Wow that looks great!

I have an RGB-YUV converter already but it only works on TV's/Monitors that can handle Bi-level sync and of my 4 component equipped displays, 2 of them dont work with it.

How the composite video signal can be converted into a higher quality component RGB output seems a bit of a mystery too.


It's possible to strip the sync signal from composite and use that as part of the YUV conversion - I have one such adapter that does this. however our doesn't work on my Amiga's.

I must be doing something wrong because I am not getting any voltages off of those pins! Yes, the computer is turned on.  :)


No you arent, Amiga video isnt SCART therefore you wont measure any "flag" voltages for SCART to indicate 16:9 vs 4:3 etc.

Amiga video is just RGBs and some ground pins.

@jdryyz
the cable must be modified to provide expected voltages for new TVs. (pin 16 is most important)


The scart converters ignore the scart signaling pins so there's no point. He's in the USA and doesn't have scart on his tv.

Ignore the "make an RGB to component cable" suggestion, it's just ignorant!

The converters when powered up put out an OSD (on screen display) of the resolution as notification.  This lasts a second.  If you don't see it, then it it is broken.  Un-plug the power and plug it back in for this.


The RGB-YUV Converters dont, only the HDMI converters do which use a very basic video processor in them with OSD functionality.
