Hi All


Scart to HDMI is anybody using this type ?

[roudoudou]

I saw some people using it successfully, not mine (because he's keeping 50Hz and i have only 60Hz screen?)


I've also seen a modification to handle better the signal on a Atari forum, just a resistor to add. I will try when i'll have time!


Do not put it in the trash!


ps: Now i'm using a generic RGB VGA converter

@roudoudou
I have just checked Pin 16 on the Scart socket and it is Grounded, hmmmm
Therefore it will only display Mono (Black and White).
I think I have a Faulty Converter.

Nope, that just means that it will only display composite, but it could still be in colour. It may only convert to composite and not RGB?

OK Thanks for that.


I thought that Pin 16 has 2 voltage levels
0 Volts -  Mono
1-5 Volts Colour RGB

It does, and as your attached list shows - 0V = Composite, not mono. Composite can be coloured too.

Ok I will do some more research.


Thanks for the Pointers.

I use one of these. For the 8 bit machines, I only get black and white output.
If I hook an original Xbox to it, it's colour.

So definitely don't bin it, it's not a fault with the device.

It's working as intended, but the intention is to convert Composite only, not RGB. Definitely shady, there is no need for a SCART socket here unless to fool the buyer into thinking the device may do RGB.

Good quality scan converters / upscalers are expensive.

Then it's the 8-bit computer producing the black and white composite signal, not the converter.

Yep, it's definitely not the device at all.

Thanks to all, I spent most of yesterday trying to make some sense of the MONO signal.
Your comments are helpful

Thanks

Is it an Acorn Electron? That only has mono composite.

Until you mod it to give colour composite (1 wire, 2 minutes).

Nope. Happened on both an Amstrad 6128+ and a Spectrum +2b using that converter.
I'll post screenies over the weekend when I get a bit more time.

[Bryce]

Neither of those produce a coloured composite signal, so of course it will be black and white if the convertor doesn't use the RGB signals. You could do the composite hack to the Spectrum UHF output and it would then give you colour.

Tried it on my grey +2 and ballsed it. Thankfully the TV with the SCART to HDMI adapter doesn't get used often so it's not bothering me too much.

Yes, never saw what Acorn were trying to achieve with that other than perhaps trying to give a lower spec than the BBC Micro.

[fgbrain]

yes, I also confirm this produces only black & white picture only 
but I like the audio. it is much louder and clearer than the scart only input in my LG monitor...

Could you point me to the instructions for that?

Article written by a really nice guy, I can recommend his mods It explains how to add colour to the composite or (even better) add an S-video output.

Hehehe, I see what you the nice guy did there!
