Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM waargenomen | 198.4 Hz | ≤ 99 % helderheid instelling | |
Het backlight van het scherm flikkert aan 198.4 Hz (hoogstwaarschijnlijk met PWM - Pulse-Width Modulation) aan een helderheid van 99 % en lager. Boven deze helderheid zou er geen flickering / PWM mogen optreden. De frequentie van 198.4 Hz is redelijk laag en de meeste mensen die gevoelig zijn aan flickering kunnen dit dus waarnemen of geïrriteerde ogen krijgen (gebruikmakend van de vermelde helderheid en lager). 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 9953 (minimum: 43 - maximum: 588200) Hz waargenomen. |

Dit is de verkorte versie van het originele artikel. Het volledige, Engelse testrapport vind je hier.
De beste eigenschappen van de Miix 520 zijn de processor prestaties, SSD prestaties, veelzijdigheid van poorten en de prijs. De prestaties-per-euro zijn een van de beste op de markt op dit moment, doordat de meeste andere Windows tablets nog een processor uit de Core Y-serie of Core i van de 7e generatie gebruiken. Gebruikers die deze extra rekenkracht kunnen gebruiken zullen de Miix 520 dan ook een bijna-Ultrabook niveau reisgezel vinden.
Al het andere aan de Lenovo convertible is niet noodzakelijk slecht of matig, maar er is zeker ruimte voor verbetering in vergelijking met enkele alternatieven. De Surface Pro en Elite x2 hebben een robuuster ontwerp, een helderder en hogere resolutie beeldscherm, nauwkeuriger kleuren en langere batterijlevensduur. Met name het HP tablet, die ook over Thunderbolt 3 beschikt om een nog bredere selectie van aansluitingen te bieden. Een steviger toetsenbord zou de Lenovo ook helpen om de sponzige type-ervaring te verbeteren tot een niveau dat meer past bij de meeste Ultrabooks.
Het grootste nadeel van de snellere processor is het ventilatorgeluid. De ventilator is iets luider dan de Surface Pro en zal vaker opspinnen bij dagelijkse taken. Het geluid wordt niet zo hoog als de HP Spectre-series convertibles, maar is toch duidelijk aanwezig, zeker bij gebruik als tablet.
De Miix 520 is een erg goede aankoop zolang kopers zich bewust zijn van de nadelen. De snelle CPU zorgt voor een hoger systeemgeluid en vaker duidelijk hoorbare ventilator. We hopen dat toekomstige versies het beeldscherm verbeteren en inclusief Thunderbolt 3 geleverd worden. Zo kan de Miix-serie nog beter concurreren met Microsoft.
