Any chance of component out on a nvida cards VGA?

Or DVI? I have a few quaddro NVS 280 cards that I am hoping to drive a few large screens over a moderate distance using component since the cabling is already in the walls.

I know some ATI cards can have a reg-hack to reprogram the DAC to output component with the sync in the right place and everything. Not to sure on nvidia tho.

Otherwise I will have to get some VGA to component transcoders, which I would rather not at this stage.

the the nVidia card in my mame cab has component out, I cant remember the card specifics right now but I'll check when I get home. I knows its a BFG GeForce something or other I'll post after work, but I think your question is if you can hack the DAC to output component through the VGA port?

Some nvidia cards have a dedicated "HDTV output" port that uses a breakout cable for component.  The DACs on the nvidia stuff are onboard the main GPU, and I don't think there's an output colorspace option.  There was a hack floating around for X at one point that basically changed the framebuffer presented to the hardware to YCbCr which, combined with a SoG setting (supported by most cards) enabled YPbPr component output from almost anything, but I never saw such a hack for Windows.

If your monitors/TVs have RGB/VGA inputs and you have 3 coax cables on which you were planning to run YPbPr component, just run RGB instead with SoG.  Use a breakout cable on both ends to adapt to your three coax cables.  If you've got CAT5, there are also passive (and active/amplified) adapters to let you run video over that with very good results.

Yeah, unfortunatly there have to be several flash animations running at once on a single PC and I have several PCI quaddro NVS 280 cards which are pretty crap for 3d but will do the trick.

It may be all ok tho, as they think the place that it will be happening will have been refitted with HDMI distribution by the time its needed, as the component amps and splitters were only meant to do SD, they look lousy on 1080p, so I may just need to get a few HDMI-DVI cables... Otherwise may have secured a place that will rent the transcoders,

To do it otherwise would mean finding some PCIe1 cards, which seem to be as rare as anything and I have not tested them so no idea if they will keep up, the quadro's will even at 1920x1440 which is the highest res I can get a screen here to do. Not tried it with 2 of them in the machine, but a PCIe card, the quadro will do 4 outputs fine.
