I have recently found a pair of Hantarex CT29 IDTV2 monitors that were going to be thrown away. These monitors can display signals from 15Khz up to SVGA and are quite something but I can't really find any documentation on them.
Here is a quick look at the back of the monitors :


The DB15 VGA input works great and playing Cave ports on my Xbox 360 on such a display is a dream come true !

The problem is that I would like to connect my 15Khz consoles (PS1/P2/MD/Snes) using the DB9 RGB input. I would like to use a female Scart to DB9 cable so that I can still use my scart RGB cables.
I first followed an advice given to another French dude who recently found a 34" unit and bought the following cable :

I did not work and nothing appeared on screen. I then tested a PS1 S-video cable and I have a fine picture which meant that the monitors worked OK with low res.
Any idea ?
Thanks a lot
