Kort testrapport Xiaomi Mi Notebook Pro i5 Laptop (Preview)

J. Simon Leitner (vertaald door Siemon Boes), 08-11-2017

Wiens uitvinding is het? Het is inmiddels een traditie geworden om gelijkenissen met Apple's designs te spotten in de producten van andere fabrikanten. Vooral Chinese merken gaan hier soms ver in. Met de Mi Notebook Pro volgt Xiaomi in de voetsporen van Apple's MacBook Pro - of toch wat uiterlijk betreft. Voor een prijs van minder dan 1000 euro (~$1160) biedt het toestel een aantrekkelijk totaalpakket met een quad-core-CPU, dedicated grafische kaart en een elegante aluminium behuizing. Maar wat schuilt er aan de binnenkant?

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

↘ 14.5 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 240 (maximum) ms. » 86 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (26.6 ms) van alle geteste toestellen.

Ter vergelijking: alle testtoestellen variëren van 0.9 (minimum) tot 636 (maximum) ms. » 76 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (42.6 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 21800 Hz99 % helderheid instelling

Het backlight van het scherm flikkert aan 21800 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 21800 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: 55 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 9418 (minimum: 43 - maximum: 247500) Hz waargenomen.

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

Wat we tot nu toe hebben gezien van de Xiami Mi Notebook Pro maakt een erg positieve indruk. Het design en de bouwkwaliteit zijn van een hoog niveau. Invoerapparatuur, scherm en prestaties zijn voor stuk voor stuk prima, emissies zijn onproblematisch en goede batterijduur is de kers op de taart. Niettemin is het nog wat vroeg om conclusies te trekken.

In de komende dagen zullen we onze tests voortzetten om probleemgebieden te vinden in de Chinese laptop. Tot nu toe zijn deze alleszins zeldzaam geweest: er is slechts één Type-C-poort om op te laden en de SD-kaartlezer presteert zwak. We zijn vooral benieuwd hoe de combinatie van quad-core ULV-CPU en GeForce MX150 het ervan af zal brengen bij het spelen van games.
