Kort testrapport Chuwi LapBook Air 14.1 (N3450, FHD) Laptop

Allen Ngo, 01-11-2017

Aantrekkelijk en traag. Chuwi's MacBook Air kloon ziet er zeker goed uit en kan makkelijk doorgaan voor een twee keer zo duur Ultrabook. Wanneer je wat beter kijkt zie je echter al snel de nodige tekortkomingen.

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
29.2 ms ... stijging ↗ en daling ↘ gecombineerd↗ 16 ms stijging
↘ 13.2 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. » 69 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (26.6 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
32.8 ms ... stijging ↗ en daling ↘ gecombineerd↗ 12.8 ms stijging
↘ 20 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. » 19 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd beter is dan het gemiddelde (42.5 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 200 Hz20 % helderheid instelling

Het backlight van het scherm flikkert aan 200 Hz (hoogstwaarschijnlijk met PWM - Pulse-Width Modulation) aan een helderheid van 20 % en lager. Boven deze helderheid zou er geen flickering / PWM mogen optreden.

De frequentie van 200 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: 55 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 9257 (minimum: 43 - maximum: 247500) Hz waargenomen.

In review: Chuwi LapBook Air 14.1. Test model provided by Chuwi

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

De LapBook Air ziet en voelt fantastisch aan gezien de lage € 400 adviesprijs. Het 1080p IPS beeldscherm is scherp, het tweede slot voor interne opslag is zeldzaam en er is zelfs een verlicht toetsenbord. Helaas heeft de fabrikant zwaar moeten besparen op bijna alle andere vlakken om de onmogelijk lage adviesprijs te behouden.

Om te beginnen is de kwaliteitscontrole niet van hetzelfde niveau als de bekendere alternatieven. Ons testmodel heeft last van matige backlight bleeding, oneven verlicht toetsenbord, een gebroken Ctrl-toets, een kapotte USB-poort, meerdere crashes en een gebogen rand. We adviseren nieuwe gebruikers dan ook met klem om alle poorten en toetsen te testen om te controleren dat deze werken. Ten tweede is er de passief gekoelde Celeron processor, primaire SSD en stroomadapter, die allen uiterst langzaam zijn. Gebruikers die iets meer prestaties willen zijn beter af met een oudere ULV Haswell notebook die waarschijnlijk een steviger toetsenbord heeft en nauwkeuriger touchpad. Als het primaire doel is om te streamen en onderweg video's af te spelen, dan is de LapBook Air niet slecht.

De LapBook zou zijn nut moeten bewijzen voor diegenen die enkel willen browsen, tekstverwerken en streamen.
