Kort testrapport Dell Latitude 7390 2-in-1 (i7-8650U, FHD) Convertible

Professionele convertible… Er valt veel te waarderen aan de Latitude 7390 2-in-1, waaronder de Core i7-8650U quad-core CPU, NVMe SSD, stevige en compacte behuizing en de tweevoudige opslagstations. Echter, het apparaat heeft ook zo z'n gebreken - en de prijs ligt nogal hoog.

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↗ 16.4 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. » 77 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (25.8 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
48.8 ms ... stijging ↗ en daling ↘ gecombineerd↗ 23.6 ms stijging
↘ 25.2 ms daling
Het scherm vertoonde trage responstijden in onze tests en is misschien te traag voor games.
Ter vergelijking: alle testtoestellen variëren van 0.9 (minimum) tot 636 (maximum) ms. » 81 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (41.3 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: 53 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 8813 (minimum: 43 - maximum: 142900) Hz waargenomen.

Pro

+ Stevige, aantrekkelijke behuizing
+ Zeer goede invoerapparaten
+ Goede algehele systeemprestaties
+ Relatief eenvoudig onderhoud
+ Geweldig aanbod van poorten
+ Kleine afmetingen
+ Kan twee opslagstations bevatten (2x M.2 SSD)

Contra

- Core i7 optie biedt buiten single-core taken weinig voordelen
- Machine is topzwaar door de dikke beeldschermdeksel
- Beeldscherm is uiterst weerspiegelend
- Matige kleurdekking en -nauwkeurigheid
- Nogal zwaar voor z'n grootte
- Bruikbaarheid als convertible in typische zakelijke omgevingen blijft discutabel

De Latitude 7390 2-in-1 is een degelijke, aantrekkelijke notebook met zeer goede invoerapparaten en goede algehele systeemprestaties. Het apparaat biedt ook geweldige verbindingsmogelijkheden, eenvoudig onderhoud en een verrassend kleine voetafdruk. Ook de optie voor dubbele opslag is indrukwekkend, aangezien de vrije WWAN slot ook door een M.2/NVMe 2230 SSD kan worden gebruikt. Echter, hoewel CPU prestaties enigszins beter zijn dan concurrerende apparaten, is het kiezen van een Core i7 configuratie lastig te rechtvaardigen. Tenzij het gebruik voornamelijk zal bestaan uit het draaien van single-thread applicaties, raden wij je aan om te kiezen voor de goedkopere Core i5 configuratie.

De Latitude 7390 2-in-1 is een degelijke, aantrekkelijke notebook met zeer goede invoerapparaten en goede algehele systeemprestaties. Echter, het apparaat kent enkele nadelen en is zeker geen kleine investering. Voordat je overgaat tot aankoop, kijk eerst eens bij de concurrentie!

De 7390 2-in-1 wordt geplaagd door enkele andere nadelen. Er zijn uitsluitend glanzende touchscreens beschikbaar als beeldscherm en geen van die modellen presteert het om wat betreft kleurreproductie in de buurt te komen van topmodellen zoals de ThinkPad X1 Carbon. De geteste NVMe SSD kon modellen van Samsung nauwelijks bijhouden. Het apparaat is nogal zwaar voor z'n grootte en vanwege het zware beeldscherm staat de laptop minder stabiel dan we graag zouden zien. Tenslotte rest de vraag of zakelijke gebruikers écht behoefte hebben aan de convertible-functies van dit soort apparaten. Dell heeft namelijk al een perfect capabele, extreem goed gebalanceerde 'normale' Latitude 7380 (en hopelijk ook de nog te testen 7390). Ook kan de normale variant uitgerust worden met ontspiegeld glas, is het apparaat lichter en voelt hij stabieler.

Andere apparaten die het overwegen waard zijn (afgezien van de conventionele Latitude 7380/7390) zijn de uitstekende ThinkPad X1 Carbon 2018 en Asus Zenbook 13 UX331UA. Met een adviesprijs van $2109 (zoals geconfigureerd) is de Latitude 7390 2-in-1 zeker geen kleine investering. Dus, voordat je overgaat tot aankoop, werp eerst eens een blik op de concurrentie!
