If I use a DVI to HDMI cable from my PC to TV will it have video and sound?

by on Apr.22, 2010, under Uncategorized

or can DVI not do sound as well? will it mess up?
Will there still be picture though? and can I just use different speakers. I heard it makes a funny noise like squealing ?

No.

There is no standard in the DVI specification for sound.

There should be picture, although some TVs can be very picky about what signals they will accept. You may want to have a monitor there that you can hot plug until you find the resolution and refresh rate that the TV is happy with.

    No, DVI doesn’t do sound. You need a HDMI to HDMI, or use computer speakers and put them next to your TV thats what I do. Or you can get an adapter and hook up the red, white, yellow cables to your TV, put them through an adapter, and connect HDMI, USB, or SVIDEO to your PC.

    DVI to HDMI does not carry sound. It requires a separate cable from the sound card to the TV.

    nVidia approaches HDMI audio differently from ATI. They use a SPDIF passthough. In my 9800GTX box I got a 2pin SPDIF cable, connects from the motherboard header to the 2pin header on the graphics card. You hook those up, plug in the DVI to HDMI adapter, and then in Windows change your default audio device to the SPDIF output.

    For ATI to use HDMI audio, the HD2000 series and newer have a built in HDMI 5.1 audio processor
    (7.1 on HD4000 series and newer). This requires you to install an audio driver, and set the windows audio device to be the HDMI audio output. I recall with the HD2900 series, the ATI installer did this by default and there were complaints that ATI drivers borked audio (no sound coming from speakers)
