3 x BNC VGA = Component Video ??? - Page 2

Mikael Abdellah · 31st January 2006, 04:38 AM

so basically i have to either find or build a gadget that converts the component signal in to rgb withou converting resolution and sync and then add the sync on the green again and that might work?

Or you could try making up a RGB from the scart output to VGA.

My guess is that the RGB output in the scart is much worse than the component video. But I could be wrong. I guess it's worth a try at least.

RGB is the highest quality signal available (which is why computer monitors use it), so it should be a better quality picture than component video.

There also seems a little confusion over the monitor?, it keeps being described as 'VGA'?, but then you said it was a professional video monitor? - these are usually completely different devices (with completely different signals), although some multi-sync VGA monitors will switch low enough for video signals (but they are very rare).

What I meant was that I assumed that the signal present in the SCART ouptut would be of poorer qualty that the component output. I have never regarded the SCART connector as a high qyality signal connector but I might be wrong.

About the monitor. It is a Panasonic DT-2930MS. It is a multisync monitor with both VGA and analog video inputs. The picture I have got with regular composite video signals has been far from impressive. Maybe I should first try the RGB signal from the SCART connector.

Those specs indicate that it has a component (not composite) video input. If you have these signals available use them.
From the rest of the thread, it's not clear to me what your source provides - RGB, component (luma + chroma) or composite. Some graphics cards have S-video out, which is much the same as component.
You *may* have RGB available at the SCART socket - it's specified, but not always implemented. (But what's the SCART on - are we talking about a graphics card or something else?).

The source here is a Denon DVD-1920 DVD player with a analog devices ADV7322 video DAC. The player has component, composite and scart output. The scart connector is stated to have RGB output.

dnsey, Component is a 3wire system with each wire carrying a mixture of RGB ( the aim was to match the average signal levels or something).

You may know that but your description makes it sound like a 2wire system.

dnsey · 1st February 2006, 11:34 AM

OK, thanks,that's clearer.

Composite video is 'one wire'
Component video is 'two wire'
RGB is 'three wire' plus syncs, which vary with the system.

The specs in the link seem to indicate that your monitor has component video in, which should work fine with your player.

I'm still puzzled though - where does VGA come ito this
