Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White
33.4 ms ... rise ↗ and fall ↘ combined	↗ 13.2 ms rise
33.4 ms ... rise ↗ and fall ↘ combined	↘ 20.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 89 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
37 ms ... rise ↗ and fall ↘ combined	↗ 19 ms rise
37 ms ... rise ↗ and fall ↘ combined	↘ 18 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 49 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM detected

200 Hz

≤ 30 % brightness setting

The display backlight flickers at 200 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

Emot

- mottaglig för fingeravtryck

- relativt stort chassi i storleksklassen

- ingen SD-kortläsare

- PCIe-SSD lever inte upp till sin fulla potential

- mer feedback från tangentbordet hade varit bra

- testexemplaret lider av "coil whine"

In Review: Razer Blade Stealth with Intel Kaby Lake

Med den senaste uppdateringen av Blade Stealth har Razer eliminerat föregångarens största brist: den mediokra batteritiden. Nu håller den ut i upp till 13 timmar, så beroende på arbetsuppgifter kan batteriet räcka hela dagen.

Chassit är oförändrat. Designen håller definitivt hög klass och kan jämföras med Apples MacBook vad gäller byggkvalitet och haptik. Tyvärr är den mattsvarta ytan känslig för fingeravtryck, som dessutom kan vara mycket svåra att få bort.

Den här gången fick vi ett testexemplar med QHD+-panel, som nästan är i klass med 4K-alternativet – särskilt med tanke på storleken på 12,5 tum ser den här skärmen ut som det bättre alternativet i de flesta fall. Konfigurationen med den inte fullt så högupplösta panelen är dessutom ett par tusenlappar billigare och förbrukar sannolikt mindre ström.

Vi är också imponerade av prestandan. Processorn gör ganska bra ifrån sig även under kontinuerlig belastning. Blade Stealth bör ha tillräcklig kraft för att driva Razer Core-grafikkortet, vilket resulterar i ett riktigt spelsystem.

Sammanfattningsvis: Tack vare Kaby Lake-processorn och det större batteriet kan Blade Stealth numera mäta sig med konkurrenterna. Det externa GPU-chassit Razer Core är ett spännande alternativ, men Blade Stealth kan stå på egna ben även utan tillbehöret.
