Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 250 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 250 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 250 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 17803 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

På den positiva sidan av fördel/nackdel-listan har detta misslyckade försök till en kontorslaptop ändå riktigt bra inmatningsenheter och väldigt bra batteritid. På så sätt levererar Dell Latitude 15 3590 på sina utlovade proffsambitioner. Detta gäller också det inkluderade säkerhetspaketet och de företagsorienterade anslutbarhetsalternativen. Chassit imponerar också.
Det som däremot är oacceptabelt på en enhet för 8.000 kronor är skärmen, som är förskräcklig på alla sätt som kan tänkas. Det är en TN-skärm med horribla betraktningsvinklar, miserabel kontrast, en skarp blå ton vid leverans och ett riktigt lågt färgomfång. Utöver detta kommer en undermålig kortläsare, påtagligt dålig WLAN-prestanda och en fläkt som konstant tjuter i bakgrunden trots att datorn knappt är under belastning alls. Detta beror utan tvekan på den oanvändbara fläktprofilen och fläktkontrollen, som resulterar i helt kaotiska klockfrekvensbeteenden och massiv sporadisk strypning vid belastning.
Det är inte utan att man undrar vad Dell tänkte när de släppte denna i princip ofärdiga dator. Vår rekommendation är tydlig: Undvik!
Det skulle faktiskt vara en utmaning att hitta en mindre elegant och sämre utvecklad kontors/företagslaptop i det här prisskiktet.
