Hi.. i am having a G2420HD benq LCD monitor ... there is an audiio jack connect to it on the side panel .. When i attach a headphone with the audio jack or the speakers there is no sound.why is that??any idea??

you got to connect your monitor with the motherboard's audio-out port.. the required cable should have been bundled with your monitor itself.. ..

plus there are settings to be done in control panel if you are running windows 7 i guess
thats what happened to my friend too
