Kako kontrolirati razinu svjetline u sustavu Windows 10

Svjetlinom monitora možete upravljati putem prozorafunkcijske tipke na tipkovnici. Kada dodirnete ili tipke za povećanje ili smanjenje svjetline, Windows 10 smanjuje svjetlinu za određenu razinu. Nema načina za kontrolu razine svjetline kada koristite namjenske tipke. Ako želite finiju kontrolu, morat ćete koristiti klizač svjetline. Ako želite kontrolirati razinu svjetline kada mijenjate svjetlinu na tipkovnici, to možete učiniti pomoću skripte za AutoHotkey.

ALTER SPOILERA: Pomaknite se prema dolje i pogledajte video vodič na kraju ovog članka.

Razine povećanja svjetline

Provjerite je li na vašem sustavu instaliran AutoHotkey.

Otvorite bilježnicu i u nju zalijepite sljedeće. Ovu skriptu napisao je korisnik Reddita yet_another_usr.

Na kraj ovog lijepa zalijepite sljedeće. Ovo je dio skripte koji ćete izmijeniti u skladu sa svojim potrebama. Sljedeće mijenja svjetlinu tipkama Page Up i Page Down na tipkovnici. Mijenja ga za 10, tj. Kada jednom dodirnete tipku Page Up, svjetlina se povećava za deset razina.

Uredite razine na ono što vam treba. Na primjer, možete ga promijeniti u 1 i -1 da biste dobili finiju kontrolu nad svjetlinom.

BS := new BrightnessSetter()
PgUp::BS.SetBrightness(10)
PgDn::BS.SetBrightness(-10)

Spremite skriptu s proširenjem datoteke AHK i pokrenite je. Upotrijebite tipke koje ste postavili za podešavanje svjetline.
