do dvi to component adapters work?

I got one to hook into my gf's tv, since she doesn't have hdmi or dvi in. I hooked it up to the component in and and it throws up a mangled picture then drops out, I have the vga connected so I can mess with it, but it doesn't even show up as a display option.

Do these adapters even work?
 
you cant do digital to anolog but you can do anolog to digital.. so DVI to component will not work..

now if the card has svideo you might be able to use an svid to component.. thats what i used with my ATI HD2600Pro on my tv which had svid..
 
her TV has composite, component, and s-video... is there any way to connect the computer to the TV?
 
The card has to have support for component out via the DVI port, you can't just connect an adapter to a card that didn't come with one (and doesn't have support for the feature) and expect it to work. You may have better luck with a VGA to component adapter. The TV has a VGA port? Find some documentation and try to get that working. What kind of TV / how old is it?
 
no, I wish the TV had VGA support!

It's a tube tv, probably 5 years old or so. It has inputs for composite, component, and s-video.... The video card is an igp 4200 with dvi, hdmi, and vga outs.

Your cheapest option would be to buy yourself a lower priced ati 4xxx series that has the s-video to component dongle adapter (which should be included with the card, red+green+blue connector thingy). The s-video on the card is specialized since it has extra pins inside to carry a high-def component signal.

You might be able to find one cheaper at newegg open box, or on ebay. Just make sure that HDTV component dongle is included.

Tube TV's aren't easy to mate with a PC when you have the wrong hardware, adapter cables are often specialized and only work with specific equipment, as you found out, and transcoders are often more expensive than video cards.

Go to this video card sub-menu, and on the left side menu look for Svideo-HDTV-out, then browse for a cheaper card you can afford. If the prices are still too high then grab some of the model numbers and plug them into google shopping or ebay to see if you can find it cheaper.
 
I was in the same position as you were OP. I have the 785G chipset but needed some video-out with composite and component. Before I got the 4850 card I manage to buy a cheap ASUS 3450 card off of ebay for ~$20.

I wish I knew that the 3450 card could hybrid cross-fire with the 785G. I would have like to just try it out for kicks.
 
Yes, it would, i saw that card earlier, and thought about linking it for you, But the s-video would be one notch worse in quality -vs- component, even on an SDTV, fuzzy text etc etc.

That videocard card is hardwired for that component dongle i linked earlier, but they don't include it for whatever reason.

Here's the cheapest price i could find on the component dongle ($11.99): http://cgi.ebay.com/Abit-Component-Output-Video-Cable-Dongle-AMD-ATI-Cards-/200325290373

$33 + $12 = $45 shipped. Still not a bad price imho.

You might be able to find something better or cheaper that already includes the component dongle. You would likely have to output a 640x480 resolution btw, or something like that, not sure what refresh rate though.

As DTN107 pointed out, Ebay may be your best bet.

Many tube TVs will actually accept 800x600. I had a 32" Magnavox that would. Of course, even 800x600 is very, very low by today's standards.

You're right, i almost forgot, that's still a decent step above 640x480 in image quality.

I'd try 800x600 first, via component preferably, i think it can pull off a 60hz refresh rate, can't remember for sure though.
 
I was just thinking about it, since my IGP is the Ati 4200, shouldn't there be a compatible DVI -> component adapter that works?
 
It is not about the "adapter". The ATi 4200 just does not make any analog signals for component out.

Hence why your earlier adapter didn't work.
 
I installed my brother's old 8400 with s-video on it, will I need to wipe the current drivers to get it to work? I know going ati->ati doesn't make me do that...

It probably doesn't accept 800x600, just 752x486 and the card will downscale the 800x600 to NTSC resoulution. My old ATI card would do 800x600 and 1024x768 and downscale it to 752x486 out of the S-video port.
 
OK Easiest solution is a VGA breakout cable. Plus it will still leave better quality then S-Video

doesn't the video card need to support component from the VGA port for those cables to work?

Not unless things have changed. I used to do audio video work (it was at the beginning of LCD & Plasma days) & we used those things constantly to conenct computers to LCD's. As at that point DVI wasnt even very common.
