-- Horisontaalsagedus

Ühe rea skannimiseks ekraanil vasakult paremale kuluvat aega nimetatakse horisontaaltsükliks. Horisontaaltsükli pöördväärtust nimetatakse horisontaalsageduseks. Horisontaalsagedust mõõdetakse kilohertsides (kHz).

-- Vertikaalsagedus

Vaatajale pildi näitamiseks kuvab seade ühte pilti mitu korda sekundis (nagu luminofoortuli). Üksiku

pildi kuvamise kordi sekundis nimetatakse vertikaalsageduseks ehk värskendussageduseks. Vertikaalsagedust mõõdetakse hertsides (Hz).

――Selle toote igale ekraanisuurusele saab paneeli omapära tõttu määrata parima pildikvaliteedi saavutamiseks ainult ühe eraldusvõime. Mõne muu kui kindlaksmääratud eraldusvõime kasutamine võib pildikvaliteeti halvendada. Selle vältimiseks on soovitatav valida teie seadmele kindlaksmääratud optimaalne eraldusvõime.

Kui vahetate arvutiga ühendatud CDT-seadme LCD-seadme vastu, kontrollige sagedust. Kui LCD-seade ei toeta 85 Hz, muutke CDT-seadet kasutades vertikaalset sagedust 60 Hz-ni, enne kui vahetate selle LCD-seadme vastu.

Ekraani reguleeritakse automaatselt, kui arvutist edastatakse järgmistele standardsignaalrežiimidele kuuluv signaal. Kui arvutist edastatav signaal ei kuulu standardsignaalrežiimide hulka, võib ekraan olla tühi ja toite LCD-tuli sisse lülitatud. Sellisel juhul muutke sätteid vastavalt järgmisele tabelile, vaadates graafikakaardi kasutusjuhendit.
