DVI to Component question

[DirtyDachshunds]

I have a 27" CRT TV that I want to use as my arcade monitor.  My computer display output is DVI and the component is Y, Pb, Pr.  I got a DVI to Y, Pb, Pr adapter and still can't get the TV to work with the computer.
When I connect the TV there is disturbance on the TV and occasionally I can briefly see my desktop, although very distorted.  I can't seem to figure out how to interface with the TV.
My computer is running Win 7x64, with a Geforce 8800 GT vid card.

Any help is appreciated.  I'll try anything

Thanks guys,
Cheers

Only when I scan to the component input do I see my computer input (although distorted), after a few seconds it then returns to a solid blue screen.

Most DVI to component adapters are meant for ATI cards that support them.  

The component output apparently takes a different cable.

8800 component

The specs from my Nvidia card say:
Integrated HDTV encoder provides analog TV-output (Component/Composite/S-Video) up to 1080i resolution

I can see the signal getting to the TV, just brielfy and distorted, which is why I think it could be a setting issue?
My TV also has an S-Video input, so if all hope is lost I can try to connect DVI to S-video.

The card can provide component by the spec but it does not say it is via the DVI.   What I was trying to point out was that it is from the other connector and takes a special cable to provide component.  May not be the same card as yours but the info came up when I searched on how to get component from an 8800 card.

The flyer seems to show an S-video to component adapter.  Maybe that is the route I should have gone instead of my DVI to component, although the flyer also says:

You may also use the DVI
connection (see figure 1) on the video
card rear bracket provided your television supports
it and you have obtained the proper
DVI cable for your television.

Do you think the signal quality will be any worse coming from S-video instead of DVI?

Thanks for all the help

I don't think it is a straight s vid just like the ati cards are not just dvi.   Not sure the difference but it looks like the recommended cable at least for the card shown.

This is the cable that came with 2 of my Nvidia cards.

I'll start digging in my closet tonight.  I should have that cable somewhere.

Thanks again

To elaborate on BobA's post, it LOOKs like Svideo but has more pins.

Notice the diagrams there.

So I found that cable boba suggested, connected up to the TV and when booting everything looked great!  But once it got to my desktop the TV kept scanning the screen vertically like the tracking needed adjusting.

But at least I am getting a signal!

Yes Nvdia delivers its component on the 7 Pin S-Video like cable adapter.  A few tweaks and you will be good to go.

It's been a long time since I looked into video cards that would handle DVI to component, but I'd be interested in know what recent cards could do it.

Almost all of them can.  My problem was that I was trying to go DVI to component on a Geforce 8800.  And I didn't realize the Geforce cards have an additional port (looks like an s-video) specifically meant for component output.    The graphics card even comes with the cable....which I totally forgot about.

However ATI cards to use DVI ports for component outputs.

Hope this helps.

Historically I was always under the impression that ATI cards were considered to have among the better quality TV-out (I assume this extends to component). Can anyone comment or expand on that notion?

DirtyDachshunds I'm curious how your setup is turning out. I'm using a similar setup. 27" CRT TV with component in and an 8800gts with provided adapter. My setup is working but it needs some tweaks.   

[Blanka]

Did you try the correct resolution/refresh rate. If it is outputting fullHD over component, your 27 inch TV will probably throw up over that signal.

[Epyx]

The S-video/component being better on ATI than Nvidia or vice versa switches from model to driver etc...I don't believe it is a steady rule either way and I have used a ton of both cards over the years.

Just remember that on a TV the only S-Video and Component will only work over the analogue (NTSC tv that is) TV Out port on the video card...the DVI digital to Component cable connections won't work unless the DVI connector (some ATI cards) supports the analogue signal.

IE I have an Nvidia 8800GTX that will work component via the round 7 pin tv out port but not via a DVI to component adapter on the DVI port. Some 480P tvs may work.

[DirtyDachshunds]

The only problem that I am having now is that the edges of my TV aren't quite right.  ie a straight border (from a window or what have you) on the left and right sides of my TV are curved in.  It seems worse in the lower part of the TV.  I don't have this problem using the other TV inputs.

Does yours look like mine?
The strait lines....mine is pinched in the middle.
It is less noticeable when playing a game.

Yes exactly!  Have you found out a way to solve this?

I haven't had time to play with it since I took that pic. I plan to try some other video cards I have and see if it makes any difference. I have a GTX 260 and a 7600GS that have the same s-video like connector I may try out this weekend. Bit of a pain to do during the week as my HTPC doubles as my mame cab computer right now.
