Terminologi

OSD (On Screen Display, visning på skærmen)

Med visning på skærmen (OSD) kan du konfigurere indstillinger på skærmen for at optimere billedkvaliteten efter behov. Dermed kan du ændre skærmens lysstyrke, tonfarve, størrelse og mange andre indstillinger med menuer, der vises på skærmen.

Gamma

I menuen Gamma kan du justere den gråtoneskal, der repræsenterer skærmens mellemtoner. Justering af lysstyrken gør hele skærmen lysere, men med justering med Gamma bliver kun den mellemste lysstyrke lysere.

Gråtoneskala

Skala angiver niveauet af farveintensitet, der viser variationer i farveændring fra mørkere områder til lysere områder på skærmen. Ændringer i skærmens lysstyrke udstyres med variation af sort og hvid, og gråtoneskala angiver mellemområdet mellem sort og hvid. Ændring af gråtoneskalaen ved justering af Gamma ændrer skærmens mellemste lysstyrke.

Skanderingshastighed

Skanderingshastighed, eller opdateringshastighed, angiver den frekvens, hvormed skærmen opdateres. Skærmdata transmitteres, når skærmen opdateres for at vise et billede, men opdateringen kan ikke ses med det blotte øje. Antallet af skærmopdateringer kaldes skanderingshastigheden og måles i Hz. En skanderingshastighed på 60 Hz betyder, at skærmen opdateres 60 gange i sekundet. Skærmens skanderingshastighed afhænger af ydeevnen af grafikkortene i computeren og skærmen.

Horisontal frekvens

Tegn eller billeder, der vises på skærmen består af en masse prikker (pixels). Pixels transmitteres i vandrette linjer, som derefter arrangeres lodret for at skabe et billede. Den vandrette frekvens måles i kHz og angiver, hvor mange gange de vandrette linjer transmitteres i sekundet og vises på skærmen. En vandret frekvens på 85 betyder, at de vandrette linjer, som et billede består af, sendes 85.000 gange i sekundet. Den vandrette frekvens angives i 85 kHz.

Vertikal frekvens

Et enkelt billede består af mange vandrette linjer. Den lodrette frekvens måles i Hz og angiver, hvordan mange billeder der kan vises i sekundet af disse vandrette linjer. En lodret frekvens på 60 betyder, at et billede transmitteres 60 gange i sekundet. Den lodrette frekvens kaldes også "opdateringshastigheden", og den påvirker, om skærmen flimrer.
