Clock
The analog input monitor needs to reproduce a clock of the same frequency as the dot clock of the graphics system in
use,whentheanaloginputsignalisconvertedtoadigitalsignalforimagedisplay.
Thisiscalledclockadjustment.Iftheclockpulseisnotsetcorrectly,someverticalbarsappearonthescreen.
DDC/CI (Display Data Channel/Command Interface)
VESAprovidesthestandardizationfortheinteractivecommunicationofthesettinginformation,etc.betweenaPC
andthemonitor.
DVI (Digital Visual Interface)
DVIisadigitalinterfacestandard.DVIallowsdirecttransmissionofthePC’sdigitaldatawithoutloss.
ThisadoptstheTMDStransmissionsystemandDVIconnectors.TherearetwotypesofDVIconnectors.Oneis
aDVI-Dconnectorfordigitalsignalinputonly.TheotherisaDVI-Iconnectorforbothdigitalandanalogsignal
inputs.
DVI DMPM (DVI Digital Monitor Power Management)
DVIDMPMisadigitalinterfacepower-savingfunction.The“MonitorON(operatingmode)”and“ActiveOff
(power-savingmode)”areindispensableforDVIDMPMasthemonitor’spowermode.
Gain
Thisisusedtoadjusteachcolorparameterforred,greenandblue.AnLCDmonitordisplaysthecolorbythelight
passingthroughthepanelcolorlter.Red,greenandbluearethethreeprimarycolors.Allthecolorsonthescreen
aredisplayedbycombiningthesethreecolors.Thecolortonecanbechangedbyadjustingthelightintensity(volume)
passingthrougheachcolor’slter.
Gamma
Generally, the monitor brightness varies nonlinearly with the input signal level, which is called “Gamma
Characteristic”.Asmallgammavalueproducesalow-contrastimage,whilealargegammavalueproducesahigh-
contrastimage.
HDCP (High-bandwidth Digital Contents Protection)
Digitalsignalcodingsystemdevelopedtocopy-protectthedigitalcontents,suchasvideo,music,etc.Thishelps
to transmit the digital contents safely by coding the digital contents sent via DVI terminal on the output side and
decodingthemontheinputside.
Any digital contents cannot be reproduced if both of the equipments on the output and input sides are not applicable
toHDCPsystem.
Phase
Phasemeansthesamplingtimingtoconverttheanaloginputsignaltoadigitalsignal.Phaseadjustmentismadeto
adjustthetiming.Itisrecommendedthatphaseadjustmentbemadeaftertheclockisadjustedcorrectly.
Range Adjustment
Rangeadjustmentcontrolsthesignaloutputlevelstodisplayeverycolorgradation.Itisrecommendedthatrange
adjustmentbemadebeforecoloradjustment.
Resolution
TheLCDpanelconsistsofnumerouspixelsofspeciedsize,whichareilluminatedtoformimages.Thismonitor
consistsof1920horizontalpixelsand1200verticalpixels.Ataresolutionof1920x1200,allpixelsareilluminated
asafullscreen(1:1).
