Would this work? VGA to RGB Scart Solution

[Don]

I am aware of the thread that details how to create a VGA to RGB Scart cable, but am wondering if this relatively cheap and straight foward approach will work..?

Take this cable and plug the VGA into your PC:

Then plug the 3 connectors into this scart adapter and plug that into your TV:

Thoughts??

No idea rly... I do forsee a possible problem though:

VGA -> RGB does indeed supply you with the RGB signal and its grounds, but I don't see where the two sync wires are hiding... That means the signal would make its way over to the tv unsynced. The tv would then try to display it (you will be able to recognize it as windows), but you won't be able to do anything with it.

That's my thought of it ofcourse... Don't just take my word for it, wait for second/third opinions.

What you COULD do ofcourse is take that setup as a start and just add 3 wires on the exterior of the cable to get the syncsignal over (that would ofcourse involve you having to break open both ends). You'd have to mingle with the VGA end anyways as you need to get the molex plug in there either way.

It's unlikely.

What that cable is for is something like a projector that has the ability to receive component signals through a VGA port. 

If your computer is unable to send component video over the pins of its video port then this will likely to be useless.

However,  it is possible that you could receive RGsB (sync on green) video over that cable.  That's IF your computer can send the right signal over the right pins, which it probably can't.

Then you will have to deal with the SCART adapter.  It is designed for a component signal, and a TV that can recieve component video over a SCART connector.  Most old SCART tv's cannot do this. I live in North America so I can't speak on the new ones.  I would say they can, but it's really a useless point since they will have RGB over the SCART connector and that' s what you want.

Additionally, you would need to find a way to provide sync to the SCART display.  I believe you would be able to split the green sync video to this purpose. 

Component video is not the same as RGB video, I encourage you to read about the differences.

Looks like you'll end up messing around with it a whole lot too in the end... So not a great solution there. Getting some CAT5 and making your own (buy a loose SCART and a loose VGA piece online) cable would most likely be as fast and even cheaper.

Getting some CAT5 and making your own

But it may not look real pretty.  Cat 5 is ~100 ohm impedance, video coax is 75 ohms.  It'll work, but you might get some smearing.  Someone will chime in shortly to correct me.

Could be... I personally don't have any experience with using CAT5 for it (just used an old SCART cable), but I've read multiple guides saying it'll work.
