Kort testrapport LG Gram 17Z990 (i7-8565U. WQXGA) Laptop

Allen Ngo, 👁 Allen Ngo, 20-04-2019

Bijna zo licht als de XPS 13. De Gram 17 kraakt de trend dat 17.3-inch laptops groot en onhandig moeten zijn. Met slechts 1,34 kg is de laptop merkbaar lichter dan de meeste 14-inch en 15-inch Ultrabooks, terwijl hij veel van dezelfde functies biedt, waaronder Thunderbolt 3 en een lange batterijlevensduur.

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
31.2 ms ... stijging ↗ en daling ↘ gecombineerd↗ 18 ms stijging
↘ 13.2 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. » 79 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (25.4 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
42 ms ... stijging ↗ en daling ↘ gecombineerd↗ 20.4 ms stijging
↘ 21.6 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. » 53 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (40.5 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 niet waargenomen

Ter vergelijking: 51 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 9654 (minimum: 43 - maximum: 142900) Hz waargenomen.

Voor het volledige, Engelse testrapport, klik hier.

De LG Gram 17 is het beste voor gebruikers die een groot 17.3-inch scherm willen, maar verder geen behoefte hebben aan omslachtige formaten. Het apparaat is buitengewoon lichtgewicht en de batterij gaat lang mee om het een van de beste laptops in zijn grootteklasse voor reizigers te maken. Als je merkt dat de meeste Ultrabooks niet genoeg schermruimte bieden, dan zou de Gram 17 in je straatje moeten passen.

De prijs die je moet betalen voor zo'n lichte 17,3-inch laptop zal hoog zijn. Ondanks de metaallegering en MIL-STD 810G-specificaties is de Gram 17 bij lange na niet zo rigide als de XPS 15, Spectre x360 15 of zelfs de meeste andere Ultrabooks. Eigenaars moeten ervoor zorgen dat ze het kwetsbare deksel niet beschadigen wanneer ze onderweg zijn.

Andere opvallende nadelen zijn de softkeys en het clickpad, het lastige onderhoud, de matige audiokwaliteit en de ondergemiddelde Core i7-prestaties. LG had de prijs kunnen verlagen door een Core i5-optie en kleinere SSD te integreren zonder de algemene prestaties van het systeem te beïnvloeden. Voor $1500 kunnen gebruikers een stevigere en aanzienlijk snellere Dell XPS 15 aanschaffen. Als het grote 17,3-inch scherm u niet aanspreekt, bent u misschien beter af met een traditionele 13-inch of 15-inch Ultrabook.

Veel lichter dan andere kleinere Ultrabooks op de markt en biedt een groter 17,3-inch WQXGA-beeldscherm. LG heeft voor zichzelf een comfortabele niche gecreëerd in het relatief impopulaire 17-inch laptopsegment. De Gram 17 is een multimedia- en lichte kantoornotebook voor reizigers die het ruime 17,3-inch scherm willen ten volle gaan benutten.
