Kort testrapport HP ProBook 440 G4 (Core i7, Full-HD) Notebook

Slecht scherm. HP's 14-inch business-laptop krijgt ook de Kaby Lake-update. Net als bij zijn grotere 15-inch-broer worden we echter niet overtuigd door het scherm.

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
24.4 ms ... stijging ↗ en daling ↘ gecombineerd↗ 7.2 ms stijging
↘ 17.2 ms daling
Het scherm vertoonde prima responstijden in onze tests maar is misschien wat te traag voor competitieve games.
Ter vergelijking: alle testtoestellen variëren van 0.8 (minimum) tot 240 (maximum) ms. » 42 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (24.2 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
43.2 ms ... stijging ↗ en daling ↘ gecombineerd↗ 21.2 ms stijging
↘ 22 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 636 (maximum) ms. » 62 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (38.4 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 9651 (minimum: 5 - maximum: 151500) Hz waargenomen.

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

De HP ProBook 440 G4 is erg gelijkaardig aan de verwante ProBooks, wat zowel positief als negatief is. Het is een instapmodel zakelijke machine, dus je zal een aantal toegevingen moeten doen. Een van die toegevingen heeft te maken met het ontbreken van features als de SmartCard-lezer of docking-poort. De ProBook wordt overtroffen door duurdere producten zoals HP's eigen EliteBook op het vlak van bouwkwaliteit en connectiviteit.

Het grootste probleem van de ProBook 440 G4 is echter het scherm. Ons testmodel is reeds uitgerust met het 'beste' scherm dat je kan krijgen voor dit systeem, maar toch worden we teleurgesteld. We begrijpen niet waarom HP zelfs geen IPS-paneel als optie aanbiedt en zelfs voor een TN-paneel is de kwaliteit redelijk ondermaats.

De HP ProBook 440 G4 is snel, heeft een goede behuizing en een comfortabel toetsenbord, maar het scherm valt moeilijk te verantwoorden voor meer dan 1000 euro.

De prestaties van de geüpdatete ProBook 440 G4 stellen niet teleur: het systeem kan bijna alle applicaties aan dankzij de snelle processor en SSD. Of je baat hebt bij de discrete GPU is een andere vraag. Deze chip is uiteraard krachtiger dan de geïntegreerde chip, maar dit is vooral merkbaar bij het spelen van games. Je kan zonder problemen een versie met een Core i5 en geïntegreerde grafische kaart kiezen als je wat geld wilt uitsparen. Toch blijft het door het teleurstellende scherm niet eenvoudig om de 15-inch-versie van de ProBook aan te bevelen voor alle gebruikers.
