Horisontaalsagedus

Lisa

Kuvari ekraanil kuvatavad tähemärgid ja pildid koosnevad paljudest punktidest (pikslid). Piksleid edastatakse horisontaalridadel, mis seejärel korrastatakse vertikaalselt, et luua pilti. Horisontaalsagedust mõõdetakse ühikuga kHz ning see tähistab, kui mitu korda sekundis edastatakse ja kuvatakse horisontaalridu kuvari ekraanil. Horisontaalsageduse näitaja 85 tähendab, et pildi moodustuvaid horisontaalridu edastatakse 85 000 korda sekundis ning horisontaalsagedust tähistatakse ühikuga 85 kHz.

Vertikaalsagedus

Üks pilt koosneb paljudest horisontaalridadest. Vertikaalsagedust mõõdetakse ühikuga Hz ning see tähistab, kui mitu pilti saab luua sekundis eelmainitud horisontaalridadega. Vertikaalsageduse näitaja 60 tähendab, et pilti edastatakse 60 korda sekundis. Vertikaalsagedust nimetatakse ka „värskendussageduseks” ja see mõjutab ekraani värelust.

Eraldusvõime

Eraldusvõime on ekraani moodustavate horisontaal- ja vertikaalpikslite arv. See kujutab monitori detailsuse taset.

Kõrgem eraldusvõime kuvab ekraanil rohkem teavet ja on sobilik mitme toimingu teostamiseks samaaegselt.

Näiteks eraldusvõime 1920 x 1080 koosneb 1920 horisontaalpikslist (horisontaalsagedus) ja 1080 vertikaalreast (vertikaalne eraldusvõime).

Plug & Play

Funktsioon Plug & Play võimaldab kuvari ja lauaarvuti vahel automaatselt teavet vahetada, et luua optimaalne kuvakeskkond.

Monitor kasutab funktsiooni Plug & Play käivitamiseks rahvusvahelist standardit VESA DDC.
