Title: Dvi Cable? Component to DVI?
Post by: joe912 on January 20, 2004, 06:20:00 PM

could i make a vga cable and then use the converter that came with my vid card to hook it up to my hdtv???

No you couldnt, unless your TV takes analog signals. The DVI converter doesn't change the signal, but rather the analog pin positions. In a DVI connector, the analog pins used for this purpose are those surrounding the "-" sign pin (the wide pin).

This was already covered in this thread

To be more specific, your computer's DVI port outputs both VGA and DVI. That cable it came with just grabs the VGA and signal and makes it into a standard VGA plug to connect to old non-DVI monitors. You're talking $300 to get an adapter to convert a VGA signal to DVI.

You are the only person I know of that's seen even a rumor of it actually happening. I would assume that if it is actually under development there is no publically released ETA. Personally, most TVs have only one and more often none DVI ports (some newer ones have a couple but let's face it, these are generally reserved for HDTV, DVD, and possibly HTPC sources rather than an Xbox) I can't imagine there's anything more than a sliver of demand for this item - most of us never thought there was any chance of seeing one produced. Have to wait and see but I wouldn't hold your breath.

I think I am right in saying that the DVI 1.0 standard includes analogue video in its protocol. Analogue video is no step up of course. I believe that I am also right in saying that DVI digital video requires handshaking. Something the XBOX can't do, me thinks.

My HDTV component cables on my TV are taken up by my HDTV Set top reciever and me progressive scan DVD player. how do I get my hdtv in there too

In the meantime, my set only has one DVI connection which is reserved for the HD DTivo. I guess when a receiver with DVI switching capability comes out below $500, then thats when I can take advantage of this...

Hiya,
would gladly put my hand up for a set of DVI cables from Xbox thro my projector/home theatre, actually thought they would've held off with DVI until the fabled Xbox2, but would gladly have them runnin thro the current xbox.
With the newer games pushing the HDTV envelope, it would make a great improvement. Plz keep us updated on this one.
Cheers,
ngarutoa

External switcher - I think Pelican makes one that a lot of people have been happy with (including those on AVSforum who are typically more discriminating than your average xbox-scene.com poster).

If you have a decent HT product with good bandwidth video switching you can send YPb and YPr through 'S' Video inputs and Y through composite. So if you had a receiver with 8 video inputs you can use three of them for HDTV and the rest as normal. Make sure Y is on composite as most displays have the composite and luminance sharing connections. If you are running @ 15KHz any video switcher will do, if you are running at 31KHz something a lot better would more preferable, such as 10MHz.

Post by: poiygon on November 05, 2004, 04:26:00 PM

From what I've been told, XBox does not have a digital video output. Therefore, the only way to get DVI would be to use a VGA->DVI cable from a VGA adapter. By then you're video would probably look worse than component.

(reason being, component still converts the digital HD signal to analog then back to digital; with DVI, it's an unfiltered process).

if that is true then for me that great. dvi/hdmi cable should improve PQ alot .

oc.uk have the screen for sale as well http://www.overclockers.co.uk/acatalog/lcd_tv.html

As spillage said you'd need support for DVI at the graphics chip level, which as far as I know was not built into the XBOX so this will never happen.

As for analog DVI that wouldn't work either as most (all?) HDTVs only support DVI-D (digital only) input and not DVI-A or DVI-I. Lastly analog over DVI is just VGA, which you can get with some 3rd party cables.

I expect the XBOX 2 and PS3 to support DVI out of the box.

BTW here's the only way I know of getting an XBOX to do DVI. It's a $300 adapter box though:

If the display you have supports the resolutions you want in the analogue domain, this diagram will enable you to make an VGA to DVI lead. It does NOT convert anything it is simply an interface.

im looking for a component to dvi adapter, searching google comes up with tons of links for dvi to component, most say dvi in component out, will these work both ways and convert dvi/component and also component/dvi cause everything ive read points to dvi/component only, reason being is i have a set that only has dvi and im looking to convert xbox hd pack to dvi so i can use this display

The least expensive adapter I know of that converts component to DVI is the DVDO iScan HD and it MSRPs at $1,200 USD.

You can find a VGA to DVI adapter for around $300.

No, those only extract the analog VGA (DVI-A) signal included in DVI-I. To go the other way, analog to digital, you need a cpu processor to digitize the analog signal in real time to DVI-D.

i have a vga to dvi cable, in which case i can use a vga switcher that outputs to a vga cable(not HD or anything just to use my pc monitor to play xbox on) but has composite and svid input so i can use the the M$ svid cable to the switcher and the switchers vga out with my vga/dvi cable but damn that to many adapters, im looking to connect the M$ HD pack straight to a dvi connector to go to my set so i get the least interferience

basically i have a projector tha has composite,svid and dvi

but my have the M$ HD pack and need to get an component to DVI adapter

i hope that shit aint as expensive as MR ED says, i feel if i use this VGA switcher with svid to vga to dvi everything will look like shit, i havent tried it yet as my vga switcher is burried in a box somewhere but i just asuumed it would look like ass

vga to dvi cable

What you have is a VGA to DVI-I cable. Your monitor probably has a DVI-I plug which should work, but some monitors have a DVI-D plug, in which case that wouldn't work.

would this work?

Xbox -> Component male(hd pack) -> "female-female component (thingy)*" -> (male)Component-VGA(adapter) ->VGA-DVI(adapter)?

To my tv (philips 32PF5320/10) I got a DVI-VGA adapter .
This part was missing so I dont know ecatly how it loks, but I asume the Dvi side is male and the vga part is female. I will have to go back to the store) and VGA to YPbPr-Cinch cable**.

Sins I got a simple DVI-VGA adapter I asume the TV can handle analog signal.

I know it probobly would be easier to build a VGA cable, but now I found a component cable at link-sang for $12 ink shipping so I would like to try this first.

* can anyone find one of these?
** why is these male? I´m I supposed to use the DVI as an out-port?

edit: I have a DVD-I(HD/PC) port on the LCD

If you really have a DVI-I and not a DVI-D connector on your monitor and the component to VGA adapter works (I've never seen one) I guess this might work.

I don't think that'll work.. DVI to VGA adapters are to convert signals down to VGA so you can use a standard monitor with a DVI video card. I doubt it works the other way around. And as far as I know, the graphics on the xbox don't have provisions for a true DVI signal.

Title: Dvi Cable? Component to DVI?
Post by: Mr Ed on November 23, 2003, 06:17:00 AM

Uh yeah. Remember VGA is analog. DVI is digital you can't just convert one to the other.

How does a DVI to VGA adapter work? Well the DVI spec allows VGA to be sent on a few pins as well. The adapter just takes the VGA analog signal and adapts it to a standard size VGA plug, so you can look at a DVI plug and know there are actually two signals on it, DVI and VGA. The converter just splits out the VGA signal.

does any one knows if theres a DVI cable for the Xbox or how to make one .
i have a Samsung WS 47inch and the only connection on the TV thats supports the 720P is the DVI input .the rest ony support the 480p,480i or1080i
please help

Post by: ChrisF on December 09, 2003, 08:46:00 PM

There is no DVI cable. All of the current xbox outputs are analog. DVI is designed for a digital signal. I'm sure anything is possible but it would be a monumental effort and likely require a complete re-engineering of the xbox.

They do make a 15pin vga to DVI cable. You could then use this cable in conjunction with the x2vga transcoder, or with the ms hd pack plus vga bios. I would definently try this route if your tv supports 720p in dvi. ;)

Yeah, that "cable" that converts VGA to DVI is $300. It includes a box that does the actual conversion. Remember that VGA is crappy old analog, so the box needs to have an A/D converter to actually digitize the analog VGA signal to DVI. And since you signal is only as good as the weakest link, it won't look any better than a straight VGA signal, so there is no benefit in spending $300 to convert VGA to DVI.

If you still want to buy one, you can get one here:

You don't need that expensive box to do this. They make simple a simple $15 cable that will do this. Check here. And yes, the best you'll get is vga analog, but this is pretty damn good; just as good as what a regular vga 15pin vga monitor gets in conjuction with a computer. The benefit is this is the only way for him to get native 720p, and for $15 it is a very good idea.

Post by: Mr Ed on December 12, 2003, 05:09:00 PM

Ok, that cable doesn't really convert VGA to DVI. But it does pass through the VGA signals on the DVI-A pins of a DVI-I connector.

So I guess I have to ask this question...is DVI on an HDTV DVI-D (I thought it was) which can't handle an analog VGA signal, or is it DVI-I which can? If HDTVs are only DVI-D, then this cable won't work.
