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
32 ms ... stijging ↗ en daling ↘ gecombineerd↗ 18 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. » 81 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd slechter is dan het gemiddelde (25.1 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
42 ms ... stijging ↗ en daling ↘ gecombineerd↗ 22 ms stijging
↘ 20 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. » 54 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd vergelijkbaar is met het gemiddelde (40.1 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 208 Hz ≤ 90 % helderheid instelling

Het backlight van het scherm flikkert aan 208 Hz (hoogstwaarschijnlijk met PWM - Pulse-Width Modulation) aan een helderheid van 90 % en lager. Boven deze helderheid zou er geen flickering / PWM mogen optreden.

De frequentie van 208 Hz is redelijk laag en de meeste mensen die gevoelig zijn aan flickering kunnen dit dus waarnemen of geïrriteerde ogen krijgen (gebruikmakend van de vermelde helderheid en lager).

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 9429 (minimum: 43 - maximum: 142900) Hz waargenomen.

De Dell Latitude 3390 is een redelijk geprijsde 13.3-inch zakelijke convertible. Ons testmodel heeft een Intel Core i5-8250U processor, 8 GB RAM en een 256 GB SSD, wat gezien de € 999 verkoopprijs een goede configuratie is. Samengevat is de Latitude 3390 in de configuratie die we getest hebben relatief goedkoop voor een zakelijk notebook en is het ook een fatsoenlijk alternatief voor consumenten notebooks. Helaas ontbeert het de notebook aan enkele belangrijke zakelijke features zoals optie tot LTE en beveiligingsfeatures zoals een vingerafdruksensor. De Latitude 3390 zal voor professionals dan ook minder aantrekkelijk zijn.

De quad-core Core i5-8250U is krachtig genoeg voor de meeste toepassingen, net als de 8 GB RAM. Beide zijn echter niet heel toekomstbestendig en geven de indruk dat Dell de Latitude 3390 een jaar te laat op de markt brengt. Het ontwerp draagt bij aan dat gevoel. Het simpele ontwerp zal er voor sommige mensen elegant uitzien, maar de dikke beeldschermranden zien er verouderd uit. Dell had de Latitude 3390 makkelijk met een 14-inch paneel kunnen uitrusten in dezelfde behuizing.

En als we het daar toch over hebben, het beeldscherm is een van de grote teleurstellingen van de Latitude 3390. Het is simpelweg te donker, waardoor buiten werken erg lastig wordt. Ook het kleurbereik is naar onze mening te laag voor een zakelijk notebook.

De Dell Latitude 3390 laat een dubbel gevoel achter. Het heeft geen unieke verkoopargumenten en voldoet niet helemaal aan de verwachtingen van een zakelijke convertible.

Er zijn ook pluspunten te benoemen. Dell heeft de Latitude 3390 gemaakt van gerecycled carbon fiber waardoor ons testmodel erg stevig aanvoelt. En tegelijkertijd wordt het gewicht onder de 1.6 kg gehouden. Het touchscherm, touchpad en toetsenbord zijn ook allen goed, hoewel deze laatste niet kan tippen aan de ThinkPad concurrentie. De Latitude 3390 is ook erg energiezuinig en heeft goede luidsprekers, maar dat zal waarschijnlijk vergeten worden zodra de minpunten van het beeldscherm opgemerkt worden.

The Dell Latitude 3390 is a reasonably priced 13.3-inch business convertible. Our review unit comes with an Intel Core i5-8250U processor, 8 GB of RAM and a 256 GB SSD, which makes it well equipped for its 999-Euro (~$1,130) retail price. In short, the Latitude 3390 in the configuration that we tested is comparatively cheap for a business device and is a decent alternative to consumer-grade laptops for private buyers too.

Unfortunately, the device lacks important business features like optional LTE connectivity and security features like a fingerprint sensor. Hence, the Latitude 3390 will probably prove an unattractive option for professionals.

The quad-core Core i5-8250U is powerful enough for most demanding tasks though, as is the 8 GB of RAM. However, they are not future-proofed and give the impression that Dell has brought the Latitude 3390 to market a year late. The design compounds this view too. The simple design will look elegant to some people, but the wide display bezels look outdated. Dell could have easily equipped the Latitude 3390 with a 14-inch panel within the same chassis.

While we are on the subject, the display is one of the big let-downs of the Latitude 3390. It is simply too dark, making outdoor use a chore. Likewise, the colour-space coverage is too low for a business device in our opinion.

The Dell Latitude 3390 leaves an ambiguous impression. It has no unique selling point and does not meet expectations of what a business convertible should be.

It is not all bad news though. Dell has built the Latitude 3390 with recycled carbon fibre, which makes our review unit feel sturdy. At the same time, it keeps the overall weight below 1.6 kg. The touchscreen, trackpad and keyboard are decent too, although the latter is not in the same league as its ThinkPad competitors. The Latitude 3390 is impressively energy-efficient too and has full-bodied speakers, but these are likely to be forgotten when people experience its display.
