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 | ||
|---|---|---|
| 38 ms ... rise ↗ and fall ↘ combined | ↗ 8 ms rise |  |

| 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. » 95 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms). | ||

| 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. » 97 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 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 not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8705 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Blade Stealth injicerar en stor dos av Razers signatur i det ultratunna segmentet. Bygget utstrålar karaktär på ett sätt som gör "vanliga" ultrabooks från tillverkare som Lenovo och Dell gröna av avund. Dessutom har Razer introducerat individuellt bakgrundsbelysta tangenter på ett sätt som förmodligen ingen annan tillverkare kommer att göra.
Ser man bortom estetiken hittar man ett kvalitetschassi som lätt matchar vad vetererna erbjuder i storleksklassen. Skärmen är i en klass för sig, eftersom den har starkare bakgrundsbelysning och djupare färger än så gott som alla sina nuvarande konkurrenter.
Det som håller tillbaka den i toppstriden är den medelmåttiga batteritiden och tangentbordets feedback. Andra 12- och 13-tumsalternativ på marknaden kan lätt överleva Blade Stealth på en laddning. Tangenterna har för litet djup och klen feedback i jämförelse med t.ex. XPS 13, MacBook 12, och Yoga 900.
När det gäller prestandan uppskattar vi det faktum att systemet inte stryps under hög belastning. Det reducerar heller inte prestandan under batteridrift. Naturligtvis har en ULV-processor med dubbla kärnor begränsningar, så användare som ställer höga krav på multi-tasking, videoredigering m.m. får leta vidare.
Prislappen, som börjar på 1000 USD, innebär att Blade Stealth är förvånansvärt konkurrenskraftig i segmentet. Vi skulle faktiskt rekommendera en billigare modell för att undvika skalningsproblem och pressa ut längre batteritid ur datorn än vår 4K-testmodell.
