Gefendeliversinnovative,progressivecomputerandelectronicsadd-onsolutions
thatenhanceintegration,extension,distributionandconversiontechnologies.
Gefen’sreliable,plug-and-playproductssupplementcross-platformcomputer
systems,professionalaudio/videoenvironmentsandHDTVsystemsofallsizes
withhard-workingsolutionsthatareeasytoimplementandsimpletooperate.
The Gefen VGA Audio to HDMI Scaler
ConvertPCaudio/videotofull-screenHDMIwithsimultaneousanalog&digital
audiooutput.
UpscaleananalogvideosignalfromacomputerorVGAsourcetoahighquality
digitalHDdisplay.TheGefenVGAAudiotoHDMIScalersupportsarangeof
videoresolutionsupto1080p.Also,itwilltakedigitalTOSLINKoranalog3.5mm
mini-Stereoaudioasinput,andsimultaneouslyoutputtheaudiosignalinthe
sameformat.Acomprehensiveon-screendisplay(OSD)menuallowsintuitive
controloverarangeofA/Voperations.
How It Works
ConnectaVGAsourcetotheScalerinputwithaVGAcable.Next,connect
theanalogordigitalaudioinput/outputportsusing3.5mmmini-Stereocable.
ConnectTOSLINKoutputfromadigitalaudiosourcetoTOSLINKinputonthe
ScalerusingTOSLINKcable.Finally,connectanHDMI-compliantdisplaytothe
theHDMIoutputport.AudiosignalspasstotheamplierfromtheScalerthrough
theaudiocables,takingeitheranalogordigitalaudioandembeddingitintothe
HDMIoutput.
PoweruptheScalerbyplugginginthe5VDClinefromthepowersupply.Aclear
picturewillbedisplayedonthedisplay.

What Is Native Mode?

TheNativeModeofadisplayisasinglexedresolution.Thisresolution
representstheoptimaldisplayqualityatwhichadisplaycandisplayapicture.
ThiscanonlyoccurwhentheinputmatchestheNativeResolutionofthedisplay.
Notethatinordertoviewthescaledoutput,thedisplaymustbeabletosupport
thatresolution.Ifthedisplaydoesnotsupporttheoutputresolution,thedisplay
