HMDI Conection i am not getting a signal through the HMDi conection, i have changed the lead and have checked the settings

No. HDMI cables use the RGB and sync on separate connection pins on the cable. RCA cables use the whole composite picture TV signal on the cable.

Hi,

What did you do to lose the HMDI output? How is everything exactly hooked up?

It's not a channel. You should select the input to TV to HDMI. Refer its user manual, please.

Hello,

Does your PC have either a DVI or HMDI video connector on either the motherboard or the graphics (video) card? (In other words somewhere on the back of the machine?)

Does your HD TV have a DVI or HMDI connector on it?

If the answer to both of these questions is yes then you can do it.

Most peoples first choice would be to use the HMDI connectors. If you wish to do this you will need an HMDI cable.

If you decide to use the DVI connectors then you will need a DVI cable.

If your PC doesn't have either the DVI or HMDI outputs then you will have to buy a graphics (video) card for you PC. Be sure to get the appropriate cable also.

Once you have the HD TV connected to your computer you will have to use the graphics card's software to set things up. If you right click in an empty area of the desktop this software should be one of the choices in the menu.

HTH

Do you have your ps3 connected to the TV with HDMI and then audo cables from the TV to the receiver? If so, you need to make sure you change the audio settings on your TV to surround sound.

u have to go on to the system settings wilst u av it on ur hd tv and change it from there

you have to right click on an empty space on your desktop and choose either graphics options or graphic properties and select the external monitor, it depends on the graphics chip fitted but they are all similair
