij die het geen volledige werkdag volhoudt. Het geweldige beeldscherm is goed voor ieder gebruik behalve serieuze beeldbewerking en de langzame SSD benchmarkresultaten hebben geen invloed op de algehele systeemprestaties. Een beperkt aanbod van poorten is gebruikelijk voor convertibles, dus zien we gebreken op dit vlak door de vingers.

De stabiliteit van de behuizing is niet perfect, maar het is nog steeds een goed ontworpen, degelijk apparaat. De meegeleverde Active Pen, degelijke invoerapparaten en het koele, stille gebruik zijn verdere voordelen.

De compacte en veelzijdige Lenovo Yoga 720 12 is betaalbaar en voldoet aan vrijwel alle eisen van mobiele zakelijke gebruikers. Het enige grote nadeel is de korte batterijlevensduur.

Alles bij elkaar kunnen we het apparaat een aanbeveling geven.
