DVI to Component...

[RiPPeN]

Ok here's the situation... I have a TV.... When i plug the SVideo from PC Video card to the tv it looks like utter ******...

I have seen however a thing that will turn my DVI into Component allowing me to plug it into the Component of the tv.... does anyone know if there will be a quality improvement? (i have a Nvidia GeForce 6800Ultra, it has 2 DVI outputs and Svideo)

I mean i know it SHOULD be an improvement technically, but will it be?

also, is this any good...? [link below]

any help would be GREATLY appreciated

Thanks,
Dan

Welcome to the forums.

While I have never tried component vs. S-Video against each other (because I lack any component input devices), the component should look a lot better. I know the technical details don't really matter to you but they almost always translate to real-world experience. Component is still analog but there is a big reason it should look better: the color components are split up more.

From Answers.com:

Most component video systems are variations of the red, green and blue signals that make up a television image. The simplest type, RGB, consists of the three discrete red, green and blue signals sent down three wires. This type is commonly used in Europe through SCART connectors. Outside Europe, it is generally used for computer monitors, but rarely for TV-type applications.

Another type consists of R-Y, B-Y and Y, delivered the same way. This is the signal type that is usually meant when people talk of component video today. Y is the luminance channel, B-Y (also called U or Cb) is the blue component minus the luminance information, and R-Y (also called V or Cr) is the red component minus the luminance information. Variants of this format include YUV, YCbCr, YPbPr and YIQ.

Yeah, that adapter looks like what you need. Though I don't recall DVI-I (also transmits VGA) being convertible to component with such ease as a simple adapter? Maybe someone else can shine light on this. Good luck.

Those looks like OEM version of the ATI HDTV adaptor (old ones). Since your card is Nvidia I doubt it'll work.

Some video cards have good video out and some don't. What card do you have?

Brand is irrelvant here. ATI and NVIDIA do use proprietary (I think) VIVO connectors but this is just a DVI port.

Brand is important with the ATI DVI adaptor, in fact only specific cards are supported by that adaptor, and no Nvidia cards are supported at all.

I would make sure your card was supported by the adaptor.

Depends on your display, and your hardware. DVI and YPbPr carry high bandwidth signals hence higher resolution and seperate color components, while s-video is limited to 480i and seperated Luminance and Chromiance components.

The OP said he had a GeForce 6800 Ultra with 2 DVI outputs.

Welcome to AT.

This adapter will not work with your card.

When I was looking for component out options I was told by a couple manufacturers that there were no options for a standard 6800gt (and I think 6800 ultra).
At the time I looked a few months ago only the 6600gt cards and a couple 6800 vanilla cards had Component output and when they did it was through an adapter pugged into the "s-video" type connection, not the DVI port.

I used the adapter you linked to with a 9800pro. The adapter doesn't even work on all ATI cards.

What kind of TV do you have? If it's not an HDTV (or EDTV) then component is going to look just about the same as s-video anyway.

For real? I thought component output was integrated on the 6800 and just required the mini-DIN cable. But yeah, don't expect increased useability as far as text with an SDTV, but just a bit of an improvement for movies.

 

[Fox5]

Some nvidia cards can have a mini-DIN cable attachment that will do component out, besides that you could get an DVI to VGA convertor(one probably came with your card), and then buy an expensive VGA to component transcoder.

BTW, component is essentially VGA quality, probably what VGA would look like over a cheap VGA cable.(normally component cables don't have a high amount of shielding, most aren't used for more than 480p res anyhow, component also lacks VSYNC because TVs only refresh at one rate anyhow)

 

[kylebisme]

I thought component had vertical and hormonal sync signals compressed into the connection? I do know that I was able to change the refresh rate when using component out from my x800xt-pe.

Composite signals carry sync messages and closed captioning. Component is just a more split-up version so I'd assume it does too. In fact, any analog connection needs to carry sync signals AFAIK. Don't quote me on it though.

whoops, sorry (I quoted you)

 

[Boogak]

You could try a Audio Authority VGA to Component Transcoder, which is alot pricier but will work with any video card. You'd also have to know how to set your own custom resolution and timings to output the correct signal to your TV.

As for quality differences, it's definitely alot sharper and focused with component out versus s-video, text is actually readable.
