Screen Flickering / PWM (Pulse-Width Modulation)
Screen flickering / PWM detected | 27000 Hz | ≤ 90 % brightness setting | |
The display backlight flickers at 27000 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 27000 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 8774 (minimum: 5 - maximum: 343500) Hz was measured. |

Acer Extensa 2540-580K kommer med en kraftfull CPU, en snabb SSD och RAM med stöd för dual-kanalsläge. Enheten blir inte varm oavsett belastning och är nästan helt tyst under körning. Extensa erbjuder därför funktioner och attribut som kan associeras med vanliga företags-laptops.
Med Extensa 2540 levererar Acer en väldigt tålig företagsenhet som kommer behöva hitta sin egna publik. Skärmen kommer vara en avgörande faktor för många potentiella köpare.
Som tur är har Acer utrustat denna laptop med en liten underhållslucka bakom dess SSD där RAM-platserna sitter. Det borde därför inte vara några problem att uppgradera dessa komponenter. Tangentbordet lämnade en i huvudsak "okej" upplevelse. Men vi hade väldigt gärna sett bakgrundsbelysning. Med det kunde Acer ha rundat av denna företagsenhet, vilket är vad Extensa är tänkt att vara. Den utmärkta batteritiden ger också denna laptop mer värde.
Dess största svaghet - som så ofta är fallet - är skärmen. Acer använder en mörk skärm med dålig kontrast och dåliga betraktningsvinklar, som inte ens hade känts lämplig i en modell för 4 000 kronor (400 Euro).
Med den här modellen riktar Acer i huvudsak in sig på professionella användare, därav den förinstallerade kopian av Windows 10 Pro. Pro-versionen ökar enhetens pris något, vilket får datorn att verka mindre lockande för genomsnittliga användare. Acer erbjuder inte ett alternativ med likvärdigt utrustad hårdvara men med Windows 10 Home istället. Extensa 2540-56GC ligger närmast vår recensionsenhet. Men den kommer bara med en HD-skärm (1366x768).
Uppdatering 13.12.2017: Acer har informerat oss om att modellen vi har testat i vår recension inte längre finns tillgänglig och har ersatts av den identiskt konstruerade modellen Extensa 2540-54C0.
