Need to use Component out to TV using G400 max! What cable?

[Rags]

If I were you, I would listen to Maggi, he's already given you your answer

[ccoltas]

Ashley said I would need a converter, not just a cable. Matrox hardware in itself does not support YPbPr direct drive.

Matrox tech mentioned they don't support sync on Green.

From your link, I still don't know how to make a cable that goes from SVGA, or S-video to YPbPr. I know the Y is the same in component and S-video, its the C:0.286 Vp-p (burst signal), 75 ohms thats not the same as the PbPr of 0.7 Vp-p, 75 ohms.

I doubt your TV is a sync on green component connector. Maggi has the answer you are looking for if you want to use the connectors.

I think some may be confusing composite video with component video. If you want to use *component* video (YPbPr), follow xortam's advice above.

RGsB (your "Sync-on-Green using 3 cables") and YPbPr only SEEM to be similar because they both have three channels, and the composite sync in carried on the Y/G channel. But they are not compatible and it is not just a "BNC-to-RCA" issue.

You need a converter if you want to convert RGB to component video.

[Maggi]

uhm right ... your TV does not support RGB.

I was thinking that you probably mixed it up and thought component signal (aka Y-UV) would be also be used for describing an RGB port.

What you would need is a piece of electronics that splits the chrominance signal (provided by the G4x0) into U and V (or Pb & Pr respectively), but I don't think that it can increase the picture quality, since the signal is already put into one signal line).

In your case, Id go for the far easier route and hook it up using s-video (aka Y-C) connections. I do it for myself and my cable is something like 15 meters long.

Cheers,

Fair enough. I am using the S-video and its not too bad. Its just that there are visible horizontal lines on the TV screen. Its not too bad except when you are up close though.

So you're saying the chrominance signal would have to be split? Is that in terms of the S-video? or in terms of the SVGA?

So since there was a little confusion here, which of Xortam's advice am I to follow? I would still need something to convert the signal to Y Pr Pb from which, SVGA or S-video? I just don't know what would be easier to find.

thanks again folks, the TV looks ok so far, I'm just spoiled by seeing DVD on a sharp 19" monitor.

Its not really that complicated. Your JVC accepts component video, s-video, and composite video, but not RGB.

For the highest possible quality, you want to use component video and for that you need a converter like the Audio Authority xortam suggested.

If you do not want to fork out the money for a RGB-to-YPbPr converter, use s-video as maggi suggested.

(There is absolutely no point whatsoever in trying to convert s-video to component video.)

[Maggi]

Unless you have a 100Hz TV, you just discovered the lack of quality that comes with any TV standard except for HDTV (no matter which flavor it shall finally be) ...

PAL is 720x576 pixels, split into two fields (720x288), both shown one after each other (interlacing) in 50Hz.

Not really comparable to 1280x960@100Hz, right ?

...

S-video = Y/C
Y=luminance (amount of lightness)
C=chrominance (colorvalue)

splitting the chroma signal into U & V (or Pb & Pr) components would give you the desired component signal that your TV requires, but if you're heading for a good quality converter, you'd have to pay a fortune ...

Maybe even too much for you ...

I hope this gives you an idea of what you're talking about and maybe you can even find an affordable alternative.

forgot the rear panel ...

[Maggi]

btw, Ashley ... your latest build of PS now properly reflects my G450 clocks ...

[ccoltas]

Thanks for the info. Like I said, I'd like better, but it looks like in order to get better video at 32" you need HDTV for higher resolutions, higher refresh rate, progressive rather than interlaced display and the associated higher bandwidth that all the above requires? And thats expensive!

What is better? 480p or 1080i?

I looked at the link about the 3:2 pull down and interlacing and I was wondering, how does my Pioneer DVD drive, the Matrox DVD player software and video card deal with the DVD signal? The signal to the monitor must be progressive, and the signal going to the TV must be interlaced, so when is it adjusted for each output? For instance, does the Matrox card and software decode the DVD movie in a progressive manner so it goes straight to the monitor? and in order to go to TV out NTSC, the matrox card converts it to interlaced? or is the Matrox DVD software player and card just like todays stand alone interlaced DVD players??

it's worth a read

Maggi, after Chris said he only wanted a quick answer and didn't want to do the neccessary research first, sure looks like he pulled an assbackward to me.

[ccoltas]

Everyone who has helped me get info, thanks.

You're welcome Chris
