OSD (On Screen Display)

OSD (engl. On Screen Display – zaslonsko sučelje) omogućuje konfiguriranje zaslonskih postavki radi odgovarajuće optimizacije kvalitete slike. Omogućuje promjenu svjetline, nijanse i veličine zaslona te mnogih drugih postavki putem izbornika na zaslonu.

Gamma

Izbornik Gamma omogućuje prilagodbu razine sive boje koja na zaslonu predstavlja srednje tonove. Prilagodbom svjetline posvjetljava se čitav zaslon, dok se prilagodbom postavke Gamma posvjetljava samo srednja svjetlina.

Razina sive

Razina se odnosi na stupnjeve intenziteta boje koji variraju promjenama boje između tamnijih i svjetlijih područja na zaslonu. Promjene svjetline zaslona izražene su varijacijama crne i bijele, a razina sive odnosi se na srednje područje između te dvije boje. Promjenom razine sive boje putem postavke Gamma mijenja se srednja osvijetljenost na zaslonu.

Frekvencija skeniranja

Frekvencija skeniranja ili frekvencija osvježavanja odnosi se na brzinu kojom se slika na zaslonu obnavlja. Zaslonski podaci neprestano se osvježavaju radi prikaza slike, ali je to osvježavanje nevidljivo golom oku. Broj osvježavanja zaslona naziva se frekvencija skeniranja i izražava se u hercima (Hz). Frekvencija skeniranja od 60 Hz znači da se zaslon osvježava 60 puta u sekundi. Frekvencija skeniranja zaslona ovisi o performansama grafičke kartice u računalu i monitoru.

Vodoravna frekvencija

Znakovi ili slike koji se prikazuju na zaslonu monitora sastoje se od mnoštva točkica (piksela). Pikseli se prenose u vodoravnim crtama, koje se zatim okomito raspoređuju da bi se stvorila slika. Vodoravna frekvencija mjeri se u kilohercima (kHz), a upućuje na to koliko se puta vodoravne crte u sekundi prenose i prikazuju na zaslonu monitora. Okomita frekvencija od 85 kHz znači da se vodoravne crte od kojih se sastoji slika prenose 85 000 u sekundi.

Okomita frekvencija

Jedna se slika sastoji od mnoštva vodoravnih crta. Okomita frekvencija mjeri se u hercima (Hz), a upućuje na to koliko slika u sekundi mogu stvoriti te vodoravne crte. Vodoravna frekvencija od 60 Hz znači da se slika prenosi 60 puta u sekundi. Okomita frekvencija poznata je i pod nazivom "brzina osvježavanja" i utječe na titranje zaslona.
