Kort testrapport Dell Latitude 7390 (i5-8350U, SSD 256 GB) Laptop

Sven Kloevekorn, 14-04-2018

Slimme zaken. Dell update zijn zakelijke subnotebooks in de 7000-serie met de huidige Kaby Lake-R(efresh) processoren en heeft de 7390 naast andere beveiligingsfeatures uitgerust met een smart card slot. Ons testrapport bepaald of naast de erg lange batterijlevensduur het beeldscherm, de aansluitingen en de invoerapparaten ook voldoen aan de eisen van een zakelijke gebruiker.

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
35.2 ms ... stijging ↗ en daling ↘ gecombineerd↗ 21.2 ms stijging
↘ 14 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. » 90 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (26.2 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
48.8 ms ... stijging ↗ en daling ↘ gecombineerd↗ 24.8 ms stijging
↘ 24 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. » 80 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (41.9 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: 54 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 10374 (minimum: 43 - maximum: 588200) Hz waargenomen.

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

Met de nieuwe Latitude 7390, heeft Dell bijna alles goed gedaan. Voor een niet zo forse € 1400 die ons testmodel kost, ontvang je een goed gebalanceerd product met slecht enkele minpunten.

We moeten het ietwat kleine maar verder erg prettige toetsenbord benoemen, de matige touchpad toetsen, het ontbreken van Thunderbolt 3 en de luide spatie-toets. Het is een kleine ontwerpfout dat de deksel de basiseenheid optilt bij een openingshoek vanaf ongeveer 135°. Het enige dat we echt niet waarderen is het erbarmelijke geluidssysteem en de suboptimale vingerafdruksensor.

Niet alleen zijn er meer pluspunten te benoemen, dit zijn ook belangrijkere punten. Het kan gesteld worden dat met de i5-8350 de Latitude een onredelijk overschot aan rekenkracht heeft  voor simpele kantoortaken, maar omdat de batterijlevensduur hier geen last van heeft kan de extra rekenkracht zeker geen kwaad. Het simpel ontworpen maar hoge bouwkwaliteit behuizing, de goede tot erg goede invoerapparaten, de uitgebreide beveiligingsfeatures, de verstandige aansluitingen, het hoge contrast beeldscherm, Windows 10 Pro en tot slot 3 jaar fabrieksgarantie komen allemaal in een stil werkend apparaat dat duidelijk aangeraden kan worden.
