Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 22730 Hz | ≤ 24 % brightness setting |  |
The display backlight flickers at 22730 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 24 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 22730 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Den senaste Blade Stealth har den största prestandaökningen i serien hittills. Den nya Whiskey Lake U-processorn är mindre känslig för strypning och dess diskreta GPU-alternativ har nästan samma spelprestanda som 2015 års version av Blade Pro. Den här datorn är beviset för att en Ultrabook kan leverera skaplig grafikprestanda utan att behöva offra nyckelfunktioner som lång batteritid, ultratunn design, skärm med god färgprecision eller tysta fläktar för icke-spelrelaterade applikationer. Den fungerar idealt för användning i klassrummet och sedan också för den där viktiga matchen Fortnite, Overwatch, Rocket League eller League of Legends efteråt. Konkurrerande Ultrabook-modeller med samma GeForce MX150 GPU som HP Envy 13t eller Huawei MateBook X Pro är 25 till 30 procent långsammare vid spelande.
De största bristerna rör tangentbordet och skärmen. Tangentspecifik RGB-belysning och HDMI saknas på den senaste generationen Blade Stealth. Det går fortfarande inte att uppgradera RAM och tangentbordet kunde haft djupare återkoppling. I synnerhet tar de förkortade Enter- och Backspace-knapparna lite tid att vänja sig vid. På samma gång är de svart-vita och grå-grå responstiderna medelmåttiga som bäst, vilket resulterar i en tydligare ghosting-effekt.
Vi upplevde också en handfull tekniska problem som vi hoppas bara rör vår testenhet. Den löst sittande laddningskabeln, ett lätt till måttligt elektroniskt ljud och ett batteri som laddas ur vid spelande även om AC-adaptern är ansluten är brister med en i övrigt kraftfull spel-ultrabook på 13.3 tum. Processorn hade också en del underligt klockfrekvens-beteende.
Prestandan per watt är helt galen för den här storleksklassen. Kraftigare än en MacBook Pro 13 utan att vara varken större eller tyngre: nya Blade Stealth är bättre än någonsin på att balansera hög prestanda med hög mobilitet.
