Sven Kloevekorn (vertaald door Siemon Boes), 26-08-2017

Surface-concurrent met AMOLED. Samsung zet de aanval in met zijn nieuwe Galaxy Book 12 en is erin geslaagd een uniek verkoopargument aan te bieden op de markt van de professionele Windows-tablets met een toetsenbord-cover: een Super-AMOLED-scherm. Het prijzige toestel biedt reizende businessmannen en -vrouwen een volledig totaalpakket met een grote variëteit aan accessories en slechts een aantal zwaktes.

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
20 ms ... stijging ↗ en daling ↘ gecombineerd↗ 18 ms stijging
↘ 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. » 13 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd beter is dan het gemiddelde (26.7 ms) van alle geteste toestellen.
       Responstijd 50% Grijs naar 80% Grijs
4 ms ... stijging ↗ en daling ↘ gecombineerd↗ 2 ms stijging
↘ 2 ms daling
Het scherm vertoonde erg snelle responstijden in onze tests en zou zeer geschikt moeten zijn voor snelle games.
Ter vergelijking: alle testtoestellen variëren van 0.9 (minimum) tot 636 (maximum) ms. » 1 % van alle toestellen zijn beter.
Dit betekent dat de gemeten responstijd beter is dan 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 250 Hz100 % helderheid instelling

Het backlight van het scherm flikkert aan 250 Hz (hoogstwaarschijnlijk met PWM - Pulse-Width Modulation) aan een helderheid van 100 % en lager. Boven deze helderheid zou er geen flickering / PWM mogen optreden.

De frequentie van 250 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: 57 % van alle geteste toestellen maakten geen gebruik van PWM om de schermhelderheid te verlagen. Als het wel werd gebruikt, werd een gemiddelde van 6285 (minimum: 43 - maximum: 142900) Hz waargenomen.

Potentiële kopers met genoeg cash kunnen nauwelijks verkeerd gaan als ze voor de Samsung Galaxy Book 12 LTE kiezen, tenminste als ze overtuigd zijn door het afneembare toetsenbord en de hoge mobiliteit. Afgezien van de magere selectie aan poorten is Samsung er met glans in geslaagd om het beste van twee werelden te combineren in één toestel.

S-Pen en toetsenbord zijn inbegrepen in de doos, evenals de slim ontworpen en perfect gefabriceerde tablet.

Hoewel het Super-AMOLED-scherm neit perfect is, kan het met zijn uitstekende zwartwaarden en contrast beschouwd worden als een uniek verkoopargument van de nieuwe convertible. Ons testtoestel was uitgerust met LTE en voldeed aan alle vereisten voor mobiliteit, inclusief GPS/GLONASS, TPM, BitLocker op Windows 10 Pro en uitstekende batterijduur. Kantoor- en zakelijke gebruikers zullen erg tevreden zijn met de goede invoerapparatuur, terwijl de camerakwaliteit goed genoeg is om meer dan een leuke extra te zijn.

Het feit dat Samsung een stille koeling en aanvaardbare temperaturen heeft verkozen boven volle performance onder aanhoudende belasting, zou niet merkbaar mogen zijn, zolang het toestel echter voor zijn beoogde doel wordt gebruikt - als een kantoortoestel. Daarom kunnen we het toestel voor dit gebruik zonder twijfel aanbevelen.
