Kort testrapport Lenovo IdeaPad Miix 720 (7500U, QHD) Convertible Laptop

3:2 Surface. Met zijn QHD beeldscherm en Kaby Lake 15-watt SoC, vertegenwoordigd de Lenovo IdeaPad Miix 720 een formidabele uitdager voor de Microsoft Surface. Maar de ongebalanceerde ventilatoren en lage kwaliteit microfoon verpesten het 12-inch model voor ons.

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
24 ms ... stijging ↗ en daling ↘ gecombineerd↗ 14 ms stijging
↘ 10 ms daling
Het scherm vertoonde prima responstijden in onze tests maar is misschien wat te traag voor competitieve games.
Ter vergelijking: alle testtoestellen variëren van 0.8 (minimum) tot 240 (maximum) ms. » 37 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (24.1 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
45 ms ... stijging ↗ en daling ↘ gecombineerd↗ 22 ms stijging
↘ 23 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.8 (minimum) tot 636 (maximum) ms. » 69 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (38.2 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: 52 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 9706 (minimum: 5 - maximum: 151500) Hz waargenomen.

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

Lenovo heeft met de IdeaPad Miix 720 zijn antwoord op de Surface Pro 4 gelanceerd, met name de 3:2 beeldverhouding en de hoge resolutie (2736 x 1824 voor de Surface, 2880 x 1920 voor de Miix 720) maken de beide apparaten onderling uitwisselbaar. Qua beeldscherm is er geen kritiek, op misschien het kleurbereik na, maar dat zou niet recht doen aan het beeldscherm.

Het voordeel van de Miix is dat deze uitgerust is met vele aansluitingen: 2x normale USB 3.0 Type-A, USB Type-C gen.2 met Thunderbolt 3 en dan ook nog een IR camera voor Windows Hello. Intern bevind zich een Kaby Lake processor en een enorme RAID-SSD opstelling, die erg snel is.

Helaas kan de Miix 720 niet de volle prestaties van de SoC benutten, bij constante belasting door alledaagse applicaties zorgt throttling voor 10% minder prestaties. Hiermee bevinden de prestaties zich op hetzelfde niveau als de Surface Pro 4 i7. Zelf aanzienlijk goedkopere modellen zoals de Aspire Switch Alpha 12 (i5) zijn naar verwachting sneller of in elk geval net zo snel.

De Switch Alpha 12 met i5 is al te koop vanaf € 750, de Microsoft Surface Pro 4 + Type Cover (i5-6300U) vanaf € 1200. Dat brengt de volgende vraag: waarom de Miix 720 kopen wanneer de processor prestaties beneden verwachting zijn?

De Miix 720 is zeker niet goedkoop: de 7500U, 16 GB en 1 TB SSD versie kost € 1700. Voor de meeste gebruikers met mobiele voorkeur zal een lichtere versie met 256 GB of 128 GB en Core i3 of i5 7200U waarschijnlijk ook al voldoende zijn. Deze zijn beschikbaar vanaf € 1070.

De lichtere variant laat je ook genieten van de voordelen van Thunderbolt 3, batterijlevensduur, fantastisch beeldscherm, IR camera met Windows Hello en veelzijdig toetsenbord (verlicht). Op korte termijn zullen de prijzen dalen, en zal naar verwachting € 900 voor de lichte i3 versie een heel concurrerende aanbieding zijn.
