Microsoft Surface Book 2 (13.5", i7, GTX 1050) Convertible rövid értékelés

Erőgép? A Microsoft szerint a Surface Book 2 két kategória legjobb tulajdonságait egyesíti magában, és az eddigi legerősebb Surface készülék. A specifikációi ígéretesnek tűnnek, hála a Kaby Lake-R processzornak és az Nvidia Pascal-os GPU-jának. Tesztünk rávilágít néhány hiányosságra – egy részükön könnyedén túl lehet lépni, de mások egyszerűen érthetetlenek ebben az árkategóriában.

Képernyő villogása / PWM (impulzusszélesség-moduláció)

A képernyő tompításához egyes notebookok egyszerűen be- és kikapcsolják a háttérvilágítást gyors egymásutánban - ez az úgynevezett impulzusszélesség-moduláció (PWM) módszer. Ennek a ciklikus frekvenciának ideális esetben az emberi szem számára nem észlelhetőnek kell lennie. Ha ez a frekvencia túl alacsony, az érzékeny szemű felhasználóknak megerőltető lehet, fejfájást okozhat, vagy akár észre is vehetik a villódzást.
Képernyő villogása / PWM nem érzékelhető

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured.

Megjelenítési válaszidők

A kijelző válaszideje azt mutatja, hogy a képernyő milyen gyorsan képes egyik színről a másikra váltani. A lassú válaszidők utóképekhez vezethetnek, és a mozgó tárgyak elmosódottak lehetnek (szellemképek). A gyors tempójú 3D-s címek játékosainak különösen oda kell figyelniük a gyors válaszidőkre.
