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
30.4 ms ... stijging ↗ en daling ↘ gecombineerd↗ 15.6 ms stijging
↘ 14.8 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. » 76 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (26.7 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
44 ms ... stijging ↗ en daling ↘ gecombineerd↗ 19.6 ms stijging
↘ 24.4 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. » 63 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (42.8 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 922.1 Hz20 % helderheid instelling

Het backlight van het scherm flikkert aan 922.1 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 922.1 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: 57 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 6272 (minimum: 43 - maximum: 142900) Hz waargenomen.

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

Met de Dell Latitude 7285 presenteert de fabrikant ons een erg hoge kwaliteit convertible met moderne componenten. De Intel Core i5-7Y57 biedt solide prestaties en kan alledaagse kantoorwerkzaamheden aan. De CPU kan ook multimedia toepassingen goed af. Op veel vlakken kan de zuinige SoC de snellere ULV processoren bijhouden. € 2.300 voor een apparaat met de uitrusting zoals we getest hebben is een behoorlijk bedrag. De klant krijgt daarvoor wel een foutloos geproduceerd apparaat, dat in alle opzichten high-end ademt.

De verkoopprijs mag initieel afschrikken, maar Dell biedt een erg goedgebouwd apparaat met eerste klas 3K beeldscherm en een aanbod van moderne aansluitingen. Behalve het tablet en het toetsenborddock, bevat het pakket ook de Dell Active Pen en een 36-maanden garantiepakket.

We waarderen de erg goede selectie van materialen en het ingetogen ontwerp. De Dell Latitude 7285 scoort erg goed met het beeldscherm, dat een erg hoge helderheid heeft en een groot kleurbereik. Eerlijk gezegd hadden we minder prestaties van de processor verwacht, maar omdat Dell zich niet beperkt tot het TDP van 4.5 watt zijn de prestaties iets hoger dan we verwacht hadden. Alle testresultaten tonen zonder uitzondering aan dat de Dell Latitude 7285, gebaseerd op de Intel Core i5-7Y57, de concurrentie bij kan houden.

Qua stroomverbruik stelt het apparaat ons wat teleur, omdat we door de zuinige componenten hoge verwachtingen hadden. Dit resulteert ook in gemixte batterijlevensduurresultaten. Het idee om een extra batterij in het toetsenbordock te plaatsen is goed en voorkomt een lagere plaats in onze vergelijkingen.
