Using SVGA to output to DVI on my TV?

    I am trying to use an old VGA graphics card to output to DVI on a TV. The TV's manual seems to show that you can only output from an HDMI port, but I've been using an adapter to convert from VGA to DVI. Is there any way I can get a signal, or would I have to use a graphics card with an HDMI port? If it makes any difference, the card is an onboard Intel 82945G and the TV is a Samsung PN42C430A1D. Thanks in advance.

    In theory, it's possible. In reality, the video quality will be (at best) marginal. On a 42" HD set, I think you'll end up with flashbacks to a 1970's VHS player. :puke

    If your PC has a PCI-E 2.0 video card slot, spend a few extra bucks and get an entry-level NVIDIA card (such as the 210) that has a true HDMI out. Stick with NVIDIA as ATI is still having some driver issues on Intel-based boards.

    The good news is you should be able to find incredible deals. Last week I picked up an EVGA 210 (512MB DDR2 with VGA, DVI and HDMI outputs) at Fry's - Regular $49.99; Sale Price $34.99 less $20 mail-in rebate: Net price (including the cost of sales tax and a postage stamp): Under $20. With Black Friday fast approaching, you should see deals like this online at Newegg or Frys.com.

    Also, don't get ripped off on an HDMI cable. For a setup like this you don't need to spend a "Monster" amount for a $40+ cable. In Houston, Fry's retail stores have a generic 7' HDMI cable on sale for 4 (yes, four) dollars - I've used these and frankly can't see any picture quality difference. If you can't find HDMI cables under $10 locally; hit either NewEgg, Amazon or eBay.

    Good luck on the upgrade. :)

    Gman863: video quality isn't really a concern for now. You say that it would be possible to get some kind of output? Howso?

    Thanks for the help guys.

    See pclover's response (above) for the adapter type.

    Depending on your DVI output, you may have to run separate audio cables. The DVI to HDMI adapter won't always convert both audio and video. If this happens, you may have to run the audio directly to your stereo/home theater device; most HDMI TV inputs don't offer the option for a separate audio feed into an HDMI input.

    Another possibility is to find a DVI to Component Video adapter (Red/Green/Blue RCA video inputs plus Red/White RCA audio inputs). Most HD TVs have at least one component video input. This will give you picture quality at about 90% of an HDMI cable, avoid the separate audio hassles and avoid the copy protection gremlins that sometimes lurk in digital video content.
