DVI to Component Cable

[Juice Box]

I currently have an Nvidia 6800GT and wanted to hook it up to my receiver which has component in. Would something like This work for what I need? I also would like to know how I can get the computer to output in 720P, as that is the native res. of the projector I am going to be feeding the signal into.


Only reason I ask is that on the bottom of the auction it says: (*)The Cable Not Support your Computer Monitor Video Port, or Y , Cr, Cb Video. Your Video Source Must Provide a YpbPr Component Video Signal form the DVI-I Video Ports to Use Cable

Wasn't sure if my video card had that kind of output. Thanks in advance for the help!

I think that cable only works with a couple differant videocards.

Does your PJ have any VGA or DVI inputs?

Well, it has a VGA input,. but that is how you plug in the component cables from the receiver, so it'd be a matter of switching that and the component cable adapter anytime I wanted to use the PC. Is there no way I can get my video card to output through component cables?

 

[SonicIce]

Depending on your videocard you might be able to use component with an adaptor thingy but some only have s-video. There is no such thing as a VGA to component cable since VGA transmits red, green, and blue data while component transmits lumanance and chromanance data. You can buy a transcoder for like 60 bucks but i'm not sure how good the quality would be. That is unless your PJ accepts RGB thru component. Which PJ do you have?

anybody care to chime in and correct me if im wrong on anything?

Optoma MovieTime DV10. The component-to-VGA adapter is how I hook component sources up to it. Which leads me to believe It'd work...I just would rather use component than VGA so I dont have to switch between cables everytime I wanna use the media center PC

 

[SonicIce]

oh so you just want to leave the receiver connected to the pj all the time and use the receiver to switch inputs?

That was the plan...is it even possible?

 

[SonicIce]

The VGA port on your projector is actually VGA port and a component port in disguise combined. Thats why the component-out of receiver is able to go thru componenet -> VGA cable to PJ. Unfortunately I don't think you will be able to use that ebay cable to connect your 6800 GT to receiver because the 68gt is only made to output regular VGA (thru dvi->vga adaptor if nessacery). Which videocard exactly do you have?

if he uses component won;t that be limited to 480p? I know that straight component is limited to 480p by really odd and annoing communications laws but I'm not sure how that would work if you go from the DVI port to a component cable. I guess theoretically they should be able to push high def, maybe not 1080p but surely 720p/1080i. I know I never thought there was a big difference between component and VGA until I used both with my 360. The differences are astounding. Phantasy Star Online through componet looks like it did on dreamcast, through VGA it looks like a next gen game. Almost all the games I've played look significantly better through VGA than they do through component. Just my .02

*double take*

You're completely wrong on many counts. Component is THE standard for analog HD transmission -- even up to 1080p*. You didn't hook up your component connection correct -- that, or there is a problem with your display device accepting component.


*It's possible, but rare to find devices that support 1080p through component. 99.999% will support 720p or 1080i.

 

[morgash]

ahh my fault. I transcribed that incorrectly. It is in fact most televisions that will not support more than 480p over component. I know for a fact that Toshiba, Samsung, and Sony all have "upscaling" DVD players that only upscale past 480p if you use HDMI (I have had all three, quite expensive so I took them back.) Also the 360's image quality differences appear to simply be the absolute complete and total dominance VGA has over component, it is simply a much much better way to transmit a video signal. HERE is a link briefly going over the copyright laws I was speaking of. The problem is component is unprotected media wise. The VGA cable however is completely exempt from these copyrights, which allows you to do whatever the hell you want with it

And on a side note, no i didn't connect my component up wrong, I know perfectly well how to hook HD connections up. The fault lies with MS, not me.

And one more thing, upconverting is the main thing that is not allowed over component because of copy protections.

Upconverting DVD players tout their abilities to make your DVDs look even better on your HDTV. But if you bought your HDTV a few years ago and have only component-video inputs, you're probably out of luck. Because of Hollywood's aversion to delivering high-def via analog, DVD players that are allowed to bear the HDMI logo can upscale only over copyright-protected ports, such as HDMI or HDCP-enabled DVI ports. How does NeoDigits' Helios HVD2085 fit into this mess? Well, the HVD2085 has somehow gotten around the restriction (hint: it doesn't have the logo) and offers upconversion over both its HDMI and component-video outputs.

lol thread takeover, and I'm sorry but I have to do it.

AND the killing blow:

POW!!!

The defense rests.

[Juice Box]

Haha....I come back to this? So, is the general concensus that it will or won't work? lol

And if not...how can I get it to?

There were a few players that could upconvert to 720p / 1080i with component but those aren't around anymore for copy protection issues afaik.

Most televisions will support above 480p from component, it is SD DVD players that normally do not. The TVs have no problems connecting via component. That's how most people are using their HD cable boxes.

No problem using component to do 720p to a projector from a computer.

This is about new players and sources not having HD over component. I don't see what this has to do with the thread.

That cable will not work. That one is similar to the kind of cables that would allow you to convert the DVI-I output of cards like the 9800pro to Component.

If BFG does not have a cable that works with your card, you're probably SOL for an easy way to do it and maintain quality.

Yeah, the 6800 series do not have the "HDTV" output that would be used on the 6XXX series. On a card like the 6600gt, you can see that you get a "HDTV / S-Video Out". That's the kind of connection I'm using with my own eVGA 6600gt. One of the reasons I didn't get a 6800gt was the lack of component output (my Infocus 4805 I had as the time didn't have a simple solution to connect VGA or DVI without a special adapter).

The 6XXX series of cards used an output that looked like s-video that could be used to transmit either s-video or component. The BFG 6800gt OC cards only allow regular s-video out of their cards, so there is no easy way to get component out of them.

 

[SonicIce]

i think that cleared everything up. you're gunna have to switch cables to use your pc .

i think only other solution is to buy a transcoder but i dunno how good they are. prolly not worth it.

 

[Juice Box]

Well, would using the svideo out port allow me to run 720p for games and stuff. The receiver and projector both have svideo out/inputs...so I could just end up running a 3rd cable from the receiver to the projector (composite, component, and svideo)...if that'd work. I don't know enough about outputting Hidef resolutions.

That being said, will i be able to output 720p via VGA, if I do the "cable swap" method?

S-Video won't be sufficient. The 68gt can output 1024x768 over s-vid but it's blurry and not any better looking than 480i. The pj might not accept higher than 480i over s-vid anyway which nothing does really. You could try it if you have a cable lying around but the quality wont be very good. The cable swap method, however, will look exceptionally good, even better than component.

Will I be able to specify to output 720p via VGA? I don't mind having to swap cables if I am going to get a good-looking image from the computer. (I mainly am going to use it as a media center as well as gaming PC on the projector.....do a lot of games have wide-screen resolutions? or will this be pointless?)

 

[YOyoYOhowsDAjello]

Yeah, s-video will look like crap.

The only thing that I can think of as a problem running 720p to the VGA input is if the projector only supports certain resolutions over VGA and certain resolutions when it's in "component" mode.

Yeah, a lot of games support widescreen, and there are widescreen gaming sites and forums to help you enable widescreen resolutions for some games. Google it.

I guess I'll have to play around with it and see....I think it'll run any resolution I feed into it as it simply scales down everything to its native 480p (I think that's it...could be wrong) Before you say "oh that's crap"...every HDTV 1080i/720p input I've displayed on it looks crisp and awesome, so I could care less that it is scaling it down, as it does a damn good job

Boy am i glad I bought that 100ft VGA cable last summer....

 

[SonicIce]

wow 100ft. just hope it doesn't pick up any interference. btw i love your juice box pic.
