* Will I be able to use the Vizio as a monitor in its native 1080p resolution, and still get sound from my sound card?
* If so, what cables and adapters do I need to buy?
I'm pretty confused at this point. I get the impression that an HDMI-DVI adapter wouldn't work with my setup because you can't get sound without a SPDIF passthrough. Would using the HDTV's VGA connection and using a VGA-DVI adapter for the graphics card work? Would I need to connect anything to my soundcard? Can VGA handle 1080p resolution?
I would be extremely grateful for any help.
As a proof of confidence... I have 8800GT OC 512, GTX 280 OC both connected to HDTV (52 inch , 70 inch). Work like a charm @ 1080P through HDMI. Your card should do it.
For the Sound:
You can use Line-Level Output(Front) from your sound card to the Stereo Analog Input of your TV. Make sure to read the set-up manual of your TV to configure the audio source of the HDMI-Input to the Analog Stereo Input.
Connector to Purchase:
You need a 3.5mm to RCA (Audio SPlitter cable : Stereo).
Thanks for the response. Is the audio cable necessary to get sound, or optional? I'm guessing without the audio cable that when I watch TV, sound will come through the TV speakers, and when I watch a movie on my computer or play games, sound will come through my computer speakers, which is fine with me. Is that a correct assumption?
Nvidia Cards such as my GTX280OC have SPDIF connector to get audio from my sound card. In that way both Audio and Video goes through the HDMI cable.
I'm not sure if your EVGA 9800GT has an SPDIF input. For that to work you also need a SPDIF output from your Audio CARD. If these connectors are present then its possible to get audio and video through the HDMI connector.
If the above stated conditions are not met then you need the Audio cable from your video card to the TV to pass audio from PC-Audio card to your TV.
Note: This my presonal preference
I have 3 HDTV setup are home (52 and 2 70inch)..... Although my audio goes through HDMI i rarely use the Audio of my TV.
My PC(Games, Blue -Ray-Movie, HD-DVD-Movie, PC-HDDVR, PC-HDPVR), PS3(PS3 Games, Blue-Ray movie), DVD Player, SAT BOX... Are all connected to receivers with 7.1 speakers.
